This file is part of the sulky modules. It's supposed to contain classes I'd like to see in commons-io. At the moment it only contains a TimeoutOutputStream that throws an IOException if a certain timeout is exceeded.

PatternTesting Exception (patterntesting-exception) is a framework round about exceptions. It wraps some common exception (like IOException) to provide some more information as the original exception (e.g. the filename with the absolute pathname). On the other it allows you to provoke exceptions for better testing.

# Pact Spring/JUnit runner ## Overview Library provides ability to play contract tests against a provider using Spring &amp; JUnit. This library is based on and references the JUnit package, so see the [Pact JUnit 4](../pact-jvm-provider-junit) or [Pact JUnit 5](../pact-jvm-provider-junit5) providers for more details regarding configuration using JUnit. Supports: - Standard ways to load pacts from folders and broker - Easy way to change assertion strategy - Spring Test MockMVC Controllers and ControllerAdvice using MockMvc standalone setup. - MockMvc debugger output - Multiple @State runs to test a particular Provider State multiple times - **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. **NOTE:** For publishing provider verification results to a pact broker, make sure the Java system property `pact.provider.version` is set with the version of your provider. ## Example of MockMvc test ```java @RunWith(RestPactRunner.class) // Custom pact runner, child of PactRunner which runs only REST tests @Provider(&quot;myAwesomeService&quot;) // Set up name of tested provider @PactFolder(&quot;pacts&quot;) // Point where to find pacts (See also section Pacts source in documentation) public class ContractTest { //Create an instance of your controller. We cannot autowire this as we&apos;re not using (and don&apos;t want to use) a Spring test runner. @InjectMocks private AwesomeController awesomeController = new AwesomeController(); //Mock your service logic class. We&apos;ll use this to create scenarios for respective provider states. @Mock private AwesomeBusinessLogic awesomeBusinessLogic; //Create an instance of your controller advice (if you have one). This will be passed to the MockMvcTarget constructor to be wired up with MockMvc. @InjectMocks private AwesomeControllerAdvice awesomeControllerAdvice = new AwesomeControllerAdvice(); //Create a new instance of the MockMvcTarget and annotate it as the TestTarget for PactRunner @TestTarget public final MockMvcTarget target = new MockMvcTarget(); @Before //Method will be run before each test of interaction public void before() { //initialize your mocks using your mocking framework MockitoAnnotations.initMocks(this); //configure the MockMvcTarget with your controller and controller advice target.setControllers(awesomeController); target.setControllerAdvice(awesomeControllerAdvice); } @State(&quot;default&quot;, &quot;no-data&quot;) // Method will be run before testing interactions that require &quot;default&quot; or &quot;no-data&quot; state public void toDefaultState() { target.setRunTimes(3); //let&apos;s loop through this state a few times for a 3 data variants when(awesomeBusinessLogic.getById(any(UUID.class))) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.ONE)) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.TWO)) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.THREE)); } @State(&quot;error-case&quot;) public void SingleUploadExistsState_Success() { target.setRunTimes(1); //tell the runner to only loop one time for this state //you might want to throw exceptions to be picked off by your controller advice when(awesomeBusinessLogic.getById(any(UUID.class))) .then(i -&gt; { throw new NotCoolException(i.getArgumentAt(0, UUID.class).toString()); }); } } ``` ## Using a Spring runner (version 3.5.7+) You can use `SpringRestPactRunner` instead of the default Pact runner to use the Spring test annotations. This will allow you to inject or mock spring beans. For example: ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;pricing&quot;) @PactBroker(protocol = &quot;https&quot;, host = &quot;${pactBrokerHost}&quot;, port = &quot;443&quot;, authentication = @PactBrokerAuth(username = &quot;${pactBrokerUser}&quot;, password = &quot;${pactBrokerPassword}&quot;)) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT) public class PricingServiceProviderPactTest { @MockBean private ProductClient productClient; // This will replace the bean with a mock in the application context @TestTarget @SuppressWarnings(value = &quot;VisibilityModifier&quot;) public final Target target = new HttpTarget(8091); @State(&quot;Product X010000021 exists&quot;) public void setupProductX010000021() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode(&quot;X010000021&quot;); when(productClient.fetch((Set&lt;String&gt;) argThat(contains(&quot;X010000021&quot;)), any())).thenReturn(product); } @State(&quot;the product code X00001 can be priced&quot;) public void theProductCodeX00001CanBePriced() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode(&quot;X00001&quot;); when(productClient.find((Set&lt;String&gt;) argThat(contains(&quot;X00001&quot;)), any())).thenReturn(product); } } ``` ### Using Spring Context Properties (version 3.5.14+) From version 3.5.14 onwards, the SpringRestPactRunner will look up any annotation expressions (like `${pactBrokerHost}`) above) from the Spring context. For Springboot, this will allow you to define the properties in the application test properties. For instance, if you create the following `application.yml` in the test resources: ```yaml pactbroker: host: &quot;your.broker.local&quot; port: &quot;443&quot; protocol: &quot;https&quot; auth: username: &quot;&lt;your broker username&gt;&quot; password: &quot;&lt;your broker password&gt;&quot; ``` Then you can use the defaults on the `@PactBroker` annotation. ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;My Service&quot;) @PactBroker( authentication = @PactBrokerAuth(username = &quot;${pactbroker.auth.username}&quot;, password = &quot;${pactbroker.auth.password}&quot;) ) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { ``` ### Using a random port with a Springboot test (version 3.5.14+) If you use a random port in a springboot test (by setting `SpringBootTest.WebEnvironment.RANDOM_PORT`), you can use the `SpringBootHttpTarget` which will get the application port from the spring application context. For example: ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;My Service&quot;) @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @TestTarget public final Target target = new SpringBootHttpTarget(); } ```

pact-jvm-consumer-junit5 ======================== JUnit 5 support for Pact consumer tests ## Dependency The library is available on maven central using: * group-id = `au.com.dius` * artifact-id = `pact-jvm-consumer-junit5_2.12` * version-id = `3.6.x` ## Usage ### 1. Add the Pact consumer test extension to the test class. To write Pact consumer tests with JUnit 5, you need to add `@ExtendWith(PactConsumerTestExt)` to your test class. This replaces the `PactRunner` used for JUnit 4 tests. The rest of the test follows a similar pattern as for JUnit 4 tests. ```java @ExtendWith(PactConsumerTestExt.class) class ExampleJavaConsumerPactTest { ``` ### 2. create a method annotated with `@Pact` that returns the interactions for the test For each test (as with JUnit 4), you need to define a method annotated with the `@Pact` annotation that returns the interactions for the test. ```java @Pact(provider=&quot;ArticlesProvider&quot;, consumer=&quot;test_consumer&quot;) public RequestResponsePact createPact(PactDslWithProvider builder) { return builder .given(&quot;test state&quot;) .uponReceiving(&quot;ExampleJavaConsumerPactTest test interaction&quot;) .path(&quot;/articles.json&quot;) .method(&quot;GET&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;responsetest\&quot;: true}&quot;) .toPact(); } ``` ### 3. Link the mock server with the interactions for the test with `@PactTestFor` Then the final step is to use the `@PactTestFor` annotation to tell the Pact extension how to setup the Pact test. You can either put this annotation on the test class, or on the test method. For examples see [ArticlesTest](src/test/java/au/com/dius/pact/consumer/junit5/ArticlesTest.java) and [MultiTest](src/test/groovy/au/com/dius/pact/consumer/junit5/MultiTest.groovy). The `@PactTestFor` annotation allows you to control the mock server in the same way as the JUnit 4 `PactProviderRule`. It allows you to set the hostname to bind to (default is `localhost`) and the port (default is to use a random port). You can also set the Pact specification version to use (default is V3). ```java @ExtendWith(PactConsumerTestExt.class) @PactTestFor(providerName = &quot;ArticlesProvider&quot;) public class ExampleJavaConsumerPactTest { ``` **NOTE on the hostname**: The mock server runs in the same JVM as the test, so the only valid values for hostname are: | hostname | result | | -------- | ------ | | `localhost` | binds to the