MiniMock does, if you use it with doctests. MiniMock is super simple
- it just prints out every method call to the mock objects. You don't
have to set up expectations ahead of time, although you do have to
tell it what the mocked functions should return (otherwise the code
under test wouldn't be fooled!) If you use it in a doctest, the
printed method calls will have to match what appears in the doctest.
So the "verification" step just falls out for free - it just becomes
another part of the doctest's expected output.
