Fudge is a Python module for using fake objects (mocks, stubs, etc) to test 
real ones.

This module is designed for two specific situations:
    * Replace an object
          o Temporarily return a canned value for a method or allow a method 
            to be called without affect.
    * Ensure an object is used correctly
          o Declare expectations about what methods should be called and what 
            arguments should be sent.

Fudge was inspired by Mocha which is a simpler version of jMock. But unlike 
Mocha, Fudge does not automatically hijack real objects; you explicitly patch 
them in your test setup. And unlike jMock, Fudge is only as strict about 
expectations as you want it to be. If you just want to expect a method call 
without worrying about its arguments or the type of the arguments then you 
can.