address that localhost points to (normally the loopback adapter) | | `127.0.0.1` or `::1` | binds to the loopback adapter | | host name | binds to the default interface that the host machines DNS name resolves to | | `0.0.0.0` or `::` | binds to the all interfaces on the host machine | #### Matching the interactions by provider name If you set the `providerName` on the `@PactTestFor` annotation, then the first method with a `@Pact` annotation with the same provider name will be used. See [ArticlesTest](src/test/java/au/com/dius/pact/consumer/junit5/ArticlesTest.java) for an example. #### Matching the interactions by method name If you set the `pactMethod` on the `@PactTestFor` annotation, then the method with the provided name will be used (it still needs a `@Pact` annotation). See [MultiTest](src/test/groovy/au/com/dius/pact/consumer/junit5/MultiTest.groovy) for an example. ### Injecting the mock server into the test You can get the mock server injected into the test method by adding a `MockServer` parameter to the test method. ```java @Test void test(MockServer mockServer) throws IOException { HttpResponse httpResponse = Request.Get(mockServer.getUrl() + &quot;/articles.json&quot;).execute().returnResponse(); assertThat(httpResponse.getStatusLine().getStatusCode(), is(equalTo(200))); } ``` This helps with getting the base URL of the mock server, especially when a random port is used. ## Changing the directory pact files are written to By default, pact files are written to `target/pacts` (or `build/pacts` if you use Gradle), but this can be overwritten with the `pact.rootDir` system property. This property needs to be set on the test JVM as most build tools will fork a new JVM to run the tests. For Gradle, add this to your build.gradle: ```groovy test { systemProperties[&apos;pact.rootDir&apos;] = &quot;$buildDir/custom-pacts-directory&quot; } ``` For maven, use the systemPropertyVariables configuration: ```xml &lt;project&gt; [...] &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-surefire-plugin&lt;/artifactId&gt; &lt;version&gt;2.18&lt;/version&gt; &lt;configuration&gt; &lt;systemPropertyVariables&gt; &lt;pact.rootDir&gt;some/other/directory&lt;/pact.rootDir&gt; &lt;buildDirectory&gt;${project.build.directory}&lt;/buildDirectory&gt; [...] &lt;/systemPropertyVariables&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; [...] &lt;/project&gt; ``` For SBT: ```scala fork in Test := true, javaOptions in Test := Seq(&quot;-Dpact.rootDir=some/other/directory&quot;) ``` ### Using `@PactFolder` annotation [3.6.2+] You can override the directory the pacts are written in a test by adding the `@PactFolder` annotation to the test class. ## 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`. ## Unsupported The current implementation does not support tests with multiple providers. This will be added in a later release. # 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 all you to set an expression that will be parsed with the values returned from the provider states: For JSON bodies, use `valueFromProviderState`.&lt;br/&gt; For headers, use `headerFromProviderState`.&lt;br/&gt; For query parameters, use `queryParameterFromProviderState`.&lt;br/&gt; 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(&quot;/api/users/${id}&quot;, &quot;/api/users/100&quot;) ``` You can also just use the key instead of an expression: ```java .valueFromProviderState(&apos;userId&apos;, &apos;userId&apos;, 100) // will look value using userId as the key ```

This will be passed to the MockMvcTarget constructor to be wired up with MockMvc. @InjectMocks private AwesomeControllerAdvice awesomeControllerAdvice = new AwesomeControllerAdvice(); //Create a new instance of the MockMvcTarget and annotate it as the TestTarget for PactRunner @TestTarget public final MockMvcTarget target = new MockMvcTarget(); @Before //Method will be run before each test of interaction public void before() { //initialize your mocks using your mocking framework MockitoAnnotations.initMocks(this); //configure the MockMvcTarget with your controller and controller advice target.setControllers(awesomeController); target.setControllerAdvice(awesomeControllerAdvice); } @State(&quot;default&quot;, &quot;no-data&quot;) // Method will be run before testing interactions that require &quot;default&quot; or &quot;no-data&quot; state public void toDefaultState() { target.setRunTimes(3); //let&apos;s loop through this state a few times for a 3 data variants