Do you unit test your Objective-C? No, you probably don’t. Do you have automated UI acceptance tests for your UI? Nope. Do you have any kind of continuous integration set up? No, you don’t.
I don’t understand what is wrong with the Objective-C community that it continuously eschews any form of automated testing. It’s a serious, systemic problem.
This is still a serious, systemic problem in the iOS world. It’s the biggest mistake I see new iOS developers make, but it’s not just new developers — it’s most of us, most of the time. When so many respected developers say it’s worth the effort, why are we still not doing it?
Should you be writing unit tests for your app?
