模拟服务和Grails jaxrs集成测试

Question

I want to test a grails application(using jaxrs) and it's integrations. For this task I hope to use the awesome IntegrationTestCase-class from the jaxrs plugin. This is challenging because I want to mock/replace a service within my application. With “pure” Spring I would create testcontext and manually wire up the mock. I have no idea how to do this in grails. I've tried to access the ApplicationContext directly

Holders.grailsApplication.mainContext.registerMockBean("myService", new MyMock())

This does not seem to work as the mock is not used during the test. Any ideas?

Answer 1

Try to define in test class his way:

    @Before
    void before() {
        Holders.grailsApplication = grailsApplication

        defineBeans {
            myService(MyMock)
        }
    }

It's for jUnit tests. If you use Spock, rename before() to setup() and see Spock basics Fixture Methods.
