# Leiningen plugin to verify a provider [version 2.2.14+, 3.0.3+]
Leiningen plugin for verifying pacts against a provider. The plugin provides a `pact-verify` task which will verify all
configured pacts against your provider.
## To Use It
### 1. Add the plugin to your project plugins, preferably in it's own profile.
```clojure
:profiles {
:pact {
:plugins [[au.com.dius/pact-jvm-provider-lein_2.11 "3.2.11" :exclusions [commons-logging]]]
:dependencies [[ch.qos.logback/logback-core "1.1.3"]
[ch.qos.logback/logback-classic "1.1.3"]
[org.apache.httpcomponents/httpclient "4.4.1"]]
}}}
```
### 2. Define the pacts between your consumers and providers
You define all the providers and consumers within the `:pact` configuration element of your project.
```clojure
:pact {
:service-providers {
; You can define as many as you need, but each must have a unique name
:provider1 {
; All the provider properties are optional, and have sensible defaults (shown below)
:protocol "http"
:host "localhost"
:port 8080
:path "/"
:has-pact-with {
; Again, you can define as many consumers for each provider as you need, but each must have a unique name
:consumer1 {
; pact file can be either a path or an URL
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
### 3. Execute `lein with-profile pact pact-verify`
You will have to have your provider running for this to pass.
## Enabling insecure SSL
For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting
`:insecure true` on the provider.
```clojure
:pact {
:service-providers {
:provider1 {
:protocol "https"
:host "localhost"
:port 8443
:insecure true
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
## Specifying a custom trust store
For environments that are running their own certificate chains:
```clojure
:pact {
:service-providers {
:provider1 {
:protocol "https"
:host "localhost"
:port 8443
:trust-store "relative/path/to/trustStore.jks"
:trust-store-password "changeme"
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
`:trust-store` is relative to the current working (build) directory. `:trust-store-password` defaults to `changeit`.
NOTE: The hostname will still be verified against the certificate.
## Modifying the requests before they are sent
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The Leiningen plugin provides a request filter that can be
set to an anonymous function on the provider that will be called before the request is made. This function will receive the HttpRequest
object as a parameter.
```clojure
:pact {
:service-providers {
:provider1 {
; function that adds an Authorization header to each request
:request-filter #(.addHeader % "Authorization" "oauth-token eyJhbGciOiJSUzI1NiIsIm...")
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
## Modifying the HTTP Client Used
The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`).
This can be changed by specifying a function assigned to `:create-client` on the provider that returns a `CloseableHttpClient`.
The function will receive the provider info as a parameter.
## Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
## Plugin Properties
The following plugin options can be specified on the command line:
|Property|Description|
|--------|-----------|
|:pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors|
|:pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies [version 3.3.6+]|
|:pact.filter.consumers|Comma seperated list of consumer names to verify|
|:pact.filter.description|Only verify interactions whose description match the provided regular expression|
|:pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state|
|:pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to 'true' [version 3.5.18+]|
|:pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to 'true'|
Example, to run verification only for a particular consumer:
```
$ lein with-profile pact pact-verify :pact.filter.consumers=consumer2
```
## Provider States
For each provider you can specify a state change URL to use to switch the state of the provider. This URL will
receive the `providerState` description from the pact file before each interaction via a POST. The `:state-change-uses-body`
controls if the state is passed in the request body or as a query parameter.
These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given.
```clojure
:pact {
:service-providers {
:provider1 {
:state-change-url "http://localhost:8080/tasks/pactStateChange"
:state-change-uses-body false ; defaults to true
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
If the `:state-change-uses-body` is not specified, or is set to true, then the provider state description will be sent as
JSON in the body of the request. If it is set to false, it will passed as a query parameter.
As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before
it is sent. Set `:state-change-request-filter` to an anonymous function on the provider that will be called before the request is made.
## Filtering the interactions that are verified
You can filter the interactions that are run using three properties: `:pact.filter.consumers`, `:pact.filter.description` and `:pact.filter.providerState`.
Adding `:pact.filter.consumers=consumer1,consumer2` to the command line will only run the pact files for those
consumers (consumer1 and consumer2). Adding `:pact.filter.description=a request for payment.*` will only run those interactions
whose descriptions start with 'a request for payment'. `:pact.filter.providerState=.*payment` will match any interaction that
has a provider state that ends with payment, and `:pact.filter.providerState=` will match any interaction that does not have a
provider state.
## Starting and shutting down your provider
For the pact verification to run, the provider needs to be running. Leiningen provides a `do` task that can chain tasks
together. So, by creating a `start-app` and `terminate-app` alias, you could so something like:
$ lein with-profile pact do start-app, pact-verify, terminate-app
However, if the pact verification fails the build will abort without running the `terminate-app` task. To have the
start and terminate tasks always run regardless of the state of the verification, you can assign them to `:start-provider-task`
and `:terminate-provider-task` on the provider.
```clojure
:aliases {"start-app" ^{:doc "Starts the app"}
["tasks to start app ..."] ; insert tasks to start the app here
"terminate-app" ^{:doc "Kills the app"}
["tasks to terminate app ..."] ; insert tasks to stop the app here
}
:pact {
:service-providers {
:provider1 {
:start-provider-task "start-app"
:terminate-provider-task "terminate-app"
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```
Then you can just run:
$ lein with-profile pact pact-verify
and the `start-app` and `terminate-app` tasks will run before and after the provider verification.
## Specifying the provider hostname at runtime [3.0.4+]
If you need to calculate the provider hostname at runtime (for instance it is run as a new docker container or
AWS instance), you can give an anonymous function as the provider host that returns the host name. The function
will receive the provider information as a parameter.
```clojure
:pact {
:service-providers {
:provider1 {
:host #(calculate-host-name %)
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}
```

pact-jvm-provider-maven_2.11 from group au.com.dius (version 3.5.24)
Maven plugin to verify a provider
=================================
Maven plugin for verifying pacts against a provider.
The Maven plugin provides a `verify` goal which will verify all configured pacts against your provider.
## To Use It
### 1. Add the pact-jvm-provider-maven plugin to your `build` section of your pom file.
```xml
<build>
[...]
<plugins>
[...]
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
</plugin>
[...]
</plugins>
[...]
</build>
```
### 2. Define the pacts between your consumers and providers
You define all the providers and consumers within the configuration element of the maven plugin.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<consumers>
<!-- Again, you can define as many consumers for each provider as you need, but each must have a unique name -->
<consumer>
<name>consumer1</name>
<!-- currently supports a file path using pactFile or a URL using pactUrl -->
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### 3. Execute `mvn pact:verify`
You will have to have your provider running for this to pass.
## Verifying all pact files in a directory for a provider
You can specify a directory that contains pact files, and the Pact plugin will scan for all pact files that match that
provider and define a consumer for each pact file in the directory. Consumer name is read from contents of pact file.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying all pact files from multiple directories for a provider [3.5.18+]
If you want to specify multiple directories, you can use `pactFileDirectories`. The plugin will only fail the build if
no pact files are loaded after processing all the directories in the list.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.18</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectories>
<pactFileDirectory>path/to/pacts1</pactFileDirectory>
<pactFileDirectory>path/to/pacts2</pactFileDirectory>
</pactFileDirectories>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Enabling insecure SSL
For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting
`<insecure>true</insecure>` on the provider.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<insecure>true</insecure>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Specifying a custom trust store
For environments that are running their own certificate chains:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<trustStore>relative/path/to/trustStore.jks</trustStore>
<trustStorePassword>changeit</trustStorePassword>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
`trustStore` is either relative to the current working (build) directory. `trustStorePassword` defaults to `changeit`.
NOTE: The hostname will still be verified against the certificate.
## Modifying the requests before they are sent
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The Pact Maven plugin provides a request filter that can be
set to a Groovy script on the provider that will be called before the request is made. This script will receive the HttpRequest
bound to a variable named `request` prior to it being executed.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<requestFilter>
// This is a Groovy script that adds an Authorization header to each request
request.addHeader('Authorization', 'oauth-token eyJhbGciOiJSUzI1NiIsIm...')
</requestFilter>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
## Modifying the HTTP Client Used
The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`).
This can be changed by specifying a closure assigned to createClient on the provider that returns a CloseableHttpClient.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<createClient>
// This is a Groovy script that will enable the client to accept self-signed certificates
import org.apache.http.ssl.SSLContextBuilder
import org.apache.http.conn.ssl.NoopHostnameVerifier
import org.apache.http.impl.client.HttpClients
HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier())
.setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, { x509Certificates, s -> true })
.build())
.build()
</createClient>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Turning off URL decoding of the paths in the pact file
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
## Plugin Properties
The following plugin properties can be specified with `-Dproperty=value` on the command line or in the configuration section:
|Property|Description|
|--------|-----------|
|pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors|
|pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies|
|pact.filter.consumers|Comma separated list of consumer names to verify|
|pact.filter.description|Only verify interactions whose description match the provided regular expression|
|pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state|
|pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to 'true' [version 3.5.18+]|
|pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to 'true'|
Example in the configuration section:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<configuration>
<pact.showStacktrace>true</pact.showStacktrace>
</configuration>
</configuration>
</plugin>
```
## Provider States
For each provider you can specify a state change URL to use to switch the state of the provider. This URL will
receive the providerState description and parameters from the pact file before each interaction via a POST. The stateChangeUsesBody
controls if the state is passed in the request body or as query parameters.
These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChangeForConsumer1</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
If the `stateChangeUsesBody` is not specified, or is set to true, then the provider state description and parameters will be sent as
JSON in the body of the request. If it is set to false, they will passed as query parameters.
As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before
it is sent. Set `stateChangeRequestFilter` to a Groovy script on the provider that will be called before the request is made.
#### Teardown calls for state changes
You can enable teardown state change calls by setting the property `<stateChangeTeardown>true</stateChangeTeardown>` on the provider. This
will add an `action` parameter to the state change call. The setup call before the test will receive `action=setup`, and
then a teardown call will be made afterwards to the state change URL with `action=teardown`.
## Verifying pact files from a pact broker
You can setup your build to validate against the pacts stored in a pact broker. The pact plugin will query
the pact broker for all consumers that have a pact with the provider based on its name. To use it, just configure the
`pactBrokerUrl` or `pactBroker` value for the provider with the base URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBrokerUrl>http://pact-broker:5000/</pactBrokerUrl>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an authenticated pact broker
If your pact broker requires authentication (basic authentication is only supported), you can configure the username
and password to use by configuring the `authentication` element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<authentication>
<username>test</username>
<password>test</password>
</authentication>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
#### Using the Maven servers configuration [version 3.5.6+]
From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the
[Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker
configuration in your POM.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.6</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<serverId>test-pact-broker</serverId> <!-- This must match the server id in the maven settings -->
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an pact broker that match particular tags
If your pacts in your pact broker have been tagged, you can set the tags to fetch by configuring the `tags`
element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<tags>
<tag>TEST</tag>
<tag>DEV</tag>
</tags>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
This example will fetch and validate the pacts for the TEST and DEV tags.
## Filtering the interactions that are verified
You can filter the interactions that are run using three properties: `pact.filter.consumers`, `pact.filter.description` and `pact.filter.providerState`.
Adding `-Dpact.filter.consumers=consumer1,consumer2` to the command line or configuration section will only run the pact files for those
consumers (consumer1 and consumer2). Adding `-Dpact.filter.description=a request for payment.*` will only run those interactions
whose descriptions start with 'a request for payment'. `-Dpact.filter.providerState=.*payment` will match any interaction that
has a provider state that ends with payment, and `-Dpact.filter.providerState=` will match any interaction that does not have a
provider state.
## Not failing the build if no pact files are found [version 3.5.19+]
By default, if there are no pact files to verify, the plugin will raise an exception. This is to guard against false
positives where the build is passing but nothing has been verified due to mis-configuration.
To disable this behaviour, set the `failIfNoPactsFound` parameter to `false`.
# Verifying a message provider
The Maven plugin has been updated to allow invoking test methods that can return the message contents from a message
producer. To use it, set the way to invoke the verification to `ANNOTATED_METHOD`. This will allow the pact verification
task to scan for test methods that return the message contents.
Add something like the following to your maven pom file:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<!-- packagesToScan is optional, but leaving it out will result in the entire
test classpath being scanned. Set it to the packages where your annotated test method
can be found. -->
<packagesToScan>
<packageToScan>au.com.example.messageprovider.*</packageToScan>
</packagesToScan>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
Now when the pact verify task is run, will look for methods annotated with `@PactVerifyProvider` in the test classpath
that have a matching description to what is in the pact file.
```groovy
class ConfirmationKafkaMessageBuilderTest {
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setExchange('ASX')
order.setSecurityCode('CBA')
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
order.setGst(new BigDecimal('15.0'))
odrer.setFees(BigDecimal.TEN)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
It will then validate that the returned contents matches the contents for the message in the pact file.
