I'm having some problems with my OCUnit test suite, when running application tests (i.e. on the device). Occasionally, I get a tricky error that seems to be thrown from the OCUnit classes. I've been trying to look through the files added to the test suites, but can't get my head around it.
I've followed the Apple documentation and looked at other tutorials when setting up my test targets, resulting in the following targets (and indented dependencies):
LogicTests
MyApp LogicTests
ApplicationTests MyApp
MyAppTesting ApplicationTests
The last (MyAppTesting) is the one I run on the device to start the test suite.
And as mentioned, the tests fail to start sometimes throwing me the following output in the console:

Does anyone know what could be wrong?
Thankful for any help, Kristofer
P.S. I've posted this on the App dev forums, but haven't had any luck with it yet: https://devforums.apple.com/message/333890
Do you have NSZombieEnabled? I had this issue when I had NSZombieEnabled set to YES in my arguments for my unit test launch target. I've tried everything (cleaning/quitting XCode/restting simulator content). The only solution so far was to disable zombie in my unit test launch
