It has a single function in `consumer/src/consumer.js` that navigates the links from the provider to find the +orders resource, get all the orders, find the first one and execute the delete action. + +The consumer does the following: + +1. Get the root resource +2. Find the orders relation +3. Execute a GET to the URL of the orders relation +4. Extract the first order entity from the embedded entities +5. Find the delete action for that order +6. Execute the action (which executes a DELETE to the URL of the action) + +## Pact Tests + +The problem with using normal Pact tests to test this scenario is that Siren responses contain URLs to the resources and +actions. The URLs when running the consumer test will be different than those when verifying the provider. This will +result in a verification failure. + +To get round this problem, we use the `url` matcher function from the consumer Pact DSL. This function takes a list of +path fragments. The path fragments can be either plain strings or regular expressions. It then constructs +the actual URL to use in the consumer test using the mock servers base URL, and a regular expression matcher that can +match the URLs in the provider verification test. + +### Dealing with hypermedia formats like Siren actions + +Siren takes hypermedia links one step further by introducing resource actions. These encode the URL, HTTP method and +optionally any required parameters needed to make the requests for the actions supported by the resource. + +The problem could then arise that the consumer make only use a few actions provided by the provider. We would want to +ensure that these actions are present in the list for the resource, and ignore the ones we are not using. The other issue +is that our tests should not be dependent on the order of the actions. + +This is where the "array contains" matcher can help. It will allow us to match the resource actions for the ones we are +using, and ignore the others. It will also not depend on the order the actions are returned. + +This is the actions for the order resource in the provider: + +```json +{ + "actions": [ + { + "name": "update", + "method": "PUT", + "href": "http://localhost:8080/orders/6774860028109588394" + }, + { + "name": "delete", + "method": "DELETE", + "href": "http://localhost:8080/orders/6774860028109588394" + }, + { + "name": "changeStatus", + "method": "PUT", + "href": "http://localhost:8080/orders/6774860028109588394/status" + } + ] +} +``` + +For example, in the consumer test we can specify: + +```js +"actions": arrayContaining( + { + "name": "update", + "method": "PUT", + "href": url(["orders", regex("\\d+", "1234")]) + }, + { + "name": "delete", + "method": "DELETE", + "href": url(["orders", regex("\\d+", "1234")]) + } +) +``` + +This will match the actions if they contain the update and delete actions. it will ignore the other actions. + +You can see this in work if you remove one of the controller methods in the provider. For instance, if we commented out +the delete endpoint, and then run the pact verification in the provider, we get this error: + +```console +$ ./gradlew pactverify + +> Task :startServer + + . ____ _ __ _ _ + /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ +( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ + \\/ ___)| |_)| | | | | || (_| | ) ) ) ) + ' |____| .__|_| |_|_| |_\__, | / / / / + =========|_|==============|___/=/_/_/_/ + :: Spring Boot :: (v2.3.4.RELEASE) + +2020-11-09 14:53:32.046 INFO 39485 --- [ main] i.p.e.s.SirenProviderApplication : Starting SirenProviderApplication on ronald-P95xER with PID 39485 (/home/ronald/Development/Projects/Pact/example-siren/provider/build/libs/siren-provider-0.0.1.jar started by ronald in /home/ronald/Development/Projects/Pact/example-siren/provider) +2020-11-09 14:53:32.048 INFO 39485 --- [ main] i.p.e.s.SirenProviderApplication : No active profile set, falling back to default profiles: default +2020-11-09 14:53:32.797 INFO 39485 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat initialized with port(s): 8080 (http) +2020-11-09 14:53:32.808 INFO 39485 --- [ main] o.apache.catalina.core.StandardService : Starting service [Tomcat] +2020-11-09 14:53:32.808 INFO 39485 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet engine: [Apache Tomcat/9.0.38] +2020-11-09 14:53:32.870 INFO 39485 --- [ main] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext +2020-11-09 14:53:32.870 INFO 39485 --- [ main] w.s.c.ServletWebServerApplicationContext : Root WebApplicationContext: initialization completed in 759 ms +2020-11-09 14:53:33.071 INFO 39485 --- [ main] o.s.s.concurrent.ThreadPoolTaskExecutor : Initializing ExecutorService 'applicationTaskExecutor' +2020-11-09 14:53:33.221 INFO 39485 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8080 (http) with context path '' +2020-11-09 14:53:33.229 INFO 39485 --- [ main] i.p.e.s.SirenProviderApplication : Started SirenProviderApplication in 1.53 seconds (JVM running for 1.903) +java -jar /home/ronald/Development/Projects/Pact/example-siren/provider/build/libs/siren-provider-0.0.1.jar is ready. + +> Task :pactVerify_Siren_Order_Provider FAILED + +Verifying a pact between Siren Consumer and Siren Order Provider + [Using File /home/ronald/Development/Projects/Pact/example-siren/consumer/pacts/Siren Order Provider-Siren Order Service.json] + get root + returns a response which + has status code 200 (OK) + has a matching body (OK) + get all orders + returns a response which + has status code 200 (OK) + has a matching body (FAILED) + delete order + returns a response which + has status code 200 (FAILED) + has a matching body (OK) + +NOTE: Skipping publishing of verification results as it has been disabled (pact.verifier.publishResults is not 'true') + + +Failures: + +1) Verifying a pact between Siren Consumer and Siren Order Provider - get all orders + + 1.1) body: $.entities.0.actions Variant at index 1 ({"href":http://localhost:9000/orders/1234,"method":DELETE,"name":delete}) was not found in the actual list + + [ + { + - "href": "http://localhost:9000/orders/1234", + + "href": "http://localhost:8080/orders/7779028774458252624", + "method": "PUT", + "name": "update" + }, + { + - "href": "http://localhost:9000/orders/1234", + - "method": "DELETE", + - "name": "delete" + + "href": "http://localhost:8080/orders/7779028774458252624/status", + + "method": "PUT", + + "name": "changeStatus" + } + ] + + + 1.2) status: expected status of 200 but was 405 + + + +FAILURE: Build failed with an exception. + +* What went wrong: +There were 2 non-pending pact failures for provider Siren Order Provider + +* Try: +Run with --stacktrace option to get the stack trace.
