The term 'Mock Objects' has become a popular one to describe special case objects that mimic real objects for testing. However the term mock was not originally meant as a more catchy name for stub, but to introduce a different approach to unit testing. In this article I dig into this difference of style to explain the difference between the interaction-based testing style favored by mock object fans, and the more usual state-based testing style.
