What is the best approach for writing unit tests for iPhone / iPad?

Question

I am developing an iPad application. I\'m not sure if I should write unit tests for this application, and if so, how I should go about writing them.

What would you

Answer 1

Ok, there are two questions being raised here:

1. Is unit testing worth it?

Answer: Definitely. I cannot count the times it has saved me hours of pain and suffering.

2. What's the best way to unit test in the iPhone/iPad environment?

Answer: for myself I skipped sen and moved onto GHUnit and OCMock. GHUnit allows in simulator testing and debugging where as sen doesn't. This alone makes it a better proposition for iPhone/iPad development.
