Summary

Mock is a very powerful and flexible object, but it suffers from a flaw which is general to mocking. If you refactor some of your code, rename members and so on, any tests for code that is still using the old api but uses mocks instead of the real objects will still pass. This means your tests can all pass even though your code is broken.
