# 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.
#### 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 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"
}
}
}
}
}
```

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-lein_2.10 from group au.com.dius (version 2.4.20)
# 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 "3.0.3" :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.
## 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.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, 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

:host #(calculate-host-name %)
:has-pact-with {
:consumer1 {
:pact-file "path/to/provider1-consumer1-pact.json"
}
}
}
}
}

pact-jvm-consumer_2.10 from group au.com.dius (version 2.4.20)
Pact consumer
=============
Pact Consumer is used by projects that are consumers of an API.
Most projects will want to use pact-consumer via one of the test framework specific projects. If your favourite
framework is not implemented, this module should give you all the hooks you need.
Provides a DSL for use with Java to build consumer pacts.
## Dependency
The library is available on maven central using:
* group-id = `au.com.dius`
* artifact-id = `pact-jvm-consumer_2.11`
## DSL Usage
Example in a JUnit test:
```java
import au.com.dius.pact.model.MockProviderConfig;
import au.com.dius.pact.model.PactFragment;
import org.junit.Test;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import static org.junit.Assert.assertEquals;
public class PactTest {
@Test
public void testPact() {
PactFragment pactFragment = ConsumerPactBuilder
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.uponReceiving("a request to say Hello")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.toFragment();
MockProviderConfig config = MockProviderConfig.createDefault();
VerificationResult result = pactFragment.runConsumer(config, new TestRun() {
@Override
public void run(MockProviderConfig config) {
Map expectedResponse = new HashMap();
expectedResponse.put("hello", "harry");
try {
assertEquals(new ProviderClient(config.url()).hello("{\"name\": \"harry\"}"),
expectedResponse);
} catch (IOException e) {}
}
});
if (result instanceof PactError) {
throw new RuntimeException(((PactError)result).error());
}
assertEquals(ConsumerPactTest.PACT_VERIFIED, result);
}
}
```
The DSL has the following pattern:
```java
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.given("a certain state on the provider")
.uponReceiving("a request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.uponReceiving("another request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.
.
.
.toFragment()
```
You can define as many interactions as required. Each interaction starts with `uponReceiving` followed by `willRespondWith`.
The test state setup with `given` is a mechanism to describe what the state of the provider should be in before the provider
is verified. It is only recorded in the consumer tests and used by the provider verification tasks.
### Building JSON bodies with PactDslJsonBody DSL
The body method of the ConsumerPactBuilder can accept a PactDslJsonBody, which can construct a JSON body as well as
define regex and type matchers.
For example:
```java
PactDslJsonBody body = new PactDslJsonBody()
.stringType("name")
.booleanType("happy")
.hexValue("hexCode")
.id()
.ipAddress("localAddress")
.numberValue("age", 100)
.timestamp();
```
#### DSL Matching methods
The following matching methods are provided with the DSL. In most cases, they take an optional value parameter which
will be used to generate example values (i.e. when returning a mock response). If no example value is given, a random
one will be generated.
| method | description |
|--------|-------------|
| string, stringValue | Match a string value (using string equality) |
| number, numberValue | Match a number value (using Number.equals)\* |
| booleanValue | Match a boolean value (using equality) |
| stringType | Will match all Strings |
| numberType | Will match all numbers\* |
| integerType | Will match all numbers that are integers (both ints and longs)\* |
| decimalType | Will match all real numbers (floating point and decimal)\* |
| booleanType | Will match all boolean values (true and false) |
| stringMatcher | Will match strings using the provided regular expression |
| timestamp | Will match string containing timestamps. If a timestamp format is not given, will match an ISO timestamp format |
| date | Will match string containing dates. If a date format is not given, will match an ISO date format |
| time | Will match string containing times. If a time format is not given, will match an ISO time format |
| ipAddress | Will match string containing IP4 formatted address. |
| id | Will match all numbers by type |
| hexValue | Will match all hexadecimal encoded strings |
| uuid | Will match strings containing UUIDs |
_\* Note:_ JSON only supports double precision floating point values. Depending on the language implementation, they
may parsed as integer, floating point or decimal numbers.
