Verifying generic method called using Moq

Question

I\'m having trouble verifying that mock of IInterface.SomeMethod(T arg) was called using Moq.Mock.Verify.

I\'m can verify that met

Answer 1

I'm going to wing it. Since GenericMethod<T> requires that a T argument be provided, would it be possible to do:

mockInterface.Verify(serviceInterface => serviceInterface.GenericMethod(It.Is<object>(x=> typeof(ISpecificCommand).IsAssignableFrom(x.GetType()))), Times.Once());

Answer 2

It is a known issue in the Moq 4.0.10827 which is a current release version. See this discussion at GitHub https://github.com/Moq/moq4/pull/25. I have downloaded its dev branch, compiled and referenced it and now your test passes.