## Changing the class path that is scanned
By default, the test classpath is scanned for annotated methods. You can override this by setting
the `classpathElements` property:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<classpathElements>
<classpathElement>
build/classes/test
</classpathElement>
</classpathElements>
</configuration>
</plugin>
```
# Publishing pact files to a pact broker
The pact maven plugin provides a `publish` mojo that can publish all pact files in a directory
to a pact broker. To use it, you need to add a publish configuration to the POM that defines the
directory where the pact files are and the URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<pactDirectory>path/to/pact/files</pactDirectory> <!-- Defaults to ${project.build.directory}/pacts -->
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<projectVersion>1.0.100</projectVersion> <!-- Defaults to ${project.version} -->
<trimSnapshot>true</trimSnapshot> <!-- Defaults to false -->
</configuration>
</plugin>
```
You can now execute `mvn pact:publish` to publish the pact files.
_NOTE:_ The pact broker requires a version for all published pacts. The `publish` task will use the version of the
project by default, but can be overwritten with the `projectVersion` property. Make sure you have set one otherwise the broker will reject the pact files.
_NOTE_: By default, the pact broker has issues parsing `SNAPSHOT` versions. You can configure the publisher to
automatically remove `-SNAPSHOT` from your version number by setting `trimSnapshot` to true. This setting does not modify non-snapshot versions.
You can set any tags that the pacts should be published with by setting the `tags` list property (version 3.5.12+). A common use of this
is setting the tag to the current source control branch. This supports using pact with feature branches.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.12</version>
<configuration>
<pactDirectory>path/to/pact/files</pactDirectory> <!-- Defaults to ${project.build.directory}/pacts -->
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<projectVersion>1.0.100</projectVersion> <!-- Defaults to ${project.version} -->
<tags>
<tag>feature/feature_name</tag>
</tags>
</configuration>
</plugin>
```
## Publishing to an authenticated pact broker
For an authenticated pact broker, you can pass in the credentials with the `pactBrokerUsername` and `pactBrokerPassword`
properties. Currently it only supports basic authentication.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerUsername>USERNAME</pactBrokerUsername>
<pactBrokerPassword>PASSWORD</pactBrokerPassword>
</configuration>
</plugin>
```
#### Using the Maven servers configuration [version 3.5.6+]
From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the
[Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker
configuration in your POM.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.5.19</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerServerId>test-pact-broker</pactBrokerServerId> <!-- This must match the server id in the maven settings -->
</configuration>
</plugin>
```
## Excluding pacts from being published [version 3.5.19+]
You can exclude some of the pact files from being published by providing a list of regular expressions that match
against the base names of the pact files.
For example:
```groovy
pact {
publish {
pactBrokerUrl = 'https://mypactbroker.com'
excludes = [ '.*\\-\\d+$' ] // exclude all pact files that end with a dash followed by a number in the name
}
}
```
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.19</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<excludes>
<exclude>.*\\-\\d+$</exclude> <!-- exclude pact files where the name ends in a dash followed by a number -->
</excludes>
</configuration>
</plugin>
```
# Publishing verification results to a Pact Broker [version 3.5.4+]
For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the
broker against the URL for the pact. You will be able to then see the result on the Pact Broker home screen.
To turn on the verification publishing, set the system property `pact.verifier.publishResults` to `true` in the pact maven plugin, not surefire, configuration.
# Enabling other verification reports [version 3.5.20+]
By default the verification report is written to the console. You can also enable a JSON or Markdown report by setting
the `reports` configuration list.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.20</version>
<configuration>
<reports>
<report>console</report>
<report>json</report>
<report>markdown</report>
</reports>
</configuration>
</plugin>
```
These reports will be written to `target/reports/pact`.

# Pact junit runner
## Overview
Library provides ability to play contract tests against a provider service in JUnit fashionable way.
Supports:
- Out-of-the-box convenient ways to load pacts
- Easy way to change assertion strategy
- **org.junit.BeforeClass**, **org.junit.AfterClass** and **org.junit.ClassRule** JUnit annotations, that will be run
once - before/after whole contract test suite.
- **org.junit.Before**, **org.junit.After** and **org.junit.Rule** JUnit annotations, that will be run before/after
each test of an interaction.
- **au.com.dius.pact.provider.junit.State** custom annotation - before each interaction that requires a state change,
all methods annotated by `@State` with appropriate the state listed will be invoked. These methods must either take
no parameters or a single Map parameter.
## Example of HTTP test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactFolder("pacts") // Point where to find pacts (See also section Pacts source in documentation)
public class ContractTest {
// NOTE: this is just an example of embedded service that listens to requests, you should start here real service
@ClassRule //Rule will be applied once: before/after whole contract test suite
public static final ClientDriverRule embeddedService = new ClientDriverRule(8332);
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Rest data
// Mock dependent service responses
// ...
embeddedService.addExpectation(
onRequestTo("/data"), giveEmptyResponse()
);
}
@State("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state
public void toDefaultState() {
// Prepare service before interaction that require "default" state
// ...
System.out.println("Now service in default state");
}
@State("with-data") // Method will be run before testing interactions that require "with-data" state
public void toStateWithData(Map data) {
// Prepare service before interaction that require "with-data" state. The provider state data will be passed
// in the data parameter
// ...
System.out.println("Now service in state using data " + data);
}
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new HttpTarget(8332); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
}
```
## Example of AMQP Message test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactBroker(host="pactbroker", port = "80")
public class ConfirmationKafkaContractTest {
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new AmqpTarget(); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Message data preparation
// ...
}
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
## Provider state callback methods
For the provider states in the pact being verified, you can define methods to be invoked to setup the correct state
for each interaction. Just annotate a method with the `au.com.dius.pact.provider.junit.State` annotation and the
method will be invoked before the interaction is verified.
For example:
```java
@State("SomeProviderState") // Must match the state description in the pact file
public void someProviderState() {
// Do what you need to set the correct state
}
```
If there are parameters in the pact file, just add a Map parameter to the method to be able to access those parameters.
```java
@State("SomeProviderState")
public void someProviderState(Map<String, Object> providerStateParameters) {
// Do what you need to set the correct state
}
```
### Provider state teardown methods [3.5.22+]
If you need to tear down your provider state, you can annotate a method with the `@State` annotation with the action
set to `StateChangeAction.TEARDOWN` and it will be invoked after the interaction is verified.
```java
@State("SomeProviderState", action = StateChangeAction.TEARDOWN)
public void someProviderStateCleanup() {
// Do what you need to to teardown the state
}
```
## Pact source
The Pact runner will automatically collect pacts based on annotations on the test class. For this purpose there are 3
out-of-the-box options (files from a directory, files from a set of URLs or a pact broker) or you can easily add your
own Pact source.
If you need to load a single pact file from the file system, use the `PactUrl` with the URL set to the file path.
**Note:** You can only define one source of pacts per test class.
### Download pacts from a pact-broker
To use pacts from a Pact Broker, annotate the test class with `@PactBroker(host="host.of.pact.broker.com", port = "80")`.
From _version 3.2.2/2.4.3+_ you can also specify the protocol, which defaults to "http".
The pact broker will be queried for all pacts with the same name as the provider annotation.
For example, test all pacts for the "Activity Service" in the pact broker:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@PactBroker(host = "localhost", port = "80")
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
#### _Version 3.2.3/2.4.4+_ - Using Java System properties
The pact broker loader was updated to allow system properties to be used for the hostname, port or protocol. The port
was changed to a string to allow expressions to be set.
To use a system property or environment variable, you can place the property name in `${}` expression de-markers:
```java
@PactBroker(host="${pactbroker.hostname}", port = "80")
```
You can provide a default value by separating the property name with a colon (`:`):
```java
@PactBroker(host="${pactbroker.hostname:localhost}", port = "80")
```
#### _Version 3.5.3+_ - More Java System properties
The default values of the `@PactBroker` annotation now enable variable interpolation.
The following keys may be managed through the environment
* `pactbroker.host`
* `pactbroker.port`
* `pactbroker.protocol`
* `pactbroker.tags` (comma separated)
* `pactbroker.auth.scheme`
* `pactbroker.auth.username`
* `pactbroker.auth.password`
#### _Version 3.2.4/2.4.6+_ - Using tags with the pact broker
The pact broker allows different versions to be tagged. To load all the pacts:
```java
@PactBroker(host="pactbroker", port = "80", tags = {"latest", "dev", "prod"})
```
The default value for tags is `latest` which is not actually a tag but instead corresponds to the latest version ignoring the tags. If there are multiple consumers matching the name specified in the provider annotation then the latest pact for each of the consumers is loaded.
For any other value the latest pact tagged with the specified tag is loaded.
Specifying multiple tags is an OR operation. For example if you specify `tags = {"dev", "prod"}` then both the latest pact file tagged with `dev` and the latest pact file taggged with `prod` is loaded.
#### _Version 3.3.4/2.4.19+_ - Using basic auth with the with the pact broker
You can use basic authentication with the `@PactBroker` annotation by setting the `authentication` value to a `@PactBrokerAuth`
annotation. For example:
```java
@PactBroker(host = "${pactbroker.url:localhost}", port = "1234", tags = {"latest", "prod", "dev"},
authentication = @PactBrokerAuth(username = "test", password = "test"))
```
The `username` and `password` values also take Java system property expressions.
### Pact Url
To use pacts from urls annotate the test class with
```java
@PactUrl(urls = {"http://build.server/zoo_app-animal_service.json"} )
```
If you need to load a single pact file from the file system, you can use the `PactUrl` with the URL set to the file path.
### Pact folder
To use pacts from a resource folder of the project annotate test class with
```java
@PactFolder("subfolder/in/resource/directory")
```
### Custom pacts source
It's possible to use a custom Pact source. For this, implement interface `au.com.dius.pact.provider.junit.loader.PactLoader`
and annotate the test class with `@PactSource(MyOwnPactLoader.class)`. **Note:** class `MyOwnPactLoader` must have a default empty constructor or a constructor with one argument of class `Class` which at runtime will be the test class so you can get custom annotations of test class.
### Filtering the interactions that are verified [version 3.5.3+]
By default, the pact runner will verify all pacts for the given provider. You can filter the pacts and interactions by
the following methods.
#### Filtering by Consumer
You can run only those pacts for a particular consumer by adding a `@Consumer` annotation to the test class.
For example:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@Consumer("Activity Consumer")
@PactBroker(host = "localhost", port = "80")
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
#### Filtering by Provider State
You can filter the interactions that are executed by adding a `@PactFilter` annotation to your test class. The pact
filter annotation will then only verify interactions that have a matching provider state. You can provide multiple
states to match with.
For example:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@PactBroker(host = "localhost", port = "80")
@PactFilter('Activity 100 exists in the database')
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
You can also use regular expressions with the filter [version 3.5.3+]. For example:
```java
@RunWith(PactRunner.class)
@PactFilter('Activity \\d+ exists in the database')
public class PactJUnitTest {
}
```
### Setting the test to not fail when no pacts are found [version 3.5.3+]
By default the pact runner will fail the verification test if no pact files are found to verify. To change the
failure into a warning, add a `@IgnoreNoPactsToVerify` annotation to your test class.
#### Ignoring IO errors loading pact files [version 3.5.24+]
You can also set the test to ignore any IO and parser exceptions when loading the pact files by setting the
`ignoreIoErrors` attribute on the annotation to `"true"` or setting the JVM system property `pact.verification.ignoreIoErrors`
to `true`.
** WARNING! Do not enable this on your CI server, as this could result in your build passing with no providers
having been verified due to a configuration error. **
## Test target
The field in test class of type `au.com.dius.pact.provider.junit.target.Target` annotated with `au.com.dius.pact.provider.junit.target.TestTarget`
will be used for actual Interaction execution and asserting of contract.
**Note:** there must be exactly 1 such field, otherwise an `InitializationException` will be thrown.
### HttpTarget
`au.com.dius.pact.provider.junit.target.HttpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as http request and assert response from service by matching rules from pact.
_Version 3.2.2/2.4.3+_ you can also specify the protocol, defaults to "http".
### AmqpTarget
`au.com.dius.pact.provider.junit.target.AmqpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as an AMQP message and assert response from service by matching rules from pact.
#### Modifying the requests before they are sent [Version 3.2.3/2.4.5+]
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The HttpTarget supports request filters by annotating methods
on the test class with `@TargetRequestFilter`. These methods must be public void methods that take a single HttpRequest
parameter.
For example:
```java
@TargetRequestFilter
public void exampleRequestFilter(HttpRequest request) {
request.addHeader("Authorization", "OAUTH hdsagasjhgdjashgdah...");
}
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
#### Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
### Custom Test Target
It's possible to use custom `Target`, for that interface `Target` should be implemented and this class can be used instead of `HttpTarget`.