#### 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 `arrayLike`,
`minArrayLike` and `maxArrayLike` functions.
| function | description |
|----------|-------------|
| `eachLike` | Ensure that each item in the list matches the provided example |
| `maxArrayLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `minArrayLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
DslPart body = new PactDslJsonBody()
.minArrayLike("users")
.id()
.stringType("name")
.closeObject()
.closeArray();
```
This will ensure that the users list is never empty and that each user has an identifier that is a number and a name that is a string.
#### Matching JSON values at the root (Version 3.2.2/2.4.3+)
For cases where you are expecting basic JSON values (strings, numbers, booleans and null) at the root level of the body
and need to use matchers, you can use the `PactDslJsonRootValue` class. It has all the DSL matching methods for basic
values that you can use.
For example:
```java
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.uponReceiving("a request for a basic JSON value")
.path("/hello")
.willRespondWith()
.status(200)
.body(PactDslJsonRootValue.integerType())
```
#### Root level arrays that match all items (version 2.2.11+)
If the root of the body is an array, you can create PactDslJsonArray classes with the following methods:
| function | description |
|----------|-------------|
| `arrayEachLike` | Ensure that each item in the list matches the provided example |
| `arrayMinLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `arrayMaxLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
PactDslJsonArray.arrayEachLike()
.date("clearedDate", "mm/dd/yyyy", date)
.stringType("status", "STATUS")
.decimalType("amount", 100.0)
.closeObject()
```
This will then match a body like:
```json
[ {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
} ]
```
#### Matching arrays of arrays (version 3.2.12/2.4.14+)
For the case where you have arrays of arrays (GeoJSON is an example), the following methods have been provided:
| function | description |
|----------|-------------|
| `eachArrayLike` | Ensure that each item in the array is an array that matches the provided example |
| `eachArrayWithMaxLike` | Ensure that each item in the array is an array that matches the provided example and the array is no bigger than the provided max |
| `eachArrayWithMinLike` | Ensure that each item in the array is an array that matches the provided example and the array is no smaller than the provided min |
For example (with GeoJSON structure):
```java
new PactDslJsonBody()
.stringType("type","FeatureCollection")
.eachLike("features")
.stringType("type","Feature")
.object("geometry")
.stringType("type","Point")
.eachArrayLike("coordinates") // coordinates is an array of arrays
.decimalType(-7.55717)
.decimalType(49.766896)
.closeArray()
.closeArray()
.closeObject()
.object("properties")
.stringType("prop0","value0")
.closeObject()
.closeObject()
.closeArray()
```
This generated the following JSON:
```json
{
"features": [
{
"geometry": {
"coordinates": [[-7.55717, 49.766896]],
"type": "Point"
},
"type": "Feature",
"properties": { "prop0": "value0" }
}
],
"type": "FeatureCollection"
}
```
and will be able to match all coordinates regardless of the number of coordinates.
#### 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 `eachKeyLike` method, which takes an
example key as a parameter.
For example:
```java
DslPart body = new PactDslJsonBody()
.object("one")
.eachKeyLike("001", PactDslJsonRootValue.id(12345L)) // key like an id mapped to a matcher
.closeObject()
.object("two")
.eachKeyLike("001-A") // key like an id where the value is matched by the following example
.stringType("description", "Some Description")
.closeObject()
.closeObject()
.object("three")
.eachKeyMappedToAnArrayLike("001") // key like an id mapped to an array where each item is matched by the following example
.id("someId", 23456L)
.closeObject()
.closeArray()
.closeObject();
```
For an example, have a look at [WildcardKeysTest](src/test/java/au/com/dius/pact/consumer/WildcardKeysTest.java).
**NOTE:** The `eachKeyLike` 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 `eachKeyLike` condition
applied to a map will result in only one being applied when the pact is verified (probably the last).
