GHUnit
GHUnit is a new unit testing framework for Mac OS X from Gabriel Handford:
I’ve always wondered why XCode doesn’t have a unit testing GUI like other IDEs, or why the SenTesting framework has to be such a pain to setup, with all its RunScript build phases, shell scripts, octest bundle insanity. After using the GTMTestCase for the iPhone (since SenTesting isn’t supported on the iPhone SDK) I decided to try to re-purpose some of the GTM Unit Testing code into a standalone testing framework and GUI that I could use on both my Mac OS X and iPhone projects.