# Verification Reports [versions 3.2.7/2.4.9+]
The default test behaviour is to display the verification being done to the console, and pass or fail the test via the normal
JUnit mechanism. From versions 3.2.7/2.4.9+, additional reports can be generated from the tests.
## Enabling additional reports via annotations on the test classes
A `@VerificationReports` annotation can be added to any pact test class which will control the verification output. The
annotation takes a list report types and an optional report directory (defaults to "target/pact/reports").
The currently supported report types are `console`, `markdown` and `json`.
For example:
```java
@VerificationReports({"console", "markdown"})
public class MyPactTest {
```
will enable the markdown report in addition to the normal console output. And,
```java
@VerificationReports(value = {"markdown"}, reportDir = "/myreports")
public class MyPactTest {
```
will disable the normal console output and write the markdown reports to "/myreports".
## Enabling additional reports via Java system properties or environment variables
The additional reports can also be enabled with Java System properties or environment variables. The following two
properties have been introduced: `pact.verification.reports` and `pact.verification.reportDir`.
`pact.verification.reports` is the comma separated list of report types to enable (e.g. `console,json,markdown`).
`pact.verification.reportDir` is the directory to write reports to (defaults to "target/pact/reports").
## Additional Reports
The following report types are available in addition to console output (`console`, which is enabled by default):
`markdown`, `json`.
You can also provide a fully qualified classname as report so custom reports are also supported.
This class must implement `au.com.dius.pact.provider.reporters.VerifierReporter` interface in order to be correct custom implementation of a report.
# Publishing verification results to a Pact Broker [version 3.5.4+]
For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the
broker against the URL for the pact. You will be able to see the result on the Pact Broker home screen. You need to
set the version of the provider that is verified using the `pact.provider.version` system property.
To enable publishing of results, set the property `pact.verifier.publishResults` to `true` [version 3.5.18+].

pact-jvm-provider-maven_2.10 from group au.com.dius (version 2.4.20)
Maven plugin to verify a provider [version 2.1.9+]
==================================================
Maven plugin for verifying pacts against a provider.
The Maven plugin provides a `verify` goal which will verify all configured pacts against your provider.
## To Use It
### 1. Add the pact-jvm-provider-maven plugin to your `build` section of your pom file.
```xml
<build>
[...]
<plugins>
[...]
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
</plugin>
[...]
</plugins>
[...]
</build>
```
### 2. Define the pacts between your consumers and providers
You define all the providers and consumers within the configuration element of the maven plugin.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<consumers>
<!-- Again, you can define as many consumers for each provider as you need, but each must have a unique name -->
<consumer>
<name>consumer1</name>
<!-- currently supports a file path using pactFile or a URL using pactUrl -->
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### 3. Execute `mvn pact:verify`
You will have to have your provider running for this to pass.
## Verifying all pact files in a directory for a provider. [2.1.10+]
You can specify a directory that contains pact files, and the Pact plugin will scan for all pact files that match that
provider and define a consumer for each pact file in the directory. Consumer name is read from contents of pact file.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Enabling insecure SSL [version 2.2.8+]
For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting
`<insecure>true</insecure>` on the provider.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<insecure>true</insecure>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Specifying a custom trust store [version 2.2.8+]
For environments that are running their own certificate chains:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<trustStore>relative/path/to/trustStore.jks</trustStore>
<trustStorePassword>changeit</trustStorePassword>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
`trustStore` is either relative to the current working (build) directory. `trustStorePassword` defaults to `changeit`.
NOTE: The hostname will still be verified against the certificate.
## Modifying the requests before they are sent
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The Pact Maven plugin provides a request filter that can be
set to a Groovy script on the provider that will be called before the request is made. This script will receive the HttpRequest
bound to a variable named `request` prior to it being executed.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<requestFilter>
// This is a Groovy script that adds an Authorization header to each request
request.addHeader('Authorization', 'oauth-token eyJhbGciOiJSUzI1NiIsIm...')
</requestFilter>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
## Modifying the HTTP Client Used [version 2.2.4+]
The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`).
This can be changed by specifying a closure assigned to createClient on the provider that returns a CloseableHttpClient.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<createClient>
// This is a Groovy script that will enable the client to accept self-signed certificates
import org.apache.http.ssl.SSLContextBuilder
import org.apache.http.conn.ssl.NoopHostnameVerifier
import org.apache.http.impl.client.HttpClients
HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier())
.setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, { x509Certificates, s -> true })
.build())
.build()
</createClient>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
## Plugin Properties
The following plugin properties can be specified with `-Dproperty=value` on the command line or in the configuration section:
|Property|Description|
|--------|-----------|
|pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors|
|pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies [version 3.3.6+]|
|pact.filter.consumers|Comma seperated list of consumer names to verify|
|pact.filter.description|Only verify interactions whose description match the provided regular expression|
|pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state|
Example in the configuration section:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<configuration>
<pact.showStacktrace>true</pact.showStacktrace>
</configuration>
</configuration>
</plugin>
```
## Provider States
For each provider you can specify a state change URL to use to switch the state of the provider. This URL will
receive the providerState description from the pact file before each interaction via a POST. The stateChangeUsesBody
controls if the state is passed in the request body or as a query parameter.
These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChangeForConsumer1</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
If the `stateChangeUsesBody` is not specified, or is set to true, then the provider state description will be sent as
JSON in the body of the request. If it is set to false, it will passed as a query parameter.
As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before
it is sent. Set `stateChangeRequestFilter` to a Groovy script on the provider that will be called before the request is made.
#### Teardown calls for state changes [version 3.2.5/2.4.7+]
You can enable teardown state change calls by setting the property `<stateChangeTeardown>true</stateChangeTeardown>` on the provider. This
will add an `action` parameter to the state change call. The setup call before the test will receive `action=setup`, and
then a teardown call will be made afterwards to the state change URL with `action=teardown`.
## Verifying pact files from a pact broker [version 3.1.1+/2.3.1+]
You can setup your build to validate against the pacts stored in a pact broker. The pact plugin will query
the pact broker for all consumers that have a pact with the provider based on its name. To use it, just configure the
`pactBrokerUrl` or `pactBroker` value for the provider with the base URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBrokerUrl>http://pact-broker:5000/</pactBrokerUrl>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an authenticated pact broker [version 3.3.5+]
If your pact broker requires authentication (basic authentication is only supported), you can configure the username
and password to use by configuring the `authentication` element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<authentication>
<username>test</username>
<password>test</password>
</authentication>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an pact broker that match particular tags [version 3.3.5+]
If your pacts in your pact broker have been tagged, you can set the tags to fetch by configuring the `tags`
element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<tags>
<tag>TEST</tag>
<tag>DEV</tag>
</tags>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
This example will fetch and validate the pacts for the TEST and DEV tags.
## Filtering the interactions that are verified
You can filter the interactions that are run using three properties: `pact.filter.consumers`, `pact.filter.description` and `pact.filter.providerState`.
Adding `-Dpact.filter.consumers=consumer1,consumer2` to the command line or configuration section will only run the pact files for those
consumers (consumer1 and consumer2). Adding `-Dpact.filter.description=a request for payment.*` will only run those interactions
whose descriptions start with 'a request for payment'. `-Dpact.filter.providerState=.*payment` will match any interaction that
has a provider state that ends with payment, and `-Dpact.filter.providerState=` will match any interaction that does not have a
provider state.
# Verifying a message provider [version 2.2.12+]
The Maven plugin has been updated to allow invoking test methods that can return the message contents from a message
producer. To use it, set the way to invoke the verification to `ANNOTATED_METHOD`. This will allow the pact verification
task to scan for test methods that return the message contents.
Add something like the following to your maven pom file:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<!-- packagesToScan is optional, but leaving it out will result in the entire
test classpath being scanned. Set it to the packages where your annotated test method
can be found. -->
<packagesToScan>
<packageToScan>au.com.example.messageprovider.*</packageToScan>
</packagesToScan>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
Now when the pact verify task is run, will look for methods annotated with `@PactVerifyProvider` in the test classpath
that have a matching description to what is in the pact file.
```groovy
class ConfirmationKafkaMessageBuilderTest {
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setExchange('ASX')
order.setSecurityCode('CBA')
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
order.setGst(new BigDecimal('15.0'))
odrer.setFees(BigDecimal.TEN)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
It will then validate that the returned contents matches the contents for the message in the pact file.
## Changing the class path that is scanned
By default, the test classpath is scanned for annotated methods. You can override this by setting
the `classpathElements` property:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<classpathElements>
<classpathElement>
build/classes/test
</classpathElement>
</classpathElements>
</configuration>
</plugin>
```
# Publishing pact files to a pact broker [version 3.2.0+]
The pact maven plugin provides a `publish` mojo that can publish all pact files in a directory
to a pact broker. To use it, you need to add a publish configuration to the POM that defines the
directory where the pact files are and the URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.8</version>
<configuration>
<pactDirectory>path/to/pact/files</pactDirectory> <!-- Defaults to ${project.build.directory}/pacts -->
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<projectVersion>1.0.100</projectVersion> <!-- Defaults to ${project.version} -->
<trimSnapshot>true</trimSnapshot> <!-- Defaults to false -->
</configuration>
</plugin>
```
You can now execute `mvn pact:publish` to publish the pact files.
_NOTE:_ The pact broker requires a version for all published pacts. The `publish` task will use the version of the
project by default, but can be overwritten with the `projectVersion` property. Make sure you have set one otherwise the broker will reject the pact files.
_NOTE_: By default, the pact broker has issues parsing `SNAPSHOT` versions. You can configure the publisher to automatically remove `-SNAPSHOT` from your version number by setting `trimSnapshot` to true. This setting does not modify non-snapshot versions.
## Publishing to an authenticated pact broker [version 3.3.9+]
For an authenticated pact broker, you can pass in the credentials with the `pactBrokerUsername` and `pactBrokerPassword`
properties. Currently it only supports basic authentication.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.3.9</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerUsername>USERNAME</pactBrokerUsername>
<pactBrokerPassword>PASSWORD</pactBrokerPassword>
</configuration>
</plugin>
```

# Pact junit runner
## Overview
Library provides ability to play contract tests against a provider service in JUnit fashionable way.
Supports:
- Out-of-the-box convenient ways to load pacts
- Easy way to change assertion strategy
- **org.junit.BeforeClass**, **org.junit.AfterClass** and **org.junit.ClassRule** JUnit annotations, that will be run
once - before/after whole contract test suite.
- **org.junit.Before**, **org.junit.After** and **org.junit.Rule** JUnit annotations, that will be run before/after
each test of an interaction.
- **au.com.dius.pact.provider.junit.State** custom annotation - before each interaction that requires a state change,
all methods annotated by `@State` with appropriate the state listed will be invoked.
## Example of HTTP test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactFolder("pacts") // Point where to find pacts (See also section Pacts source in documentation)
public class ContractTest {
// NOTE: this is just an example of embedded service that listens to requests, you should start here real service
@ClassRule //Rule will be applied once: before/after whole contract test suite
public static final ClientDriverRule embeddedService = new ClientDriverRule(8332);
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Rest data
// Mock dependent service responses
// ...
embeddedService.addExpectation(
onRequestTo("/data"), giveEmptyResponse()
);
}
@State("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state
public void toDefaultState() {
// Prepare service before interaction that require "default" state
// ...
System.out.println("Now service in default state");
}
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new HttpTarget(8332); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
}
```
## Example of AMQP Message test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactBroker(host="pactbroker", port = "80")
public class ConfirmationKafkaContractTest {
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new AmqpTarget(); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Message data preparation
// ...
}
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)

## Pact source
The Pact runner will automatically collect pacts based on annotations on the test class. For this purpose there are 3
out-of-the-box options (files from a directory, files from a set of URLs or a pact broker) or you can easily add your
own Pact source.
**Note:** You can only define one source of pacts per test class.
### Download pacts from a pact-broker
To use pacts from a Pact Broker, annotate the test class with `@PactBroker(host="host.of.pact.broker.com", port = "80")`.
From _version 3.2.2/2.4.3+_ you can also specify the protocol, which defaults to "http".
The pact broker will be queried for all pacts with the same name as the provider annotation.
For example, test all pacts for the "Activity Service" in the pact broker:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@PactBroker(host = "localhost", port = "80")
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
#### _Version 3.2.3/2.4.4+_ - Using Java System properties
The pact broker loader was updated to allow system properties to be used for the hostname, port or protocol. The port
was changed to a string to allow expressions to be set.
To use a system property or environment variable, you can place the property name in `${}` expression de-markers:
```java
@PactBroker(host="${pactbroker.hostname}", port = "80")
```
You can provide a default value by separating the property name with a colon (`:`):
```java
@PactBroker(host="${pactbroker.hostname:localhost}", port = "80")
```
#### _Version ???/???+_ - More Java System properties
The default values of the `@PactBroker` annotation now enable variable interpolation.
