Xcode - Debugging a unit test target

Question

I am writing tests for my iPhone app using OCUnit. Is there any way to debug the unit tests and have a break point to see what the heck is happening?

It's ridiculously hard to write unit tests without being able to use breakpoints.

Answer 1

Using XCode 4.2, (with SenTestKit unit tests as set up by checking the "Include Unit Tests" checkbox when setting up the project), Product->Test wasn't hitting my breakpoints, but Product->Perform Action->Test Without Building seems to do the trick. Hope this helps.

Answer 2

The link posted by David Gelhar is correct for Xcode 3.

For Xcode 4, things are much simpler. Edit your current scheme and go to the "Test" action. Click the '+' at the bottom and add the test bundle that contains the tests you want to run. Now when you choose Product -> Test, it will run those tests. Any active breakpoints will be hit just like you'd expect.

Answer 3

Here's a blog post: Debugging Cocoa application unit tests with instructions for how to do this (for XCode 3 at least; not sure about XCode 4).