### Matching on paths (version 2.1.5+)
You can use regular expressions to match incoming requests. The DSL has a `matchPath` method for this. You can provide
a real path as a second value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.matchPath("/transaction/[0-9]+") // or .matchPath("/transaction/[0-9]+", "/transaction/1234567890")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```
### Matching on headers (version 2.2.2+)
You can use regular expressions to match request and response headers. The DSL has a `matchHeader` method for this. You can provide
an example header value to use when generating requests and responses, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchHeader("testreqheader", "test.*value")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.matchHeader("Location", ".*/hello/[0-9]+", "/hello/1234")
```
### Matching on query parameters (version 3.3.7+)
You can use regular expressions to match request query parameters. The DSL has a `matchQuery` method for this. You can provide
an example value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchQuery("a", "\\d+", "100")
.matchQuery("b", "[A-Z]", "X")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```

.consumer("Some Consumer")
.hasPactWith("Some Provider")
.given("a certain state on the provider")
.uponReceiving("a request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.uponReceiving("another request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.
.
.
.toPact()
```
You can define as many interactions as required. Each interaction starts with `uponReceiving` followed by `willRespondWith`.
The test state setup with `given` is a mechanism to describe what the state of the provider should be in before the provider
is verified. It is only recorded in the consumer tests and used by the provider verification tasks.
### Building JSON bodies with PactDslJsonBody DSL
The body method of the ConsumerPactBuilder can accept a PactDslJsonBody, which can construct a JSON body as well as
define regex and type matchers.
For example:
```java
PactDslJsonBody body = new PactDslJsonBody()
.stringType("name")
.booleanType("happy")
.hexValue("hexCode")
.id()
.ipAddress("localAddress")
.numberValue("age", 100)
.timestamp();
```
#### DSL Matching methods
The following matching methods are provided with the DSL. In most cases, they take an optional value parameter which
will be used to generate example values (i.e. when returning a mock response). If no example value is given, a random
one will be generated.
| method | description |
|--------|-------------|
| string, stringValue | Match a string value (using string equality) |
| number, numberValue | Match a number value (using Number.equals)\* |
| booleanValue | Match a boolean value (using equality) |
| stringType | Will match all Strings |
| numberType | Will match all numbers\* |
| integerType | Will match all numbers that are integers (both ints and longs)\* |
| decimalType | Will match all real numbers (floating point and decimal)\* |
| booleanType | Will match all boolean values (true and false) |
| stringMatcher | Will match strings using the provided regular expression |
| timestamp | Will match string containing timestamps. If a timestamp format is not given, will match an ISO timestamp format |
| date | Will match string containing dates. If a date format is not given, will match an ISO date format |
| time | Will match string containing times. If a time format is not given, will match an ISO time format |
| ipAddress | Will match string containing IP4 formatted address. |
| id | Will match all numbers by type |
| hexValue | Will match all hexadecimal encoded strings |
| uuid | Will match strings containing UUIDs |
| includesStr | Will match strings containing the provided string |
| equalsTo | Will match using equals |
| matchUrl | Defines a matcher for URLs, given the base URL path and a sequence of path fragments. The path fragments could be
strings or regular expression matchers |
_\* Note:_ JSON only supports double precision floating point values. Depending on the language implementation, they
may parsed as integer, floating point or decimal numbers.
#### 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 `arrayLike`,
`minArrayLike` and `maxArrayLike` functions.
| function | description |
|----------|-------------|
| `eachLike` | Ensure that each item in the list matches the provided example |
| `maxArrayLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `minArrayLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
DslPart body = new PactDslJsonBody()
.minArrayLike("users")
.id()
.stringType("name")
.closeObject()
.closeArray();
```
This will ensure that the users list is never empty and that each user has an identifier that is a number and a name that is a string.
