Sorry to be that late, I was in holiday :-)
Arg is designed to take the arguments type as generic argument. So you
have to use Arg<MessageBase>. But then, you can't use the lamda for
the property constraint.
With the classic property constraint it works:
// Arrange
IServiceBus serviceBus = MockRepository.GenerateStub<IServiceBus>();
serviceBus.Stub(
x => x.Send(Arg<MessageBase>.Matches(
Property.Value("Value", 2)
&& Is.TypeOf<Message2>())))
.Return(2);
serviceBus.Stub(x => x.Send(Arg<Message1>.Is.TypeOf))
.Return(1);
serviceBus.Expect(
x => x.Send(Arg<MessageBase>.Matches(
Property.Value("Value", "Success")
&& Is.TypeOf<Message1>())));
ClassUnderTest cut = new ClassUnderTest(serviceBus);
cut.DoMyThing();
serviceBus.VerifyAllExpectations();
AssertWasCalled also didn't work. I don't know why, probably it does
not consider the constraints correctly.
So there are two separate problems.
- Arg<T> should implicitly constrain for TypeOf<T>, and the lamda will
most probably work.
- AssertWasCalled should probably consider the constraints.
