Two to look at:

http://code.google.com/p/pymox/  - this is what we use all over the
place at Google. It is supposedly similar to Java's EasyMock.


This one is interesting because it doesn't have the somewhat odd out
of order catch-all "now check that everything I predeclared would
happen has happened" method as pymox does.  It records things and you
write normal unittest assertions based on inspecting the mocks after
being used.

I'm really not sure what the state of the art is at the moment because
once a large project starts using a mock library of any sort, it tends
to become committed to using it and doesn't change as that'd make
tests less consistent.
