I'm following this guide about logic unit testing:
https://developer.apple.com/library/ios/#documentation/DeveloperTools/Conceptual/UnitTesting/02-Setting_Up_Unit_Tests_in_a_Project/setting_up.html

Stack trace:
Also, I've tried to create completely new project and repeat procedure, but the problem remains. Application unit testing runs as expected.
