Writing good unit tests is made much easier by **dependency injection**. This lets you separate your code's behavior from that of your dependencies. Many people use **mocks** to add dependencies to unit tests. I think this is usually a mistake.
Always interesting to hear different points of view on this subject. Personally I think mocks make sense to capture complex sets of interactions or otherwise difficult to reach error conditions, so I don't think it's a do or do-not kind of thing.

Mocking and dependency injection don't seem to be mutually exclusive, if anything dependency injection can make it easier to get the component you're testing to interface with the mock
