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.
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. And unlike jMock, Fudge is only as strict about expectations as you want it to be. If the type of arguments sent to the fake method aren’t important then you don’t have to declare an expectation for them.
Just type:
$ pip install fudge
You can get the pip command here. Fudge requires Python 2.5 or higher.
As of version 0.9.5, Fudge supports Python 3. Just install distribute and type:
$ python3.x setup.py install
This step will convert the Fudge source code using the 2to3 tool.
