Mocking Object issue

Question

I am trying to make following mocking

var checkComponent = MockRepository.GenerateStub<IController>();

checkComponent.Stub(r => r.GetSelector().Select(new Position(3,6,1))).Return(true);

I am getting that r.GetSelector() is returning null.

Is there a way to make mocking that i am trying to create ?

Thanks.

Answer 1

I am getting that r.GetSelector() is returning null.

This is because checkComponent (r in Stub() call) is not a real implementation of the IController it is basically RhinoMock proxy object which implements IController interface.

You have to specify what should be returned when GetSelector() is called, use Mock for scenarios when you need to specify expectations on methods.

var componentMock = MockRepository.GenerateMock<IController>();
var selectorMock = MockRepository.GenerateMock<ISelector>();

// if you need - specify concrete arguments to return true
selectorMock.Expect(x => x.Select(null)).IgnoreArguments().Return(true).Repeat.Any();
componentMock.Expect(x => x.GetSelector()).Return(selectorMock).Repeat.Any();
