Create service tests using Forge

    You can now create unit tests for SwitchYard services using a simple forge command : create-service-test.  This command is available once you install the "switchyard" facet in your forge project.  Generating a new test only requires a service name:

     

    switchyard create-service-test --serviceName MyService
    

     

    The service name passed in via --serviceName is not required to exist at the time the test is created.  Of course, the test will fail if you don't create a service with this name in the application.  The generated test class looks like this:

     

    @RunWith(SwitchYardRunner.class)
    @SwitchYardTestCaseConfig(mixins=CDIMixIn.class, config=SwitchYardTestCaseConfig.SWITCHYARD_XML)
    public class MyServiceTest {
    
        @ServiceOperation("MyService")
        private Invoker service;
    
        @Test
        public void sendMessage() {
            service.sendInOnly("Message content goes here!");
        }
    }
    
    

     

    The generated test class is just a starting point.  Here are some changes you might want to make to the generated test:

    • If you want to invoke a specific operation name on the service, then add it to the @ServiceOperation annotation.  For example, if you wanted to invoke the "process" operation on the "MyService" service, then the annotation value would be "MyService.process".
    • If the service operation is in-out then you will want to change the test method to invoke service.sendInOut().
    • Replace "Message content goes here!" with the actual payload for the message.
    • Consider the use of additional MixIns depending on what you are testing (BPM, transformation, web service, etc.).
    • Add more test methods!  You can have as many as you want per test class.
