I created a few test cases and they all passed... That\'s because they are not being run.
From Xcode, I get:
Test Suite \'All tests\' started at... Test Suite
If you are creating a new test target in Xcode 5+ and planning to use SenTestKit for unit tests, changing the 'Wrapper Extension' build setting of your test target to 'octest' from the default 'xctest' will help execute the test cases.
