Question

Is there a way to test this interceptor? It’s being ignored in my test.

Code:

class BaseDomainController {
    def beforeInterceptor = {
        throw new RuntimeException()
        if(!isAdmin()){
            redirect(controller: 'login', action: 'show')
            return
        }
    }
}

class BaseDomainControllerSpec extends IntegrationSpec{

    BaseDomainController controller = new BaseDomainController()

    def 'some test'(){
        given: 
            controller.index()
        expect:
            thrown(RuntimeException)
    }

}

According to this thread http://grails.1312388.n4.nabble.com/Controller-interceptors-and-unit-tests-td1326852.html Graeme indicates you have to call the interceptor separately. In our case, since we are using the interceptor to check a token, and it’s the same for every action, we used:

@Before
void setUp() 
{
    super.setUp();
    controller.params.token = "8bf062eb-ec4e-44ae-8872-23fad8eca2ce"
    if (!controller.beforeInterceptor())
    {
        fail("beforeInterceptor failed");
    }    
} 

I guess if each unit test specifies different arguments for the interceptor, you’ll have to call it separately each time. If don’t want to to this, I think you have to use something like the Grail’s functional testing, which will go through the entire lifecycle: http://grails.org/plugin/functional-test