#### Matching JSON values at the root (Version 3.2.2/2.4.3+)
For cases where you are expecting basic JSON values (strings, numbers, booleans and null) at the root level of the body
and need to use matchers, you can use the `PactDslJsonRootValue` class. It has all the DSL matching methods for basic
values that you can use.
For example:
```java
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.uponReceiving("a request for a basic JSON value")
.path("/hello")
.willRespondWith()
.status(200)
.body(PactDslJsonRootValue.integerType())
```
#### Root level arrays that match all items (version 2.2.11+)
If the root of the body is an array, you can create PactDslJsonArray classes with the following methods:
| function | description |
|----------|-------------|
| `arrayEachLike` | Ensure that each item in the list matches the provided example |
| `arrayMinLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `arrayMaxLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
PactDslJsonArray.arrayEachLike()
.date("clearedDate", "mm/dd/yyyy", date)
.stringType("status", "STATUS")
.decimalType("amount", 100.0)
.closeObject()
```
This will then match a body like:
```json
[ {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
} ]
```
#### Matching arrays of arrays (version 3.2.12/2.4.14+)
For the case where you have arrays of arrays (GeoJSON is an example), the following methods have been provided:
| function | description |
|----------|-------------|
| `eachArrayLike` | Ensure that each item in the array is an array that matches the provided example |
| `eachArrayWithMaxLike` | Ensure that each item in the array is an array that matches the provided example and the array is no bigger than the provided max |
| `eachArrayWithMinLike` | Ensure that each item in the array is an array that matches the provided example and the array is no smaller than the provided min |
For example (with GeoJSON structure):
```java
new PactDslJsonBody()
.stringType("type","FeatureCollection")
.eachLike("features")
.stringType("type","Feature")
.object("geometry")
.stringType("type","Point")
.eachArrayLike("coordinates") // coordinates is an array of arrays
.decimalType(-7.55717)
.decimalType(49.766896)
.closeArray()
.closeArray()
.closeObject()
.object("properties")
.stringType("prop0","value0")
.closeObject()
.closeObject()
.closeArray()
```
This generated the following JSON:
```json
{
"features": [
{
"geometry": {
"coordinates": [[-7.55717, 49.766896]],
"type": "Point"
},
"type": "Feature",
"properties": { "prop0": "value0" }
}
],
"type": "FeatureCollection"
}
```
and will be able to match all coordinates regardless of the number of coordinates.
#### 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/313). In this case you can use the `eachKeyLike` method, which takes an
example key as a parameter.
For example:
```java
DslPart body = new PactDslJsonBody()
.object("one")
.eachKeyLike("001", PactDslJsonRootValue.id(12345L)) // key like an id mapped to a matcher
.closeObject()
.object("two")
.eachKeyLike("001-A") // key like an id where the value is matched by the following example
.stringType("description", "Some Description")
.closeObject()
.closeObject()
.object("three")
.eachKeyMappedToAnArrayLike("001") // key like an id mapped to an array where each item is matched by the following example
.id("someId", 23456L)
.closeObject()
.closeArray()
.closeObject();
```
For an example, have a look at [WildcardKeysTest](../pact-jvm-consumer-junit/src/test/java/au/com/dius/pact/consumer/WildcardKeysTest.java).
**NOTE:** The `eachKeyLike` 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 `eachKeyLike` condition
applied to a map will result in only one being applied when the pact is verified (probably the last).
**Further Note: From version 3.5.22 onwards pacts with wildcards applied to map keys will require the Java system property
"pact.matching.wildcard" set to value "true" when the pact file is verified.**
### Matching on paths (version 2.1.5+)
You can use regular expressions to match incoming requests. The DSL has a `matchPath` method for this. You can provide
a real path as a second value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.matchPath("/transaction/[0-9]+") // or .matchPath("/transaction/[0-9]+", "/transaction/1234567890")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```
### Matching on headers (version 2.2.2+)
You can use regular expressions to match request and response headers. The DSL has a `matchHeader` method for this. You can provide
an example header value to use when generating requests and responses, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchHeader("testreqheader", "test.*value")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.matchHeader("Location", ".*/hello/[0-9]+", "/hello/1234")
```
### Matching on query parameters (version 3.3.7+)
You can use regular expressions to match request query parameters. The DSL has a `matchQuery` method for this. You can provide
an example value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchQuery("a", "\\d+", "100")
.matchQuery("b", "[A-Z]", "X")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```
# Forcing pact files to be overwritten (3.6.5+)
By default, when the pact file is written, it will be merged with any existing pact file. To force the file to be
overwritten, set the Java system property `pact.writer.overwrite` to `true`.