when(awesomeBusinessLogic.getById(any(UUID.class))) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.ONE)) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.TWO)) .thenReturn(myTestHelper.generateRandomReturnData(UUID.randomUUID(), ExampleEnum.THREE)); } @State(&quot;error-case&quot;) public void SingleUploadExistsState_Success() { target.setRunTimes(1); //tell the runner to only loop one time for this state //you might want to throw exceptions to be picked off by your controller advice when(awesomeBusinessLogic.getById(any(UUID.class))) .then(i -&gt; { throw new NotCoolException(i.getArgumentAt(0, UUID.class).toString()); }); } } ``` ## Using Spring runners You can use `SpringRestPactRunner` or `SpringMessagePactRunner` instead of the default Pact runner to use the Spring test annotations. This will allow you to inject or mock spring beans. `SpringRestPactRunner` is for restful webapps and `SpringMessagePactRunner` is for async message tests. For example: ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;pricing&quot;) @PactBroker(protocol = &quot;https&quot;, host = &quot;${pactBrokerHost}&quot;, port = &quot;443&quot;, authentication = @PactBrokerAuth(username = &quot;${pactBrokerUser}&quot;, password = &quot;${pactBrokerPassword}&quot;)) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT) public class PricingServiceProviderPactTest { @MockBean private ProductClient productClient; // This will replace the bean with a mock in the application context @TestTarget @SuppressWarnings(value = &quot;VisibilityModifier&quot;) public final Target target = new HttpTarget(8091); @State(&quot;Product X010000021 exists&quot;) public void setupProductX010000021() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode(&quot;X010000021&quot;); when(productClient.fetch((Set&lt;String&gt;) argThat(contains(&quot;X010000021&quot;)), any())).thenReturn(product); } @State(&quot;the product code X00001 can be priced&quot;) public void theProductCodeX00001CanBePriced() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode(&quot;X00001&quot;); when(productClient.find((Set&lt;String&gt;) argThat(contains(&quot;X00001&quot;)), any())).thenReturn(product); } } ``` ### Using Spring Context Properties The SpringRestPactRunner will look up any annotation expressions (like `${pactBrokerHost}`) above) from the Spring context. For Springboot, this will allow you to define the properties in the application test properties. For instance, if you create the following `application.yml` in the test resources: ```yaml pactbroker: host: &quot;your.broker.local&quot; port: &quot;443&quot; protocol: &quot;https&quot; auth: username: &quot;&lt;your broker username&gt;&quot; password: &quot;&lt;your broker password&gt;&quot; ``` Then you can use the defaults on the `@PactBroker` annotation. ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;My Service&quot;) @PactBroker( authentication = @PactBrokerAuth(username = &quot;${pactbroker.auth.username}&quot;, password = &quot;${pactbroker.auth.password}&quot;) ) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { ``` ### Using a random port with a Springboot test If you use a random port in a springboot test (by setting `SpringBootTest.WebEnvironment.RANDOM_PORT`), you need to set it to the `TestTarget`. How this works is different for JUnit4 and JUnit5. #### JUnit4 You can use the `SpringBootHttpTarget` which will get the application port from the spring application context. For example: ```java @RunWith(SpringRestPactRunner.class) @Provider(&quot;My Service&quot;) @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @TestTarget public final Target target = new SpringBootHttpTarget(); } ``` #### JUnit5 You actually don&apos;t need to dependend on `pact-jvm-provider-spring` for this. It&apos;s sufficient to depend on `pact-jvm-provider-junit5`. You can set the port to the `HttpTestTarget` object in the before method. ```java @Provider(&quot;My Service&quot;) @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @LocalServerPort private int port; @BeforeEach void before(PactVerificationContext context) { context.setTarget(new HttpTestTarget(&quot;localhost&quot;, port)); } } ```

