I’ve started looking into development on iPhone and was a little surprised that unit testing was challenging. I found this project by Google that seems promising:
iPhoneUnitTesting – google-toolbox-for-mac – Google Code – How to do iPhone unit testing.

I’m going through Bill Dudney’s book from the Prags, which seems very good. You get up and running quickly, though it isn’t (and doesn’t claim to be) an in-depth resource on Objective C. I also got Daniel Steinberg’s Cocoa Programming book, which is a great quick start and good companion to the iPhone book.

Now I just need an iPhone…