The following keys may be managed through the environment
* `pactbroker.host`
* `pactbroker.port`
* `pactbroker.protocol`
* `pactbroker.tags` (comma separated)
* `pactbroker.auth.scheme`
* `pactbroker.auth.username`
* `pactbroker.auth.password`
#### _Version 3.2.4/2.4.6+_ - Using tags with the pact broker
The pact broker allows different versions to be tagged. To load all the pacts:
```java
@PactBroker(host="pactbroker", port = "80", tags = {"latest", "dev", "prod"})
```
The default value for tags is `latest` which is not actually a tag but instead corresponds to the latest version ignoring the tags. If there are multiple consumers matching the name specified in the provider annotation then the latest pact for each of the consumers is loaded.
For any other value the latest pact tagged with the specified tag is loaded.
Specifying multiple tags is an OR operation. For example if you specify `tags = {"dev", "prod"}` then both the latest pact file tagged with `dev` and the latest pact file taggged with `prod` is loaded.
#### _Version 3.3.4/2.4.19+_ - Using basic auth with the with the pact broker
You can use basic authentication with the `@PactBroker` annotation by setting the `authentication` value to a `@PactBrokerAuth`
annotation. For example:
```java
@PactBroker(host = "${pactbroker.url:localhost}", port = "1234", tags = {"latest", "prod", "dev"},
authentication = @PactBrokerAuth(username = "test", password = "test"))
```
The `username` and `password` values also take Java system property expressions.
### Pact Url
To use pacts from urls annotate the test class with
```java
@PactUrl(urls = {"http://build.server/zoo_app-animal_service.json"} )
```
### Pact folder
To use pacts from a resource folder of the project annotate test class with
```java
@PactFolder("subfolder/in/resource/directory")
```
### Custom pacts source
It's possible to use a custom Pact source. For this, implement interface `au.com.dius.pact.provider.junit.loader.PactLoader`
and annotate the test class with `@PactSource(MyOwnPactLoader.class)`. **Note:** class `MyOwnPactLoader` must have a default empty constructor or a constructor with one argument of class `Class` which at runtime will be the test class so you can get custom annotations of test class.
## Test target
The field in test class of type `au.com.dius.pact.provider.junit.target.Target` annotated with `au.com.dius.pact.provider.junit.target.TestTarget`
will be used for actual Interaction execution and asserting of contract.
**Note:** there must be exactly 1 such field, otherwise an `InitializationException` will be thrown.
### HttpTarget
`au.com.dius.pact.provider.junit.target.HttpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as http request and assert response from service by matching rules from pact.
_Version 3.2.2/2.4.3+_ you can also specify the protocol, defaults to "http".
### AmqpTarget
`au.com.dius.pact.provider.junit.target.AmqpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as an AMQP message and assert response from service by matching rules from pact.
#### Modifying the requests before they are sent [Version 3.2.3/2.4.5+]
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The HttpTarget supports request filters by annotating methods
on the test class with `@TargetRequestFilter`. These methods must be public void methods that take a single HttpRequest
parameter.
For example:
```java
@TargetRequestFilter
public void exampleRequestFilter(HttpRequest request) {
request.addHeader("Authorization", "OAUTH hdsagasjhgdjashgdah...");
}
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
#### Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
### Custom Test Target
It's possible to use custom `Target`, for that interface `Target` should be implemented and this class can be used instead of `HttpTarget`.
# Verification Reports [versions 3.2.7/2.4.9+]
The default test behaviour is to display the verification being done to the console, and pass or fail the test via the normal
JUnit mechanism. From versions 3.2.7/2.4.9+, additional reports can be generated from the tests.
## Enabling additional reports via annotations on the test classes
A `@VerificationReports` annotation can be added to any pact test class which will control the verification output. The
annotation takes a list report types and an optional report directory (defaults to "target/pact/reports").
The currently supported report types are `console`, `markdown` and `json`.
For example:
```java
@VerificationReports({"console", "markdown"})
public class MyPactTest {
```
will enable the markdown report in addition to the normal console output. And,
```java
@VerificationReports(value = {"markdown"}, reportDir = "/myreports")
public class MyPactTest {
```
will disable the normal console output and write the markdown reports to "/myreports".
## Enabling additional reports via Java system properties or environment variables
The additional reports can also be enabled with Java System properties or environment variables. The following two
properties have been introduced: `pact.verification.reports` and `pact.verification.reportDir`.
`pact.verification.reports` is the comma separated list of report types to enable (e.g. `console,json,markdown`).
`pact.verification.reportDir` is the directory to write reports to (defaults to "target/pact/reports").
## Additional Reports
The following report types are available in addition to console output (`console`, which is enabled by default):
`markdown`, `json`.
You can also provide a fully qualified classname as report so custom reports are also supported.
This class must implement `au.com.dius.pact.provider.reporters.VerifierReporter` interface in order to be correct custom implementation of a report.

pact-jvm-consumer-groovy_2.10 from group au.com.dius (version 2.4.20)
pact-jvm-consumer-groovy
=========================
Groovy DSL for Pact JVM
## Dependency
The library is available on maven central using:
* group-id = `au.com.dius`
* artifact-id = `pact-jvm-consumer-groovy_2.11`
* version-id = `2.4.x` or `3.2.x`
## Usage
Add the `pact-jvm-consumer-groovy` library to your test class path. This provides a `PactBuilder` class for you to use
to define your pacts. For a full example, have a look at the example JUnit `ExampleGroovyConsumerPactTest`.
If you are using gradle for your build, add it to your `build.gradle`:
dependencies {
testCompile 'au.com.dius:pact-jvm-consumer-groovy_2.11:3.2.14'
}
Then create an instance of the `PactBuilder` in your test.
```groovy
@Test
void "A service consumer side of a pact goes a little something like this"() {
def alice_service = new PactBuilder() // Create a new PactBuilder
alice_service {
serviceConsumer "Consumer" // Define the service consumer by name
hasPactWith "Alice Service" // Define the service provider that it has a pact with
port 1234 // The port number for the service. It is optional, leave it out to
// to use a random one
given('there is some good mallory') // defines a provider state. It is optional.
uponReceiving('a retrieve Mallory request') // upon_receiving starts a new interaction
withAttributes(method: 'get', path: '/mallory') // define the request, a GET request to '/mallory'
willRespondWith( // define the response we want returned
status: 200,
headers: ['Content-Type': 'text/html'],
body: '"That is some good Mallory."'
)
}
// Execute the run method to have the mock server run.
// It takes a closure to execute your requests and returns a Pact VerificationResult.
VerificationResult result = alice_service.run() {
def client = new RESTClient('http://localhost:1234/')
def alice_response = client.get(path: '/mallory')
assert alice_response.status == 200
assert alice_response.contentType == 'text/html'
def data = alice_response.data.text()
assert data == '"That is some good Mallory."'
}
assert result == PactVerified$.MODULE$ // This means it is all good in weird Scala speak.
}
```
After running this test, the following pact file is produced:
{
"provider" : {
"name" : "Alice Service"
},
"consumer" : {
"name" : "Consumer"
},
"interactions" : [ {
"provider_state" : "there is some good mallory",
"description" : "a retrieve Mallory request",
"request" : {
"method" : "get",
"path" : "/mallory",
"requestMatchers" : { }
},
"response" : {
"status" : 200,
"headers" : {
"Content-Type" : "text/html"
},
"body" : "That is some good Mallory.",
"responseMatchers" : { }
}
} ]
}
### DSL Methods
#### serviceConsumer(String consumer)
This names the service consumer for the pact.
#### hasPactWith(String provider)
This names the service provider for the pact.
#### port(int port)
Sets the port that the mock server will run on. If not supplied, a random port will be used.
#### given(String providerState)
Defines a state that the provider needs to be in for the request to succeed. For more info, see
https://github.com/realestate-com-au/pact/wiki/Provider-states
#### uponReceiving(String requestDescription)
Starts the definition of a of a pact interaction.
#### withAttributes(Map requestData)
Defines the request for the interaction. The request data map can contain the following:
| key | Description | Default Value |
|----------------------------|-------------------------------------------|-----------------------------|
| method | The HTTP method to use | get |
| path | The Path for the request | / |
| query | Query parameters as a Map<String, List> | |
| headers | Map of key-value pairs for the request headers | |
| body | The body of the request. If it is not a string, it will be converted to JSON. Also accepts a PactBodyBuilder. | |
| prettyPrint | Boolean value to control if the body is pretty printed. See note on Pretty Printed Bodies below |
For the path, header attributes and query parameters (version 2.2.2+ for headers, 3.3.7+ for query parameters),
you can use regular expressions to match. You can either provide a regex `Pattern` class or use the `regexp` method
to construct a `RegexpMatcher` (you can use any of the defined matcher methods, see DSL methods below).
If you use a `Pattern`, or the `regexp` method but don't provide a value, a random one will be generated from the
regular expression. This value is used when generating requests.
For example:
```groovy
.withAttributes(path: ~'/transaction/[0-9]+') // This will generate a random path for requests
// or
.withAttributes(path: regexp('/transaction/[0-9]+', '/transaction/1234567890'))
```
#### withBody(Closure closure)
Constructs the body of the request or response by invoking the supplied closure in the context of a PactBodyBuilder.
##### Pretty Printed Bodies [Version 2.2.15+, 3.0.4+]
An optional Map can be supplied to control how the body is generated. The option values are available:
| Option | Description |
|--------|-------------|
| mimeType | The mime type of the body. Defaults to `application/json` |
| prettyPrint | Boolean value controlling whether to pretty-print the body or not. Defaults to true |
If the prettyPrint option is not specified, the bodies will be pretty printed unless the mime type corresponds to one
that requires compact bodies. Currently only `application/x-thrift+json` is classed as requiring a compact body.
For an example of turning off pretty printing:
```groovy
service {
uponReceiving('a request')
withAttributes(method: 'get', path: '/')
withBody(prettyPrint: false) {
name 'harry'
surname 'larry'
}
}
```
#### willRespondWith(Map responseData)
Defines the response for the interaction. The response data map can contain the following:
| key | Description | Default Value |
|----------------------------|-------------------------------------------|-----------------------------|
| status | The HTTP status code to return | 200 |
| headers | Map of key-value pairs for the response headers | |
| body | The body of the response. If it is not a string, it will be converted to JSON. Also accepts a PactBodyBuilder. | |
| prettyPrint | Boolean value to control if the body is pretty printed. See note on Pretty Printed Bodies above |
For the headers (version 2.2.2+), you can use regular expressions to match. You can either provide a regex `Pattern` class or use
the `regexp` method to construct a `RegexpMatcher` (you can use any of the defined matcher methods, see DSL methods below).
If you use a `Pattern`, or the `regexp` method but don't provide a value, a random one will be generated from the
regular expression. This value is used when generating responses.
For example:
```groovy
.willRespondWith(headers: [LOCATION: ~'/transaction/[0-9]+']) // This will generate a random location value
// or
.willRespondWith(headers: [LOCATION: regexp('/transaction/[0-9]+', '/transaction/1234567890')])
```
#### VerificationResult run(Closure closure)
The `run` method starts the mock server, and then executes the provided closure. It then returns the pact verification
result for the pact run. If you require access to the mock server configuration for the URL, it is passed into the
closure, e.g.,
```groovy
VerificationResult result = alice_service.run() { config ->
def client = new RESTClient(config.url())
def alice_response = client.get(path: '/mallory')
}
```
### Body DSL
For building JSON bodies there is a `PactBodyBuilder` that provides as DSL that includes matching with regular expressions
and by types. For a more complete example look at `PactBodyBuilderTest`.
For an example:
```groovy
service {
uponReceiving('a request')
withAttributes(method: 'get', path: '/')
withBody {
name(~/\w+/, 'harry')
surname regexp(~/\w+/, 'larry')
position regexp(~/staff|contractor/, 'staff')
happy(true)
}
}
```
This will return the following body:
```json
{
"name": "harry",
"surname": "larry",
"position": "staff",
"happy": true
}
```
and add the following matchers:
```json
{
"$.body.name": {"regex": "\\w+"},
"$.body.surname": {"regex": "\\w+"},
"$.body.position": {"regex": "staff|contractor"}
}
```
#### DSL Methods
The DSL supports the following matching methods:
* regexp(Pattern re, String value = null), regexp(String regexp, String value = null)
Defines a regular expression matcher. If the value is not provided, a random one will be generated.
* hexValue(String value = null)
Defines a matcher that accepts hexidecimal values. If the value is not provided, a random hexidcimal value will be
generated.
* identifier(def value = null)
Defines a matcher that accepts integer values. If the value is not provided, a random value will be generated.
* ipAddress(String value = null)
Defines a matcher that accepts IP addresses. If the value is not provided, a 127.0.0.1 will be used.
* numeric(Number value = null)
Defines a matcher that accepts any numerical values. If the value is not provided, a random integer will be used.