# Having values injected from provider state callbacks (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.
The following DSL methods allow you to set an expression that will be parsed with the values returned from the provider states:
For JSON bodies, use `valueFromProviderState`.<br/>
For headers, use `headerFromProviderState`.<br/>
For query parameters, use `queryParameterFromProviderState`.<br/>
For paths, use `pathFromProviderState`.
For example, assume that an API call is made to get the details of a user by ID. A provider state can be defined that
specifies that the user must be exist, but the ID will be created when the user is created. So we can then define an
expression for the path where the ID will be replaced with the value returned from the provider state callback.
```java
.pathFromProviderState("/api/users/${id}", "/api/users/100")
```
You can also just use the key instead of an expression:
```java
.valueFromProviderState('userId', 'userId', 100) // will look value using userId as the key
```

pact-jvm-consumer from group au.com.dius (version 4.0.10)
Pact consumer
=============
Pact Consumer is used by projects that are consumers of an API.
Most projects will want to use pact-consumer via one of the test framework specific projects. If your favourite
framework is not implemented, this module should give you all the hooks you need.
Provides a DSL for use with Java to build consumer pacts.
## Dependency
The library is available on maven central using:
* group-id = `au.com.dius`
* artifact-id = `pact-jvm-consumer`
## DSL Usage
Example in a JUnit test:
```java
import au.com.dius.pact.model.MockProviderConfig;
import au.com.dius.pact.model.RequestResponsePact;
import org.apache.http.entity.ContentType;
import org.jetbrains.annotations.NotNull;
import org.junit.Test;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import static au.com.dius.pact.consumer.ConsumerPactRunnerKt.runConsumerTest;
import static org.junit.Assert.assertEquals;
public class PactTest {
@Test
public void testPact() {
RequestResponsePact pact = ConsumerPactBuilder
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.uponReceiving("a request to say Hello")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.toPact();
MockProviderConfig config = MockProviderConfig.createDefault();
PactVerificationResult result = runConsumerTest(pact, config, new PactTestRun() {
@Override
public void run(@NotNull MockServer mockServer) throws IOException {
Map expectedResponse = new HashMap();
expectedResponse.put("hello", "harry");
assertEquals(expectedResponse, new ConsumerClient(mockServer.getUrl()).post("/hello",
"{\"name\": \"harry\"}", ContentType.APPLICATION_JSON));
}
});
if (result instanceof PactVerificationResult.Error) {
throw new RuntimeException(((PactVerificationResult.Error)result).getError());
}
assertEquals(PactVerificationResult.Ok.INSTANCE, result);
}
}
```
The DSL has the following pattern:
```java
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.given("a certain state on the provider")
.uponReceiving("a request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.uponReceiving("another request for something")
.path("/hello")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.
.
.
.toPact()
```
You can define as many interactions as required. Each interaction starts with `uponReceiving` followed by `willRespondWith`.
The test state setup with `given` is a mechanism to describe what the state of the provider should be in before the provider
is verified. It is only recorded in the consumer tests and used by the provider verification tasks.
### Building JSON bodies with PactDslJsonBody DSL
The body method of the ConsumerPactBuilder can accept a PactDslJsonBody, which can construct a JSON body as well as
define regex and type matchers.
