How to assert that an action was called

Question

I need to asset an action called by a mock component.

 public interface IDispatcher
    {
     void Invoke(Action action);
    }

    public interface IDial

You need first to put an expectation on your mock. For example I want to test that Invoke is called only once and that I don't care about the incoming parameters.

mockDispatcher.Expect(m => m.Invoke(null)).IgnoreArguments().Repeat.Once();

Then you have to assert and verify your expectations

mockDispatcher.VerifyAllExpectations();

you can do it the same way for the second mock, however it's a not good practice to have two mocks per unit test. You should test each in different tests.
