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

Pact 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\"}") ```

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 above. If your favourite framework is not implemented, this module should give you all the hooks you need. Please let us know if you build one and we'll link to you from the main page.

Plugin for assisting with running Cucumber-JVM features in parallel

Pact model ========== The model project is responsible for providing: * a model to represent pacts * serialization and deserialization * comparison between two parts of the pact model * conversion between the pact model and whatever third party libraries used by the pact-consumer and pact-provider requires You should never need to include this project directly

Firebase JVM Client

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