This subproject is an extension of the Struts tag library. Each JSP custom tag in this library is a subclass of an associated tag in the Struts tag library. One difference is that this tag library does not use "rtexprvalues", it uses the expression evaluation engine in the Jakarta Taglibs implementation of the JSP Standard Tag Library (version 1.0) to evaluate attribute values. In addition, some of the Struts tags were not ported to this library, as it was determined that their functionality was entirely supplied by the JSTL. These particular Struts tags, and the reason for their non-porting will be described in the documentation for this library. In order to fully understand the correct utilization of this library, you must understand the use and operation of the Struts tag library, and the use and operation of the JavaServer Pages Standard Tag Library (hereafter called the "JSTL"), along with the expression language (sometimes called the "EL") used for evaluating attribute values.

This is an implementation of the Neural Gas algorithm on distance data (Relational Neural Gas) for unsupervised clustering. We recommend that you use the functions provided by the RelationalNeuralGas class for your purposes. All other classes and functions are utilities which are used by this central class. In particular, you can use RelationalNeuralGas.train() to obtain a RNGModel (i.e. a clustering of your data), and subsequently you can use RelationalNeuralGas.getAssignments() to obtain the resulting cluster assignments, and RelationalNeuralGas.classify() to cluster new points which are not part of the training data set. The underlying scientific work is summarized nicely in the dissertation "Topographic Mapping of Dissimilarity Datasets" by Alexander Hasenfuss (2009). The basic properties of an Relational Neural Gas algorithm are the following: 1.) It is relational: The data is represented only in terms of a pairwise distance matrix. 2.) It is a clustering method: The algorithm provides a clustering model, that is: After calculation, each data point should be assigned to a cluster (for this package here we only consider hard clustering, that is: each data point is assigned to exactly one cluster). 3.) It is a vector quantization method: Each cluster corresponds to a prototype, which is in the center of the cluster and data points are assigned to the cluster if and only if they are closest to this particular prototype. 4.) It is rank-based: The updates of the prototypes depend only on the distance ranking, not on the absolute value of the distances.

Races the cross validation error of competing attribute subsets. Use in conjuction with a ClassifierSubsetEval. RaceSearch has four modes: forward selection races all single attribute additions to a base set (initially no attributes), selects the winner to become the new base set and then iterates until there is no improvement over the base set. Backward elimination is similar but the initial base set has all attributes included and races all single attribute deletions. Schemata search is a bit different. Each iteration a series of races are run in parallel. Each race in a set determines whether a particular attribute should be included or not---ie the race is between the attribute being "in" or "out". The other attributes for this race are included or excluded randomly at each point in the evaluation. As soon as one race has a clear winner (ie it has been decided whether a particular attribute should be inor not) then the next set of races begins, using the result of the winning race from the previous iteration as new base set. Rank race first ranks the attributes using an attribute evaluator and then races the ranking. The race includes no attributes, the top ranked attribute, the top two attributes, the top three attributes, etc. It is also possible to generate a raked list of attributes through the forward racing process. If generateRanking is set to true then a complete forward race will be run---that is, racing continues until all attributes have been selected. The order that they are added in determines a complete ranking of all the attributes. Racing uses paired and unpaired t-tests on cross-validation errors of competing subsets. When there is a significant difference between the means of the errors of two competing subsets then the poorer of the two can be eliminated from the race. Similarly, if there is no significant difference between the mean errors of two competing subsets and they are within some threshold of each other, then one can be eliminated from the race.

# Pact Spring/JUnit runner ## Overview Library provides ability to play contract tests against a provider using Spring & 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("myAwesomeService") // Set up name of tested provider @PactFolder("pacts") // 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're not using (and don't want to use) a Spring test runner. @InjectMocks private AwesomeController awesomeController = new AwesomeController(); //Mock your service logic class. We'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("default", "no-data") // Method will be run before testing interactions that require "default" or "no-data" state public void toDefaultState() { target.setRunTimes(3); //let'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("error-case") 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 -> { 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("pricing") @PactBroker(protocol = "https", host = "${pactBrokerHost}", port = "443", authentication = @PactBrokerAuth(username = "${pactBrokerUser}", password = "${pactBrokerPassword}")) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT) public class PricingServiceProviderPactTest { @MockBean private ProductClient productClient; // This will replace the bean with a mock in the application context @TestTarget @SuppressWarnings(value = "VisibilityModifier") public final Target target = new HttpTarget(8091); @State("Product X010000021 exists") public void setupProductX010000021() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode("X010000021"); when(productClient.fetch((Set<String>) argThat(contains("X010000021")), any())).thenReturn(product); } @State("the product code X00001 can be priced") public void theProductCodeX00001CanBePriced() throws IOException { reset(productClient); ProductBuilder product = new ProductBuilder() .withProductCode("X00001"); when(productClient.find((Set<String>) argThat(contains("X00001")), any())).thenReturn(product); } } ``` ### Using Spring Context Properties (version 3.5.14+) From version 3.5.14 onwards, the SpringRestPactRunner will look up any annotation expressions (like `${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: "your.broker.local" port: "443" protocol: "https" auth: username: "<your broker username>" password: "<your broker password>" ``` Then you can use the defaults on the `@PactBroker` annotation. ```java @RunWith(SpringRestPactRunner.class) @Provider("My Service") @PactBroker( authentication = @PactBrokerAuth(username = "${pactbroker.auth.username}", password = "${pactbroker.auth.password}") ) @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("My Service") @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @TestTarget public final Target target = new SpringBootHttpTarget(); } ```

# 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 instance, if you create the following `application.yml` in the test resources: ```yaml pactbroker: host: "your.broker.local" port: "443" protocol: "https" auth: username: "<your broker username>" password: "<your broker password>" ``` Then you can use the defaults on the `@PactBroker` annotation. ```java @RunWith(SpringRestPactRunner.class) @Provider("My Service") @PactBroker( authentication = @PactBrokerAuth(username = "${pactbroker.auth.username}", password = "${pactbroker.auth.password}") ) @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("My Service") @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @TestTarget public final Target target = new SpringBootHttpTarget(); } ``` #### JUnit5 You actually don't need to dependend on `pact-jvm-provider-spring` for this. It's sufficient to depend on `pact-jvm-provider-junit5`. You can set the port to the `HttpTestTarget` object in the before method. ```java @Provider("My Service") @PactBroker @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class PactVerificationTest { @LocalServerPort private int port; @BeforeEach void before(PactVerificationContext context) { context.setTarget(new HttpTestTarget("localhost", port)); } } ```

# Leiningen plugin to verify a provider 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 "4.0.0" :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 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 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" } } } } } ```
