How to Mock RoutedEventArgs.OrginalSource

[Vamsi Nudurupati]

Hi,

I am trying to Mock the OriginalSource in the RoutedEventArgs using Rhino Mocks. Can any one please suggest on how to make this test pass as the OriginalSource is null so the test fails as its not able to Convert the EventArgs to ViewModel?

[Test]

        public void Covert_ShouldReturnViewModel_WhenArgsIsPassed()

        {

            

            var routedEventArgs = MockRepository.GenerateStub<RoutedEventArgs>();

   var mockOriginalSource = routedEventArgs.Expect(eArgs => eArgs.OriginalSource).Return("test mock");

            var ViewModel = MockRepository.GenerateStub<ViewModel>();

            

            var eventArgsConverterHelper = MockRepository.GenerateMock<EventArgsConverterHelper>();

            eventArgsConverterHelper.Stub(

                eArgs => eArgs.GetCallReasonViewModelMethod(mockOriginalSource))

                .Return(callReasonViewModel)

                .Repeat.Once();

            var dTEventArgs = new EventArgsConverter();

            Assert.That(dTEventArgs.Convert(routedEventArgs), Is.EqualTo(ViewModel));

        }

thanks,

Vamsi

Unfortunately, OriginalSource is not virtual so you can't mock it with Rhino.Mocks.

Hi,

I think for your test it wouldn't make sense to use a mocked RoutedEventArgs object at all - why couldn't you just use a real RoutedEventArgs object?