* integer(def value = null)
Defines a matcher that accepts any integer values. If the value is not provided, a random integer will be used.
* real(def value = null)
Defines a matcher that accepts any real numbers. If the value is not provided, a random double will be used.
* timestamp(String pattern = null, def value = null)
If pattern is not provided the ISO_DATETIME_FORMAT is used ("yyyy-MM-dd'T'HH:mm:ss") . If the value is not provided, the current date and time is used.
* time(String pattern = null, def value = null)
If pattern is not provided the ISO_TIME_FORMAT is used ("'T'HH:mm:ss") . If the value is not provided, the current date and time is used.
* date(String pattern = null, def value = null)
If pattern is not provided the ISO_DATE_FORMAT is used ("yyyy-MM-dd") . If the value is not provided, the current date and time is used.
* uuid(String value = null)
Defines a matcher that accepts UUIDs. A random one will be generated if no value is provided.
#### What if a field matches a matcher name in the DSL?
When using the body DSL, if there is a field that matches a matcher name (e.g. a field named 'date') then you can do the following:
```groovy
withBody {
date = date()
}
```
### Ensuring all items in a list match an example (2.2.0+)
Lots of the time you might not know the number of items that will be in a list, but you want to ensure that the list
has a minimum or maximum size and that each item in the list matches a given example. You can do this with the `eachLike`,
`minLike` and `maxLike` functions.
| function | description |
|----------|-------------|
| `eachLike()` | Ensure that each item in the list matches the provided example |
| `maxLike(integer max)` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `minLike(integer min)` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```groovy
withBody {
users minLike(1) {
id identifier
name string('Fred')
}
}
```
This will ensure that the user list is never empty and that each user has an identifier that is a number and a name that is a string.
__Version 3.2.4/2.4.6+__ You can specify the number of example items to generate in the array. The default is 1.
```groovy
withBody {
users minLike(1, 3) {
id identifier
name string('Fred')
}
}
```
This will create an example user list with 3 users.
__Version 3.2.13/2.4.14+__ The each like matchers have been updated to work with primitive types.
```groovy
withBody {
permissions eachLike(3, 'GRANT')
}
```
will generate the following JSON
```json
{
"permissions": ["GRANT", "GRANT", "GRANT"]
}
```
and matchers
```json
{
"$.body.permissions": {"match": "type"}
}
```
and now you can even get more fancy
```groovy
withBody {
permissions eachLike(3, regexp(~/\w+/))
permissions2 minLike(2, 3, integer())
permissions3 maxLike(4, 3, ~/\d+/)
}
```
### Matching any key in a map (3.3.1/2.5.0+)
The DSL has been extended for cases where the keys in a map are IDs. For an example of this, see
[#313](https://github.com/DiUS/pact-jvm/issues/131). In this case you can use the `keyLike` method, which takes an
example key as a parameter.
For example:
```groovy
withBody {
example {
one {
keyLike '001', 'value' // key like an id mapped to a value
}
two {
keyLike 'ABC001', regexp('\\w+') // key like an id mapped to a matcher
}
three {
keyLike 'XYZ001', { // key like an id mapped to a closure
id identifier()
}
}
four {
keyLike '001XYZ', eachLike { // key like an id mapped to an array where each item is matched by the following
id identifier() // example
}
}
}
}
```
For an example, have a look at [WildcardPactSpec](src/test/au/com/dius/pact/consumer/groovy/WildcardPactSpec.groovy).
**NOTE:** The `keyLike` method adds a `*` to the matching path, so the matching definition will be applied to all keys
of the map if there is not a more specific matcher defined for a particular key. Having more than one `keyLike` condition
applied to a map will result in only one being applied when the pact is verified (probably the last).
## Changing the directory pact files are written to (2.1.9+)
By default, pact files are written to `target/pacts`, but this can be overwritten with the `pact.rootDir` system property.
This property needs to be set on the test JVM as most build tools will fork a new JVM to run the tests.
For Gradle, add this to your build.gradle:
```groovy
test {
systemProperties['pact.rootDir'] = "$buildDir/pacts"
}
```
# Publishing your pact files to a pact broker
If you use Gradle, you can use the [pact Gradle plugin](https://github.com/DiUS/pact-jvm/tree/master/pact-jvm-provider-gradle#publishing-pact-files-to-a-pact-broker) to publish your pact files.
# Pact Specification V3
Version 3 of the pact specification changes the format of pact files in the following ways:
* Query parameters are stored in a map form and are un-encoded (see [#66](https://github.com/DiUS/pact-jvm/issues/66)
and [#97](https://github.com/DiUS/pact-jvm/issues/97) for information on what this can cause).
* Introduces a new message pact format for testing interactions via a message queue.
## Generating V3 spec pact files (3.1.0+, 2.3.0+)
To have your consumer tests generate V3 format pacts, you can pass an option into the `run` method. For example:
```groovy
VerificationResult result = service.run(specificationVersion: PactSpecVersion.V3) { config ->
def client = new RESTClient(config.url())
def response = client.get(path: '/')
}
```
## Consumer test for a message consumer
For testing a consumer of messages from a message queue, the `PactMessageBuilder` class provides a DSL for defining
your message expectations. It works in much the same way as the `PactBuilder` class for Request-Response interactions,
but will generate a V3 format message pact file.
The following steps demonstrate how to use it.
### Step 1 - define the message expectations
Create a test that uses the `PactMessageBuilder` to define a message expectation, and then call `run`. This will invoke
the given closure with a message for each one defined in the pact.
```groovy
def eventStream = new PactMessageBuilder().call {
serviceConsumer 'messageConsumer'
hasPactWith 'messageProducer'
given 'order with id 10000004 exists'
expectsToReceive 'an order confirmation message'
withMetaData(type: 'OrderConfirmed') // Can define any key-value pairs here
withContent(contentType: 'application/json') {
type 'OrderConfirmed'
audit {
userCode 'messageService'
}
origin 'message-service'
referenceId '10000004-2'
timeSent: '2015-07-22T10:14:28+00:00'
value {
orderId '10000004'
value '10.000000'
fee '10.00'
gst '15.00'
}
}
}
```
### Step 2 - call your message handler with the generated messages
This example tests a message handler that gets messages from a Kafka topic. In this case the Pact message is wrapped
as a Kafka `MessageAndMetadata`.
```groovy
eventStream.run { Message message ->
messageHandler.handleMessage(new MessageAndMetadata('topic', 1,
new kafka.message.Message(message.contentsAsBytes()), 0, null, valueDecoder))
}
```
### Step 3 - validate that the message was handled correctly
```groovy
def order = orderRepository.getOrder('10000004')
assert order.status == 'confirmed'
assert order.value == 10.0
```
### Step 4 - Publish the pact file
If the test was successful, a pact file would have been produced with the message from step 1.

pact-jvm-provider-maven_2.12 from group au.com.dius (version 3.6.15)
Maven plugin to verify a provider
=================================
Maven plugin for verifying pacts against a provider.
The Maven plugin provides a `verify` goal which will verify all configured pacts against your provider.
## To Use It
### 1. Add the pact-jvm-provider-maven plugin to your `build` section of your pom file.
```xml
<build>
[...]
<plugins>
[...]
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
</plugin>
[...]
</plugins>
[...]
</build>
```
### 2. Define the pacts between your consumers and providers
You define all the providers and consumers within the configuration element of the maven plugin.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<consumers>
<!-- Again, you can define as many consumers for each provider as you need, but each must have a unique name -->
<consumer>
<name>consumer1</name>
<!-- currently supports a file path using pactFile or a URL using pactUrl -->
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### 3. Execute `mvn pact:verify`
You will have to have your provider running for this to pass.
## Verifying all pact files in a directory for a provider
You can specify a directory that contains pact files, and the Pact plugin will scan for all pact files that match that
provider and define a consumer for each pact file in the directory. Consumer name is read from contents of pact file.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<!-- You can define as many as you need, but each must have a unique name -->
<serviceProvider>
<name>provider1</name>
<!-- All the provider properties are optional, and have sensible defaults (shown below) -->
<protocol>http</protocol>
<host>localhost</host>
<port>8080</port>
<path>/</path>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying all pact files from multiple directories for a provider [3.5.18+]
If you want to specify multiple directories, you can use `pactFileDirectories`. The plugin will only fail the build if
no pact files are loaded after processing all the directories in the list.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.18</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectories>
<pactFileDirectory>path/to/pacts1</pactFileDirectory>
<pactFileDirectory>path/to/pacts2</pactFileDirectory>
</pactFileDirectories>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Enabling insecure SSL
For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting
`<insecure>true</insecure>` on the provider.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<insecure>true</insecure>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Specifying a custom trust store
For environments that are running their own certificate chains:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<pactFileDirectory>path/to/pacts</pactFileDirectory>
<trustStore>relative/path/to/trustStore.jks</trustStore>
<trustStorePassword>changeit</trustStorePassword>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
`trustStore` is either relative to the current working (build) directory. `trustStorePassword` defaults to `changeit`.
NOTE: The hostname will still be verified against the certificate.
## Modifying the requests before they are sent
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The Pact Maven plugin provides a request filter that can be
set to a Groovy script on the provider that will be called before the request is made. This script will receive the HttpRequest
bound to a variable named `request` prior to it being executed.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<requestFilter>
// This is a Groovy script that adds an Authorization header to each request
request.addHeader('Authorization', 'oauth-token eyJhbGciOiJSUzI1NiIsIm...')
</requestFilter>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
## Modifying the HTTP Client Used
The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`).
This can be changed by specifying a closure assigned to createClient on the provider that returns a CloseableHttpClient.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<createClient>
// This is a Groovy script that will enable the client to accept self-signed certificates
import org.apache.http.ssl.SSLContextBuilder
import org.apache.http.conn.ssl.NoopHostnameVerifier
import org.apache.http.impl.client.HttpClients
HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier())
.setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, { x509Certificates, s -> true })
.build())
.build()
</createClient>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
## Turning off URL decoding of the paths in the pact file
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
## Plugin Properties
The following plugin properties can be specified with `-Dproperty=value` on the command line or in the configuration section:
|Property|Description|
|--------|-----------|
|pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors|
|pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies|
|pact.filter.consumers|Comma separated list of consumer names to verify|
|pact.filter.description|Only verify interactions whose description match the provided regular expression|
|pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state|
|pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to `true` [version 3.5.18+]|
|pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to `true`|
|pact.verifier.disableUrlPathDecoding|Disables decoding of request paths|
|pact.pactbroker.httpclient.usePreemptiveAuthentication|Enables preemptive authentication with the pact broker when set to `true`|
|`pact.consumer.tags`|Overrides the tags used when publishing pacts [version 4.0.7+]|
Example in the configuration section:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<configuration>
<pact.showStacktrace>true</pact.showStacktrace>
</configuration>
</configuration>
</plugin>
```
## Provider States
For each provider you can specify a state change URL to use to switch the state of the provider. This URL will
receive the providerState description and parameters from the pact file before each interaction via a POST. The stateChangeUsesBody
controls if the state is passed in the request body or as query parameters.
These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/provider1-consumer1-pact.json</pactFile>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChangeForConsumer1</stateChangeUrl>
<stateChangeUsesBody>false</stateChangeUsesBody> <!-- defaults to true -->
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
If the `stateChangeUsesBody` is not specified, or is set to true, then the provider state description and parameters will be sent as
JSON in the body of the request. If it is set to false, they will passed as query parameters.
As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before
it is sent. Set `stateChangeRequestFilter` to a Groovy script on the provider that will be called before the request is made.
#### Teardown calls for state changes
You can enable teardown state change calls by setting the property `<stateChangeTeardown>true</stateChangeTeardown>` on the provider. This
will add an `action` parameter to the state change call. The setup call before the test will receive `action=setup`, and
then a teardown call will be made afterwards to the state change URL with `action=teardown`.
#### Returning values that can be injected (3.6.11+)
You can have values from the provider state callbacks be injected into most places (paths, query parameters, headers,
bodies, etc.). This works by using the V3 spec generators with provider state callbacks that return values. One example
of where this would be useful is API calls that require an ID which would be auto-generated by the database on the
provider side, so there is no way to know what the ID would be beforehand.
There are methods on the consumer DSLs that can provider an expression that contains variables (like '/api/user/${id}'
for the path). The provider state callback can then return a map for values, and the `id` attribute from the map will
be expanded in the expression. For URL callbacks, the values need to be returned as JSON in the response body.
## Verifying pact files from a pact broker
You can setup your build to validate against the pacts stored in a pact broker. The pact plugin will query
the pact broker for all consumers that have a pact with the provider based on its name. To use it, just configure the
`pactBrokerUrl` or `pactBroker` value for the provider with the base URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBrokerUrl>http://pact-broker:5000/</pactBrokerUrl>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an authenticated pact broker
If your pact broker requires authentication (basic authentication is only supported), you can configure the username
and password to use by configuring the `authentication` element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<authentication>
<username>test</username>
<password>test</password>
</authentication>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
Preemptive Authentication can be enabled by setting the `pact.pactbroker.httpclient.usePreemptiveAuthentication` Java
system property to `true`.
