If you're writing lots of mocks, odds are you're writing a lot of unit tests. In my experience these are rarely useful. Most often they are either really testing a compiler's output (indirectly), supplying an ad-hoc and incomplete type checking system to a dynamic language, or more appropriately covered by asserts that will scream when integration tests fail.
