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

# 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" } } } } } ```

# 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" } } } } } ```