#### Using the Maven servers configuration [version 3.5.6+]
From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the
[Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker
configuration in your POM.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.6</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<serverId>test-pact-broker</serverId> <!-- This must match the server id in the maven settings -->
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
### Verifying pacts from an pact broker that match particular tags
If your pacts in your pact broker have been tagged, you can set the tags to fetch by configuring the `tags`
element of the `pactBroker` element of your provider.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>provider1</name>
<stateChangeUrl>http://localhost:8080/tasks/pactStateChange</stateChangeUrl>
<pactBroker>
<url>http://pactbroker:1234</url>
<tags>
<tag>TEST</tag>
<tag>DEV</tag>
</tags>
</pactBroker>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
This example will fetch and validate the pacts for the TEST and DEV tags.
## Filtering the interactions that are verified
You can filter the interactions that are run using three properties: `pact.filter.consumers`, `pact.filter.description` and `pact.filter.providerState`.
Adding `-Dpact.filter.consumers=consumer1,consumer2` to the command line or configuration section will only run the pact files for those
consumers (consumer1 and consumer2). Adding `-Dpact.filter.description=a request for payment.*` will only run those interactions
whose descriptions start with 'a request for payment'. `-Dpact.filter.providerState=.*payment` will match any interaction that
has a provider state that ends with payment, and `-Dpact.filter.providerState=` will match any interaction that does not have a
provider state.
## Not failing the build if no pact files are found [version 3.5.19+]
By default, if there are no pact files to verify, the plugin will raise an exception. This is to guard against false
positives where the build is passing but nothing has been verified due to mis-configuration.
To disable this behaviour, set the `failIfNoPactsFound` parameter to `false`.
# Verifying a message provider
The Maven plugin has been updated to allow invoking test methods that can return the message contents from a message
producer. To use it, set the way to invoke the verification to `ANNOTATED_METHOD`. This will allow the pact verification
task to scan for test methods that return the message contents.
Add something like the following to your maven pom file:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<!-- packagesToScan is optional, but leaving it out will result in the entire
test classpath being scanned. Set it to the packages where your annotated test method
can be found. -->
<packagesToScan>
<packageToScan>au.com.example.messageprovider.*</packageToScan>
</packagesToScan>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
</configuration>
</plugin>
```
Now when the pact verify task is run, will look for methods annotated with `@PactVerifyProvider` in the test classpath
that have a matching description to what is in the pact file.
```groovy
class ConfirmationKafkaMessageBuilderTest {
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setExchange('ASX')
order.setSecurityCode('CBA')
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
order.setGst(new BigDecimal('15.0'))
odrer.setFees(BigDecimal.TEN)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
It will then validate that the returned contents matches the contents for the message in the pact file.
## Changing the class path that is scanned
By default, the test classpath is scanned for annotated methods. You can override this by setting
the `classpathElements` property:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<serviceProviders>
<serviceProvider>
<name>messageProvider</name>
<verificationType>ANNOTATED_METHOD</verificationType>
<consumers>
<consumer>
<name>consumer1</name>
<pactFile>path/to/messageprovider-consumer1-pact.json</pactFile>
</consumer>
</consumers>
</serviceProvider>
</serviceProviders>
<classpathElements>
<classpathElement>
build/classes/test
</classpathElement>
</classpathElements>
</configuration>
</plugin>
```
# Publishing pact files to a pact broker
The pact maven plugin provides a `publish` mojo that can publish all pact files in a directory
to a pact broker. To use it, you need to add a publish configuration to the POM that defines the
directory where the pact files are and the URL to the pact broker.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<pactDirectory>path/to/pact/files</pactDirectory> <!-- Defaults to ${project.build.directory}/pacts -->
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<projectVersion>1.0.100</projectVersion> <!-- Defaults to ${project.version} -->
<trimSnapshot>true</trimSnapshot> <!-- Defaults to false -->
</configuration>
</plugin>
```
You can now execute `mvn pact:publish` to publish the pact files.
_NOTE:_ The pact broker requires a version for all published pacts. The `publish` task will use the version of the
project by default, but can be overwritten with the `projectVersion` property. Make sure you have set one otherwise the broker will reject the pact files.
_NOTE_: By default, the pact broker has issues parsing `SNAPSHOT` versions. You can configure the publisher to
automatically remove `-SNAPSHOT` from your version number by setting `trimSnapshot` to true. This setting does not modify non-snapshot versions.
You can set any tags that the pacts should be published with by setting the `tags` list property (version 3.5.12+). A common use of this
is setting the tag to the current source control branch. This supports using pact with feature branches.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.12</version>
<configuration>
<pactDirectory>path/to/pact/files</pactDirectory> <!-- Defaults to ${project.build.directory}/pacts -->
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<projectVersion>1.0.100</projectVersion> <!-- Defaults to ${project.version} -->
<tags>
<tag>feature/feature_name</tag>
</tags>
</configuration>
</plugin>
```
You can also specify the tags using the `pact.consumer.tags` Java system property [version 4.0.7+].
## Publishing to an authenticated pact broker
For an authenticated pact broker, you can pass in the credentials with the `pactBrokerUsername` and `pactBrokerPassword`
properties. Currently it only supports basic authentication.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerUsername>USERNAME</pactBrokerUsername>
<pactBrokerPassword>PASSWORD</pactBrokerPassword>
</configuration>
</plugin>
```
Or to use a bearer token:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.11</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerToken>TOKEN</pactBrokerToken> <!-- Replace TOKEN with the actual token -->
<pactBrokerAuthenticationScheme>Bearer</pactBrokerAuthenticationScheme>
</configuration>
</plugin>
```
#### Using the Maven servers configuration [version 3.5.6+]
From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the
[Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker
configuration in your POM.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.11</artifactId>
<version>3.5.19</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<pactBrokerServerId>test-pact-broker</pactBrokerServerId> <!-- This must match the server id in the maven settings -->
</configuration>
</plugin>
```
## Excluding pacts from being published [version 3.5.19+]
You can exclude some of the pact files from being published by providing a list of regular expressions that match
against the base names of the pact files.
For example:
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.19</version>
<configuration>
<pactBrokerUrl>http://pactbroker:1234</pactBrokerUrl>
<excludes>
<exclude>.*\\-\\d+$</exclude> <!-- exclude pact files where the name ends in a dash followed by a number -->
</excludes>
</configuration>
</plugin>
```
# Publishing verification results to a Pact Broker [version 3.5.4+]
For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the
broker against the URL for the pact. You will be able to then see the result on the Pact Broker home screen.
To turn on the verification publishing, set the system property `pact.verifier.publishResults` to `true` in the pact maven plugin, not surefire, configuration.
# Enabling other verification reports [version 3.5.20+]
By default the verification report is written to the console. You can also enable a JSON or Markdown report by setting
the `reports` configuration list.
```xml
<plugin>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-provider-maven_2.12</artifactId>
<version>3.5.20</version>
<configuration>
<reports>
<report>console</report>
<report>json</report>
<report>markdown</report>
</reports>
</configuration>
</plugin>
```
These reports will be written to `target/reports/pact`.

# Pact junit runner
## Overview
Library provides ability to play contract tests against a provider service in JUnit fashionable way.
Supports:
- Out-of-the-box convenient ways to load pacts
- Easy way to change assertion strategy
- **org.junit.BeforeClass**, **org.junit.AfterClass** and **org.junit.ClassRule** JUnit annotations, that will be run
once - before/after whole contract test suite.
- **org.junit.Before**, **org.junit.After** and **org.junit.Rule** JUnit annotations, that will be run before/after
each test of an interaction.
- **au.com.dius.pact.provider.junit.State** custom annotation - before each interaction that requires a state change,
all methods annotated by `@State` with appropriate the state listed will be invoked. These methods must either take
no parameters or a single Map parameter.
## Example of HTTP test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactFolder("pacts") // Point where to find pacts (See also section Pacts source in documentation)
public class ContractTest {
// NOTE: this is just an example of embedded service that listens to requests, you should start here real service
@ClassRule //Rule will be applied once: before/after whole contract test suite
public static final ClientDriverRule embeddedService = new ClientDriverRule(8332);
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Rest data
// Mock dependent service responses
// ...
embeddedService.addExpectation(
onRequestTo("/data"), giveEmptyResponse()
);
}
@State("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state
public void toDefaultState() {
// Prepare service before interaction that require "default" state
// ...
System.out.println("Now service in default state");
}
@State("with-data") // Method will be run before testing interactions that require "with-data" state
public void toStateWithData(Map data) {
// Prepare service before interaction that require "with-data" state. The provider state data will be passed
// in the data parameter
// ...
System.out.println("Now service in state using data " + data);
}
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new HttpTarget(8332); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
}
```
## Example of AMQP Message test
```java
@RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
@Provider("myAwesomeService") // Set up name of tested provider
@PactBroker(host="pactbroker", port = "80")
public class ConfirmationKafkaContractTest {
@TestTarget // Annotation denotes Target that will be used for tests
public final Target target = new AmqpTarget(); // Out-of-the-box implementation of Target (for more information take a look at Test Target section)
@BeforeClass //Method will be run once: before whole contract test suite
public static void setUpService() {
//Run DB, create schema
//Run service
//...
}
@Before //Method will be run before each test of interaction
public void before() {
// Message data preparation
// ...
}
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
## Provider state callback methods
For the provider states in the pact being verified, you can define methods to be invoked to setup the correct state
for each interaction. Just annotate a method with the `au.com.dius.pact.provider.junit.State` annotation and the
method will be invoked before the interaction is verified.
For example:
```java
@State("SomeProviderState") // Must match the state description in the pact file
public void someProviderState() {
// Do what you need to set the correct state
}
```
If there are parameters in the pact file, just add a Map parameter to the method to be able to access those parameters.
```java
@State("SomeProviderState")
public void someProviderState(Map<String, Object> providerStateParameters) {
// Do what you need to set the correct state
}
```
### Provider state teardown methods [3.5.22+]
If you need to tear down your provider state, you can annotate a method with the `@State` annotation with the action
set to `StateChangeAction.TEARDOWN` and it will be invoked after the interaction is verified.
```java
@State("SomeProviderState", action = StateChangeAction.TEARDOWN)
public void someProviderStateCleanup() {
// Do what you need to to teardown the state
}
```
#### Returning values that can be injected (3.6.11+)
You can have values from the provider state callbacks be injected into most places (paths, query parameters, headers,
bodies, etc.). This works by using the V3 spec generators with provider state callbacks that return values. One example
of where this would be useful is API calls that require an ID which would be auto-generated by the database on the
provider side, so there is no way to know what the ID would be beforehand.
There are methods on the consumer DSLs that can provider an expression that contains variables (like '/api/user/${id}'
for the path). The provider state callback can then return a map for values, and the `id` attribute from the map will
be expanded in the expression. For this to work, just make your provider state method return a Map of the values.
### Using multiple classes for the state change methods
If you have a large number of state change methods, you can split things up by moving them to other classes. There are
two ways you can do this:
#### Use interfaces
You can put the state change methods on interfaces and then have your test class implement those interfaces. See [StateAnnotationsOnInterfaceTest](src/test/java/au/com/dius/pact/provider/junit/StateAnnotationsOnInterfaceTest.java)
for an example.
#### Specify the additional classes on the test target
You can provide the additional classes to the test target with the `withStateHandler` or `setStateHandlers` methods. See
[BooksPactProviderTest](pact-jvm-provider-spring/src/test/java/au/com/dius/pact/provider/spring/BooksPactProviderTest.java) for an example.
## Pact source
The Pact runner will automatically collect pacts based on annotations on the test class. For this purpose there are 3
out-of-the-box options (files from a directory, files from a set of URLs or a pact broker) or you can easily add your
own Pact source.
If you need to load a single pact file from the file system, use the `PactUrl` with the URL set to the file path.
**Note:** You can only define one source of pacts per test class.
### Download pacts from a pact-broker
To use pacts from a Pact Broker, annotate the test class with `@PactBroker(host="host.of.pact.broker.com", port = "80")`.
From _version 3.2.2/2.4.3+_ you can also specify the protocol, which defaults to "http".
The pact broker will be queried for all pacts with the same name as the provider annotation.
For example, test all pacts for the "Activity Service" in the pact broker:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@PactBroker(host = "localhost", port = "80")
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
#### _Version 3.2.3/2.4.4+_ - Using Java System properties
The pact broker loader was updated to allow system properties to be used for the hostname, port or protocol. The port
was changed to a string to allow expressions to be set.