For example:
```java
PactDslJsonBody body = new PactDslJsonBody()
.stringType("name")
.booleanType("happy")
.hexValue("hexCode")
.id()
.ipAddress("localAddress")
.numberValue("age", 100)
.timestamp();
```
#### DSL Matching methods
The following matching methods are provided with the DSL. In most cases, they take an optional value parameter which
will be used to generate example values (i.e. when returning a mock response). If no example value is given, a random
one will be generated.
| method | description |
|--------|-------------|
| string, stringValue | Match a string value (using string equality) |
| number, numberValue | Match a number value (using Number.equals)\* |
| booleanValue | Match a boolean value (using equality) |
| stringType | Will match all Strings |
| numberType | Will match all numbers\* |
| integerType | Will match all numbers that are integers (both ints and longs)\* |
| decimalType | Will match all real numbers (floating point and decimal)\* |
| booleanType | Will match all boolean values (true and false) |
| stringMatcher | Will match strings using the provided regular expression |
| timestamp | Will match string containing timestamps. If a timestamp format is not given, will match an ISO timestamp format |
| date | Will match string containing dates. If a date format is not given, will match an ISO date format |
| time | Will match string containing times. If a time format is not given, will match an ISO time format |
| ipAddress | Will match string containing IP4 formatted address. |
| id | Will match all numbers by type |
| hexValue | Will match all hexadecimal encoded strings |
| uuid | Will match strings containing UUIDs |
| includesStr | Will match strings containing the provided string |
| equalsTo | Will match using equals |
| matchUrl | Defines a matcher for URLs, given the base URL path and a sequence of path fragments. The path fragments could be
strings or regular expression matchers |
_\* Note:_ JSON only supports double precision floating point values. Depending on the language implementation, they
may parsed as integer, floating point or decimal numbers.
#### 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 `arrayLike`,
`minArrayLike` and `maxArrayLike` functions.
| function | description |
|----------|-------------|
| `eachLike` | Ensure that each item in the list matches the provided example |
| `maxArrayLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `minArrayLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
DslPart body = new PactDslJsonBody()
.minArrayLike("users")
.id()
.stringType("name")
.closeObject()
.closeArray();
```
This will ensure that the users list is never empty and that each user has an identifier that is a number and a name that is a string.
#### Matching JSON values at the root
For cases where you are expecting basic JSON values (strings, numbers, booleans and null) at the root level of the body
and need to use matchers, you can use the `PactDslJsonRootValue` class. It has all the DSL matching methods for basic
values that you can use.
For example:
```java
.consumer("Some Consumer")
.hasPactWith("Some Provider")
.uponReceiving("a request for a basic JSON value")
.path("/hello")
.willRespondWith()
.status(200)
.body(PactDslJsonRootValue.integerType())
```
#### Root level arrays that match all items
If the root of the body is an array, you can create PactDslJsonArray classes with the following methods:
| function | description |
|----------|-------------|
| `arrayEachLike` | Ensure that each item in the list matches the provided example |
| `arrayMinLike` | Ensure that each item in the list matches the provided example and the list is no bigger than the provided max |
| `arrayMaxLike` | Ensure that each item in the list matches the provided example and the list is no smaller than the provided min |
For example:
```java
PactDslJsonArray.arrayEachLike()
.date("clearedDate", "mm/dd/yyyy", date)
.stringType("status", "STATUS")
.decimalType("amount", 100.0)
.closeObject()
```
This will then match a body like:
```json
[ {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
}, {
"clearedDate" : "07/22/2015",
"status" : "C",
"amount" : 15.0
} ]
```
#### Matching arrays of arrays
For the case where you have arrays of arrays (GeoJSON is an example), the following methods have been provided:
| function | description |
|----------|-------------|
| `eachArrayLike` | Ensure that each item in the array is an array that matches the provided example |
| `eachArrayWithMaxLike` | Ensure that each item in the array is an array that matches the provided example and the array is no bigger than the provided max |
| `eachArrayWithMinLike` | Ensure that each item in the array is an array that matches the provided example and the array is no smaller than the provided min |
For example (with GeoJSON structure):
```java
new PactDslJsonBody()
.stringType("type","FeatureCollection")
.eachLike("features")
.stringType("type","Feature")
.object("geometry")
.stringType("type","Point")
.eachArrayLike("coordinates") // coordinates is an array of arrays
.decimalType(-7.55717)
.decimalType(49.766896)
.closeArray()
.closeArray()
.closeObject()
.object("properties")
.stringType("prop0","value0")
.closeObject()
.closeObject()
.closeArray()
```
This generated the following JSON:
```json
{
"features": [
{
"geometry": {
"coordinates": [[-7.55717, 49.766896]],
"type": "Point"
},
"type": "Feature",
"properties": { "prop0": "value0" }
}
],
"type": "FeatureCollection"
}
```
and will be able to match all coordinates regardless of the number of coordinates.
