Thanks Lorin! That helps me quite a bit.

I think they're basically equivalent in terms of what you can do with them, but they use different styles: In mox the assertions are written before the code under test, and in mock the assertions are written after the code under test.

Also, Mock has been accepted into the Python 3.3(?) standard library as a submodule of unit tests. However, mox has been the main mocking library used in Nova unit test for as long as I have been familiar with the code.