To use a system property or environment variable, you can place the property name in `${}` expression de-markers:
```java
@PactBroker(host="${pactbroker.hostname}", port = "80")
```
You can provide a default value by separating the property name with a colon (`:`):
```java
@PactBroker(host="${pactbroker.hostname:localhost}", port = "80")
```
#### _Version 3.5.3+_ - More Java System properties
The default values of the `@PactBroker` annotation now enable variable interpolation.
The following keys may be managed through the environment
* `pactbroker.host`
* `pactbroker.port`
* `pactbroker.protocol`
* `pactbroker.tags` (comma separated)
* `pactbroker.auth.username` (for basic auth)
* `pactbroker.auth.password` (for basic auth)
* `pactbroker.auth.token` (for bearer auth)
* `pactbroker.consumers` (comma separated list to filter pacts by consumer; if not provided, will fetch all pacts for the provider)
#### _Version 3.2.4/2.4.6+_ - Using tags with the pact broker
The pact broker allows different versions to be tagged. To load all the pacts:
```java
@PactBroker(host="pactbroker", port = "80", tags = {"latest", "dev", "prod"})
```
The default value for tags is `latest` which is not actually a tag but instead corresponds to the latest version ignoring the tags. If there are multiple consumers matching the name specified in the provider annotation then the latest pact for each of the consumers is loaded.
For any other value the latest pact tagged with the specified tag is loaded.
Specifying multiple tags is an OR operation. For example if you specify `tags = {"dev", "prod"}` then both the latest pact file tagged with `dev` and the latest pact file taggged with `prod` is loaded.
#### _Version 3.3.4/2.4.19+_ - Using basic auth with the with the pact broker
You can use basic authentication with the `@PactBroker` annotation by setting the `authentication` value to a `@PactBrokerAuth`
annotation. For example:
```java
@PactBroker(host = "${pactbroker.url:localhost}", port = "1234", tags = {"latest", "prod", "dev"},
authentication = @PactBrokerAuth(username = "test", password = "test"))
```
Bearer tokens are also supported. For example:
```java
@PactBroker(host = "${pactbroker.url:localhost}", port = "1234", tags = {"latest", "prod", "dev"},
authentication = @PactBrokerAuth(token = "test"))
```
The `token`, `username` and `password` values also take Java system property expressions.
Preemptive Authentication can be enabled by setting the `pact.pactbroker.httpclient.usePreemptiveAuthentication` Java
system property to `true`.
### Pact Url
To use pacts from urls annotate the test class with
```java
@PactUrl(urls = {"http://build.server/zoo_app-animal_service.json"} )
```
If you need to load a single pact file from the file system, you can use the `PactUrl` with the URL set to the file path.
### Pact folder
To use pacts from a resource folder of the project annotate test class with
```java
@PactFolder("subfolder/in/resource/directory")
```
### Custom pacts source
It's possible to use a custom Pact source. For this, implement interface `au.com.dius.pact.provider.junit.loader.PactLoader`
and annotate the test class with `@PactSource(MyOwnPactLoader.class)`. **Note:** class `MyOwnPactLoader` must have a default empty constructor or a constructor with one argument of class `Class` which at runtime will be the test class so you can get custom annotations of test class.
### Filtering the interactions that are verified [version 3.5.3+]
By default, the pact runner will verify all pacts for the given provider. You can filter the pacts and interactions by
the following methods.
#### Filtering by Consumer
You can run only those pacts for a particular consumer by adding a `@Consumer` annotation to the test class.
For example:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@Consumer("Activity Consumer")
@PactBroker(host = "localhost", port = "80")
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
#### Filtering by Provider State
You can filter the interactions that are executed by adding a `@PactFilter` annotation to your test class. The pact
filter annotation will then only verify interactions that have a matching provider state. You can provide multiple
states to match with.
For example:
```java
@RunWith(PactRunner.class)
@Provider("Activity Service")
@PactBroker(host = "localhost", port = "80")
@PactFilter('Activity 100 exists in the database')
public class PactJUnitTest {
@TestTarget
public final Target target = new HttpTarget(5050);
}
```
You can also use regular expressions with the filter [version 3.5.3+]. For example:
```java
@RunWith(PactRunner.class)
@PactFilter('Activity \\d+ exists in the database')
public class PactJUnitTest {
}
```
### Setting the test to not fail when no pacts are found [version 3.5.3+]
By default the pact runner will fail the verification test if no pact files are found to verify. To change the
failure into a warning, add a `@IgnoreNoPactsToVerify` annotation to your test class.
#### Ignoring IO errors loading pact files [version 3.5.24+]
You can also set the test to ignore any IO and parser exceptions when loading the pact files by setting the
`ignoreIoErrors` attribute on the annotation to `"true"` or setting the JVM system property `pact.verification.ignoreIoErrors`
to `true`.
** WARNING! Do not enable this on your CI server, as this could result in your build passing with no providers
having been verified due to a configuration error. **
## Test target
The field in test class of type `au.com.dius.pact.provider.junit.target.Target` annotated with `au.com.dius.pact.provider.junit.target.TestTarget`
will be used for actual Interaction execution and asserting of contract.
**Note:** there must be exactly 1 such field, otherwise an `InitializationException` will be thrown.
### HttpTarget
`au.com.dius.pact.provider.junit.target.HttpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as http request and assert response from service by matching rules from pact.
_Version 3.2.2/2.4.3+_ you can also specify the protocol, defaults to "http".
### AmqpTarget
`au.com.dius.pact.provider.junit.target.AmqpTarget` - out-of-the-box implementation of `au.com.dius.pact.provider.junit.target.Target`
that will play pacts as an AMQP message and assert response from service by matching rules from pact.
**Note for Maven users:** If you use Maven to run your tests, you will have to make sure that the Maven Surefire plugin is at least
version 2.22.1 uses an isolated classpath.
For example, configure it by adding the following to your POM:
```xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>
<configuration>
<useSystemClassLoader>false</useSystemClassLoader>
</configuration>
</plugin>
```
#### Modifying the requests before they are sent [Version 3.2.3/2.4.5+]
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The HttpTarget supports request filters by annotating methods
on the test class with `@TargetRequestFilter`. These methods must be public void methods that take a single HttpRequest
parameter.
For example:
```java
@TargetRequestFilter
public void exampleRequestFilter(HttpRequest request) {
request.addHeader("Authorization", "OAUTH hdsagasjhgdjashgdah...");
}
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
#### Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
### Custom Test Target
It's possible to use custom `Target`, for that interface `Target` should be implemented and this class can be used instead of `HttpTarget`.
# Verification Reports [versions 3.2.7/2.4.9+]
The default test behaviour is to display the verification being done to the console, and pass or fail the test via the normal
JUnit mechanism. From versions 3.2.7/2.4.9+, additional reports can be generated from the tests.
## Enabling additional reports via annotations on the test classes
A `@VerificationReports` annotation can be added to any pact test class which will control the verification output. The
annotation takes a list report types and an optional report directory (defaults to "target/pact/reports").
The currently supported report types are `console`, `markdown` and `json`.
For example:
```java
@VerificationReports({"console", "markdown"})
public class MyPactTest {
```
will enable the markdown report in addition to the normal console output. And,
```java
@VerificationReports(value = {"markdown"}, reportDir = "/myreports")
public class MyPactTest {
```
will disable the normal console output and write the markdown reports to "/myreports".
## Enabling additional reports via Java system properties or environment variables
The additional reports can also be enabled with Java System properties or environment variables. The following two
properties have been introduced: `pact.verification.reports` and `pact.verification.reportDir`.
`pact.verification.reports` is the comma separated list of report types to enable (e.g. `console,json,markdown`).
`pact.verification.reportDir` is the directory to write reports to (defaults to "target/pact/reports").
## Additional Reports
The following report types are available in addition to console output (`console`, which is enabled by default):
`markdown`, `json`.
You can also provide a fully qualified classname as report so custom reports are also supported.
This class must implement `au.com.dius.pact.provider.reporters.VerifierReporter` interface in order to be correct custom implementation of a report.
# Publishing verification results to a Pact Broker [version 3.5.4+]
For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the
broker against the URL for the pact. You will be able to see the result on the Pact Broker home screen. You need to
set the version of the provider that is verified using the `pact.provider.version` system property.
To enable publishing of results, set the property `pact.verifier.publishResults` to `true` [version 3.5.18+].

pact-jvm-provider-gradle
========================
Gradle plugin for verifying pacts against a provider.
The Gradle plugin creates a task `pactVerify` to your build which will verify all configured pacts against your provider.
## To Use It
### For Gradle versions prior to 2.1
#### 1.1. Add the pact-jvm-provider-gradle jar file to your build script class path:
```groovy
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'au.com.dius:pact-jvm-provider-gradle_2.10:3.2.11'
}
}
```
#### 1.2. Apply the pact plugin
```groovy
apply plugin: 'au.com.dius.pact'
```
### For Gradle versions 2.1+
```groovy
plugins {
id "au.com.dius.pact" version "3.2.11"
}
```
### 2. Define the pacts between your consumers and providers
```groovy
pact {
serviceProviders {
// You can define as many as you need, but each must have a unique name
provider1 {
// All the provider properties are optional, and have sensible defaults (shown below)
protocol = 'http'
host = 'localhost'
port = 8080
path = '/'
// Again, you can define as many consumers for each provider as you need, but each must have a unique name
hasPactWith('consumer1') {
// currently supports a file path using file() or a URL using url()
pactSource = file('path/to/provider1-consumer1-pact.json')
}
// Or if you have many pact files in a directory
hasPactsWith('manyConsumers') {
// Will define a consumer for each pact file in the directory.
// Consumer name is read from contents of pact file
pactFileLocation = file('path/to/pacts')
}
}
}
}
```
### 3. Execute `gradle pactVerify`
## Specifying the provider hostname at runtime
If you need to calculate the provider hostname at runtime, you can give a Closure as the provider `host`.
```groovy
pact {
serviceProviders {
provider1 {
host = { lookupHostName() }
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
_Since version 3.3.2+/2.4.17+_ you can also give a Closure as the provider `port`.
## Specifying the pact file or URL at runtime [versions 3.2.7/2.4.9+]
If you need to calculate the pact file or URL at runtime, you can give a Closure as the provider `pactFile`.
```groovy
pact {
serviceProviders {
provider1 {
host = 'localhost'
hasPactWith('consumer1') {
pactFile = { lookupPactFile() }
}
}
}
}
```
## Starting and shutting down your provider
If you need to start-up or shutdown your provider, define Gradle tasks for each action and set
`startProviderTask` and `terminateProviderTask` properties of each provider.
You could use the jetty tasks here if you provider is built as a WAR file.
```groovy
// This will be called before the provider task
task('startTheApp') {
doLast {
// start up your provider here
}
}
// This will be called after the provider task
task('killTheApp') {
doLast {
// kill your provider here
}
}
pact {
serviceProviders {
provider1 {
startProviderTask = startTheApp
terminateProviderTask = killTheApp
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
Following typical Gradle behaviour, you can set the provider task properties to the actual tasks, or to the task names
as a string (for the case when they haven't been defined yet).
## Preventing the chaining of provider verify task to `pactVerify` [version 3.4.1+]
Normally a gradle task named `pactVerify_${provider.name}` is created and added as a task dependency for `pactVerify`. You
can disable this dependency on a provider by setting `isDependencyForPactVerify` to `false` (defaults to `true`).
```groovy
pact {
serviceProviders {
provider1 {
isDependencyForPactVerify = false
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
To run this task, you would then have to explicitly name it as in ```gradle pactVerify_provider1```, a normal ```gradle pactVerify```
would skip it. This can be useful when you want to define two providers, one with `startProviderTask`/`terminateProviderTask`
and as second without, so you can manually start your provider (to debug it from your IDE, for example) but still want a `pactVerify`
to run normally from your CI build.
## Enabling insecure SSL [version 2.2.8+]
For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting
`insecure = true` on the provider.
```groovy
pact {
serviceProviders {
provider1 {
insecure = true // allow SSL with a self-signed cert
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
## Specifying a custom trust store [version 2.2.8+]
For environments that are running their own certificate chains:
```groovy
pact {
serviceProviders {
provider1 {
trustStore = new File('relative/path/to/trustStore.jks')
trustStorePassword = 'changeit'
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
`trustStore` is either relative to the current working (build) directory. `trustStorePassword` defaults to `changeit`.
NOTE: The hostname will still be verified against the certificate.
## Modifying the HTTP Client Used [version 2.2.4+]
The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`).
This can be changed by specifying a closure assigned to createClient on the provider that returns a CloseableHttpClient. For example:
```groovy
pact {
serviceProviders {
provider1 {
createClient = { provider ->
// This will enable the client to accept self-signed certificates
HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier())
.setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, { x509Certificates, s -> true })
.build())
.build()
}
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
## Modifying the requests before they are sent
**NOTE on breaking change: Version 2.1.8+ uses Apache HttpClient instead of HttpBuilder so the closure will receive a
HttpRequest object instead of a request Map.**
Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would
be authentication tokens, which have a small life span. The Pact Gradle plugin provides a request filter that can be
set to a closure on the provider that will be called before the request is made. This closure will receive the HttpRequest
prior to it being executed.