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(&quot;Some Consumer&quot;) .hasPactWith(&quot;Some Provider&quot;) .uponReceiving(&quot;a request to say Hello&quot;) .path(&quot;/hello&quot;) .method(&quot;POST&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) .toFragment(); MockProviderConfig config = MockProviderConfig.createDefault(); VerificationResult result = pactFragment.runConsumer(config, new TestRun() { @Override public void run(MockProviderConfig config) { Map expectedResponse = new HashMap(); expectedResponse.put(&quot;hello&quot;, &quot;harry&quot;); try { assertEquals(new ProviderClient(config.url()).hello(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;), 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(&quot;Some Consumer&quot;) .hasPactWith(&quot;Some Provider&quot;) .given(&quot;a certain state on the provider&quot;) .uponReceiving(&quot;a request for something&quot;) .path(&quot;/hello&quot;) .method(&quot;POST&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) .uponReceiving(&quot;another request for something&quot;) .path(&quot;/hello&quot;) .method(&quot;POST&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) . . . .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(&quot;name&quot;) .booleanType(&quot;happy&quot;) .hexValue(&quot;hexCode&quot;) .id() .ipAddress(&quot;localAddress&quot;) .numberValue(&quot;age&quot;, 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(&quot;users&quot;) .id() .stringType(&quot;name&quot;) .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(&quot;Some Consumer&quot;) .hasPactWith(&quot;Some Provider&quot;) .uponReceiving(&quot;a request for a basic JSON value&quot;) .path(&quot;/hello&quot;) .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(&quot;clearedDate&quot;, &quot;mm/dd/yyyy&quot;, date) .stringType(&quot;status&quot;, &quot;STATUS&quot;) .decimalType(&quot;amount&quot;, 100.0) .closeObject() ``` This will then match a body like: ```json [ { &quot;clearedDate&quot; : &quot;07/22/2015&quot;, &quot;status&quot; : &quot;C&quot;, &quot;amount&quot; : 15.0 }, { &quot;clearedDate&quot; : &quot;07/22/2015&quot;, &quot;status&quot; : &quot;C&quot;, &quot;amount&quot; : 15.0 }, { &quot;clearedDate&quot; : &quot;07/22/2015&quot;, &quot;status&quot; : &quot;C&quot;, &quot;amount&quot; : 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(&quot;type&quot;,&quot;FeatureCollection&quot;) .eachLike(&quot;features&quot;) .stringType(&quot;type&quot;,&quot;Feature&quot;) .object(&quot;geometry&quot;) .stringType(&quot;type&quot;,&quot;Point&quot;) .eachArrayLike(&quot;coordinates&quot;) // coordinates is an array of arrays .decimalType(-7.55717) .decimalType(49.766896) .closeArray() .closeArray() .closeObject() .object(&quot;properties&quot;) .stringType(&quot;prop0&quot;,&quot;value0&quot;) .closeObject() .closeObject() .closeArray() ``` This generated the following JSON: ```json { &quot;features&quot;: [ { &quot;geometry&quot;: { &quot;coordinates&quot;: [[-7.55717, 49.766896]], &quot;type&quot;: &quot;Point&quot; }, &quot;type&quot;: &quot;Feature&quot;, &quot;properties&quot;: { &quot;prop0&quot;: &quot;value0&quot; } } ], &quot;type&quot;: &quot;FeatureCollection&quot; } ``` 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(&quot;one&quot;) .eachKeyLike(&quot;001&quot;, PactDslJsonRootValue.id(12345L)) // key like an id mapped to a matcher .closeObject() .object(&quot;two&quot;) .eachKeyLike(&quot;001-A&quot;) // key like an id where the value is matched by the following example .stringType(&quot;description&quot;, &quot;Some Description&quot;) .closeObject() .closeObject() .object(&quot;three&quot;) .eachKeyMappedToAnArrayLike(&quot;001&quot;) // key like an id mapped to an array where each item is matched by the following example .id(&quot;someId&quot;, 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(&quot;test state&quot;) .uponReceiving(&quot;a test interaction&quot;) .matchPath(&quot;/transaction/[0-9]+&quot;) // or .matchPath(&quot;/transaction/[0-9]+&quot;, &quot;/transaction/1234567890&quot;) .method(&quot;POST&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) ``` ### 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(&quot;test state&quot;) .uponReceiving(&quot;a test interaction&quot;) .path(&quot;/hello&quot;) .method(&quot;POST&quot;) .matchHeader(&quot;testreqheader&quot;, &quot;test.*value&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) .matchHeader(&quot;Location&quot;, &quot;.*/hello/[0-9]+&quot;, &quot;/hello/1234&quot;) ``` ### 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(&quot;test state&quot;) .uponReceiving(&quot;a test interaction&quot;) .path(&quot;/hello&quot;) .method(&quot;POST&quot;) .matchQuery(&quot;a&quot;, &quot;\\d+&quot;, &quot;100&quot;) .matchQuery(&quot;b&quot;, &quot;[A-Z]&quot;, &quot;X&quot;) .body(&quot;{\&quot;name\&quot;: \&quot;harry\&quot;}&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;hello\&quot;: \&quot;harry\&quot;}&quot;) ```
