I previously submitted a patch (sf id 706590),
since I was following www.python.com's notes on how 
to contribute - since using sf more i think i should of 
added it to this RFE. Since posting the orignal patch I 
have updated the code based upon sugestions from 
python-dev and others.

please view my origanal patch here:

This patch adds one method - createMockInstance
(classDef, overrides, *initArgs, **initKwds)
to unittest.TestCase, and two classes MockFactory and 
MockMethod.

Since both these classes should never really be used 
outside the scope of a unittest, I thought it best to add 
them to the unittest module (allthough it is getting rather 
big - should be split into a package?)
