Fudge is a Python module for using fake objects (mocks and stubs) to test real ones.
In readable Python code, you declare what methods are available on your fake and
how they should be called. Then you inject that into your application and start
testing. This declarative approach means you don't have to record and playback
actions and you don't have to inspect your fakes after running code. If the fake
object was used incorrectly then you'll see an informative exception message
with a traceback that points to the culprit.
