Interaction Testing

I am a fan of unit tests. From the first time I saw them I have been selling their benefits.

Up until this time I have not used a mock objects framework. It is time. I am considering NMock2 and Rhino Mock.

Oren Eini, author of Rhino Mock, has some good feedback on how to use a mock library effectively in his post Guidelines to Using Interaction Based Testing. I had not thought about the distinction between fake and mock objects.
