You may be interested in answers to this question: Do OCUnit and OCMock work on the iPhone SDK?. Some links for short:
Google toolbox for Mac(GTM) is a superset of OCUnit. It adds more assert macros, and also has a support for UI testing. OCMock is how you can incorporate mock objects into your unit testing environment.
I have just recently created a project and file template for creating static libraries that also has built-in support for unit testing. You can read about it:

And the templates are located at:

The file template gives you an easy way to add a unit test class with all the necessary OCMock and GTM/OCUnit headers.
