Grails 2.0.0模拟服务始终返回true吗？

Question

I have a service in my controller I'm trying to mock but it always returns true. The service looks like this:

def someService (x, y){...}

Then I mocked it in my controller test: mockservice.demand.someService () {-> return false }

It keeps returning true. I don't know what's wrong. I tried including the parameters but its still not returning false. How to do this?

PS: Forgive the typos, I am on my phone right now. Thanks

Answer 1

I'm assuming that you're using this service in an controller, and the unit test is from the controller. I'm assuming also that you read mocking collaborators in the docs.

@TestFor(MyController)
class MyControllerSpec {
  def setup() {
    def mockServiceControl = mockFor(SomeService)
    //here you limit the amount of times that the method should be called.
    mockServiceControl.demand.someService(0..1) { x, y ->
      return false
    }
    //probably you're missing to assign the attribute in the controller
    controller.someService = mockServiceControl.createMock()
  }

  void testSomething() {
    controller.action()

    //assert response

    //Then verify that the demand mocking is correct
    mockServiceControl.verify()
  }
}