```groovy
pact {
serviceProviders {
provider1 {
requestFilter = { req ->
// Add an authorization header to each request
req.addHeader('Authorization', 'OAUTH eyJhbGciOiJSUzI1NiIsImN0eSI6ImFw...')
}
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
}
}
}
}
```
__*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying
the request, you are potentially modifying the contract from the consumer tests!
## Turning off URL decoding of the paths in the pact file [version 3.3.3+]
By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this
behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`.
__*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are
correctly encoded. The verifier will not be able to make a request with an invalid encoded path.
## Project Properties
The following project properties can be specified with `-Pproperty=value` on the command line:
|Property|Description|
|--------|-----------|
|pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors|
|pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies [version 3.3.6+]|
|pact.filter.consumers|Comma seperated list of consumer names to verify|
|pact.filter.description|Only verify interactions whose description match the provided regular expression|
|pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state|
|pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to 'true'|
|pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to 'true'|
|pact.verifier.disableUrlPathDecoding|Disables decoding of request paths|
|pact.pactbroker.httpclient.usePreemptiveAuthentication|Enables preemptive authentication with the pact broker when set to `true`|
## Provider States
For a description of what provider states are, see the pact documentations: http://docs.pact.io/documentation/provider_states.html
### Using a state change URL
For each provider you can specify a state change URL to use to switch the state of the provider. This URL will
receive the providerState description and all the parameters from the pact file before each interaction via a POST.
As for normal requests, a request filter (`stateChangeRequestFilter`) can also be set to manipulate the request before it is sent.
```groovy
pact {
serviceProviders {
provider1 {
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
stateChangeUrl = url('http://localhost:8001/tasks/pactStateChange')
stateChangeUsesBody = false // defaults to true
stateChangeRequestFilter = { req ->
// Add an authorization header to each request
req.addHeader('Authorization', 'OAUTH eyJhbGciOiJSUzI1NiIsImN0eSI6ImFw...')
}
}
// or
hasPactsWith('consumers') {
pactFileLocation = file('path/to/pacts')
stateChangeUrl = url('http://localhost:8001/tasks/pactStateChange')
stateChangeUsesBody = false // defaults to true
}
}
}
}
```
If the `stateChangeUsesBody` is not specified, or is set to true, then the provider state description and parameters
will be sent as JSON in the body of the request :
```json
{ "state" : "a provider state description", "params": { "a": "1", "b": "2" } }
```
If it is set to false, they will be passed as query parameters.
#### Teardown calls for state changes [version 3.2.5/2.4.7+]
You can enable teardown state change calls by setting the property `stateChangeTeardown = true` on the provider. This
will add an `action` parameter to the state change call. The setup call before the test will receive `action=setup`, and
then a teardown call will be made afterwards to the state change URL with `action=teardown`.
### Using a Closure [version 2.2.2+]
You can set a closure to be called before each verification with a defined provider state. The closure will be
called with the state description and parameters from the pact file.
```groovy
pact {
serviceProviders {
provider1 {
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
// Load a fixture file based on the provider state and then setup some database
// data. Does not require a state change request so returns false
stateChange = { providerState ->
// providerState is an instance of ProviderState
def fixture = loadFixtuerForProviderState(providerState)
setupDatabase(fixture)
}
}
}
}
}
```
#### Teardown calls for state changes [version 3.2.5/2.4.7+]
You can enable teardown state change calls by setting the property `stateChangeTeardown = true` on the provider. This
will add an `action` parameter to the state change closure call. The setup call before the test will receive `setup`,
as the second parameter, and then a teardown call will be made afterwards with `teardown` as the second parameter.
```groovy
pact {
serviceProviders {
provider1 {
hasPactWith('consumer1') {
pactFile = file('path/to/provider1-consumer1-pact.json')
// Load a fixture file based on the provider state and then setup some database
// data. Does not require a state change request so returns false
stateChange = { providerState, action ->
if (action == 'setup') {
def fixture = loadFixtuerForProviderState(providerState)
setupDatabase(fixture)
} else {
cleanupDatabase()
}
false
}
}
}
}
}
```
#### Returning values that can be injected (3.6.11+)
You can have values from the provider state callbacks be injected into most places (paths, query parameters, headers,
bodies, etc.). This works by using the V3 spec generators with provider state callbacks that return values. One example
of where this would be useful is API calls that require an ID which would be auto-generated by the database on the
provider side, so there is no way to know what the ID would be beforehand.
There are methods on the consumer DSLs that can provider an expression that contains variables (like '/api/user/${id}'
for the path). The provider state callback can then return a map for values, and the `id` attribute from the map will
be expanded in the expression. For URL callbacks, the values need to be returned as JSON in the response body.
## Filtering the interactions that are verified
You can filter the interactions that are run using three project properties: `pact.filter.consumers`, `pact.filter.description` and `pact.filter.providerState`.
Adding `-Ppact.filter.consumers=consumer1,consumer2` to the command line will only run the pact files for those
consumers (consumer1 and consumer2). Adding `-Ppact.filter.description=a request for payment.*` will only run those interactions
whose descriptions start with 'a request for payment'. `-Ppact.filter.providerState=.*payment` will match any interaction that
has a provider state that ends with payment, and `-Ppact.filter.providerState=` will match any interaction that does not have a
provider state.
## Verifying pact files from a pact broker [version 3.1.1+/2.3.1+]
You can setup your build to validate against the pacts stored in a pact broker. The pact gradle plugin will query
the pact broker for all consumers that have a pact with the provider based on its name.
For example:
```groovy
pact {
serviceProviders {
provider1 {
// You can get the latest pacts from the broker
hasPactsFromPactBroker('http://pact-broker:5000/')
// And/or you can get the latest pact with a specific tag
hasPactsFromPactBrokerWithTag('http://pact-broker:5000/',"tagname")
}
}
}
```
This will verify all pacts found in the pact broker where the provider name is 'provider1'. If you need to set any
values on the consumers from the pact broker, you can add a Closure to configure them.
```groovy
pact {
serviceProviders {
provider1 {
hasPactsFromPactBroker('http://pact-broker:5000/') { consumer ->
stateChange = { providerState -> /* state change code here */ true }
}
}
}
}
```
**NOTE: Currently the pacts are fetched from the broker during the configuration phase of the build. This means that
if the broker is not available, you will not be able to run any Gradle tasks.** This should be fixed in a forth coming
release.
In the mean time, to only load the pacts when running the validate task, you can do something like:
```groovy
pact {
serviceProviders {
provider1 {
// Only load the pacts from the broker if the start tasks from the command line include pactVerify
if ('pactVerify' in gradle.startParameter.taskNames) {
hasPactsFromPactBroker('http://pact-broker:5000/') { consumer ->
stateChange = { providerState -> /* state change code here */ true }
}
}
}
}
}
```
### Using an authenticated Pact Broker
You can add the authentication details for the Pact Broker like so:
```groovy
pact {
serviceProviders {
provider1 {
hasPactsFromPactBroker('http://pact-broker:5000/', authentication: ['Basic', pactBrokerUser, pactBrokerPassword])
}
}
}
```
`pactBrokerUser` and `pactBrokerPassword` can be defined in the gradle properties.
Or with a bearer token:
```groovy
pact {
serviceProviders {
provider1 {
hasPactsFromPactBroker('http://pact-broker:5000/', authentication: ['Bearer', pactBrokerToken])
}
}
}
```
Preemptive Authentication can be enabled by setting the `pact.pactbroker.httpclient.usePreemptiveAuthentication` Java
system property to `true`.
## Verifying pact files from a S3 bucket [version 3.3.2+/2.4.17+]
Pact files stored in an S3 bucket can be verified by using an S3 URL to the pact file. I.e.,
```groovy
pact {
serviceProviders {
provider1 {
hasPactWith('consumer1') {
pactFile = 's3://bucketname/path/to/provider1-consumer1-pact.json'
}
}
}
}
```
**NOTE:** you can't use the `url` function with S3 URLs, as the URL and URI classes from the Java SDK
don't support URLs with the s3 scheme.
# Publishing pact files to a pact broker [version 2.2.7+]
The pact gradle plugin provides a `pactPublish` task that can publish all pact files in a directory
to a pact broker. To use it, you need to add a publish configuration to the pact configuration that defines the
directory where the pact files are and the URL to the pact broker.
For example:
```groovy
pact {
publish {
pactDirectory = '/pact/dir' // defaults to $buildDir/pacts
pactBrokerUrl = 'http://pactbroker:1234'
}
}
```
You can set any tags that the pacts should be published with by setting the `tags` property. A common use of this
is setting the tag to the current source control branch. This supports using pact with feature branches.
```groovy
pact {
publish {
pactDirectory = '/pact/dir' // defaults to $buildDir/pacts
pactBrokerUrl = 'http://pactbroker:1234'
tags = [project.pactBrokerTag]
}
}
```
_NOTE:_ The pact broker requires a version for all published pacts. The `pactPublish` task will use the version of the
gradle project by default. Make sure you have set one otherwise the broker will reject the pact files.
_Version 3.2.2/2.4.3+_ you can override the version in the publish block.
## Publishing to an authenticated pact broker
To publish to a broker protected by basic auth, include the username/password in the `pactBrokerUrl`.
For example:
```groovy
pact {
publish {
pactBrokerUrl = 'https://username:[email protected]'
}
}
```
### [version 3.3.9+]
You can add the username and password as properties since version 3.3.9+
```groovy
pact {
publish {
pactBrokerUrl = 'https://mypactbroker.com'
pactBrokerUsername = 'username'
pactBrokerPassword = 'password'
}
}
```
or with a bearer token
```groovy
pact {
publish {
pactBrokerUrl = 'https://mypactbroker.com'
pactBrokerToken = 'token'
}
}
```
## Excluding pacts from being published [version 3.5.19+]
You can exclude some of the pact files from being published by providing a list of regular expressions that match
against the base names of the pact files.
For example:
```groovy
pact {
publish {
pactBrokerUrl = 'https://mypactbroker.com'
excludes = [ '.*\\-\\d+$' ] // exclude all pact files that end with a dash followed by a number in the name
}
}
```
# Verifying a message provider [version 2.2.12+]
The Gradle plugin has been updated to allow invoking test methods that can return the message contents from a message
producer. To use it, set the way to invoke the verification to `ANNOTATED_METHOD`. This will allow the pact verification
task to scan for test methods that return the message contents.
Add something like the following to your gradle build file:
```groovy
pact {
serviceProviders {
messageProvider {
verificationType = 'ANNOTATED_METHOD'
packagesToScan = ['au.com.example.messageprovider.*'] // This is optional, but leaving it out will result in the entire
// test classpath being scanned
hasPactWith('messageConsumer') {
pactFile = url('url/to/messagepact.json')
}
}
}
}
```
Now when the `pactVerify` task is run, will look for methods annotated with `@PactVerifyProvider` in the test classpath
that have a matching description to what is in the pact file.
```groovy
class ConfirmationKafkaMessageBuilderTest {
@PactVerifyProvider('an order confirmation message')
String verifyMessageForOrder() {
Order order = new Order()
order.setId(10000004)
order.setExchange('ASX')
order.setSecurityCode('CBA')
order.setPrice(BigDecimal.TEN)
order.setUnits(15)
order.setGst(new BigDecimal('15.0'))
order.setFees(BigDecimal.TEN)
def message = new ConfirmationKafkaMessageBuilder()
.withOrder(order)
.build()
JsonOutput.toJson(message)
}
}
```
It will then validate that the returned contents matches the contents for the message in the pact file.
## Publishing to the Gradle Community Portal
To publish the plugin to the community portal:
$ ./gradlew :pact-jvm-provider-gradle_2.11:publishPlugins
# Verification Reports [versions 3.2.7/2.4.9+]
The default behaviour is to display the verification being done to the console, and pass or fail the build via the normal
Gradle mechanism. From versions 3.2.7/2.4.9+, additional reports can be generated from the verification.
## Enabling additional reports
The verification reports can be controlled by adding a reports section to the pact configuration in the gradle build file.
For example:
```groovy
pact {
reports {
defaultReports() // adds the standard console output
markdown // report in markdown format
json // report in json format
}
}
```
Any report files will be written to "build/reports/pact".
## Additional Reports
The following report types are available in addition to console output (which is enabled by default):
`markdown`, `json`.
# Publishing verification results to a Pact Broker [version 3.5.4+]
For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the
broker against the URL for the pact. You will be able to see the result on the Pact Broker home screen.
To turn on the verification publishing, set the project property `pact.verifier.publishResults` to `true` [version 3.5.18+].
