I’ve been knee-deep in iOS unit testing for the past few months. Xcode 4 has been a real blessing as well as a curse. Apple did a great job of integrating unit testing into Xcode 4, but so far has failed to provide much in the way of documentation. To make matters worse, things have changed drastically from Xcode 3. In the upcoming days and weeks I will be sharing what I’ve learned about unit testing in the new Xcode 4 environment.