#### Matching any key in a map
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/313). In this case you can use the `eachKeyLike` method, which takes an
example key as a parameter.
For example:
```java
DslPart body = new PactDslJsonBody()
.object("one")
.eachKeyLike("001", PactDslJsonRootValue.id(12345L)) // key like an id mapped to a matcher
.closeObject()
.object("two")
.eachKeyLike("001-A") // key like an id where the value is matched by the following example
.stringType("description", "Some Description")
.closeObject()
.closeObject()
.object("three")
.eachKeyMappedToAnArrayLike("001") // key like an id mapped to an array where each item is matched by the following example
.id("someId", 23456L)
.closeObject()
.closeArray()
.closeObject();
```
For an example, have a look at [WildcardKeysTest](../pact-jvm-consumer-junit/src/test/java/au/com/dius/pact/consumer/WildcardKeysTest.java).
**NOTE:** The `eachKeyLike` 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 `eachKeyLike` condition
applied to a map will result in only one being applied when the pact is verified (probably the last).
**Further Note: From version 3.5.22 onwards pacts with wildcards applied to map keys will require the Java system property
"pact.matching.wildcard" set to value "true" when the pact file is verified.**
### Matching on paths
You can use regular expressions to match incoming requests. The DSL has a `matchPath` method for this. You can provide
a real path as a second value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.matchPath("/transaction/[0-9]+") // or .matchPath("/transaction/[0-9]+", "/transaction/1234567890")
.method("POST")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```
### Matching on headers
You can use regular expressions to match request and response headers. The DSL has a `matchHeader` method for this. You can provide
an example header value to use when generating requests and responses, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchHeader("testreqheader", "test.*value")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
.matchHeader("Location", ".*/hello/[0-9]+", "/hello/1234")
```
### Matching on query parameters
You can use regular expressions to match request query parameters. The DSL has a `matchQuery` method for this. You can provide
an example value to use when generating requests, and if you leave it out it will generate a random one
from the regular expression.
For example:
```java
.given("test state")
.uponReceiving("a test interaction")
.path("/hello")
.method("POST")
.matchQuery("a", "\\d+", "100")
.matchQuery("b", "[A-Z]", "X")
.body("{\"name\": \"harry\"}")
.willRespondWith()
.status(200)
.body("{\"hello\": \"harry\"}")
```
# Forcing pact files to be overwritten (3.6.5+)
By default, when the pact file is written, it will be merged with any existing pact file. To force the file to be
overwritten, set the Java system property `pact.writer.overwrite` to `true`.
# Having values injected from provider state callbacks (3.6.11+)

For example, assume that an API call is made to get the details of a user by ID. A provider state can be defined that
specifies that the user must be exist, but the ID will be created when the user is created. So we can then define an
expression for the path where the ID will be replaced with the value returned from the provider state callback.
```java
.pathFromProviderState("/api/users/${id}", "/api/users/100")
```

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-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>

<!-- You can define as many as you need, but each must have a unique name -->

```
### 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>
```
