I used to joke that writing unit tests for iOS development is not necessary since there’s a compiler and laugh real hard. What I realized was that some people thought that it wasn’t a joke. Even worse, when I asked about unit tests during interviews, some candidates didn’t know how to write tests.

The root cause of this, as I see it, is that writing tests aren’t really covered at Apple’s developer documentations. And with all the new boot camps and training courses turning out iOS developers not covering testing at all, testing issue escalates to yet another level.

Here are a list of my recommendations to get started. I will create screencasts on iOS development in the future since I have more time and will ALWAYS show tests along with anything I do. Hope this helps and ping me with any questions, I’ll do my best to help.

Screencasts

Great screencasts by Jon Reid with real world examples

Lynda.com has a course based on Xcode 4, but just about all the stuff still applies.
