I have a complex enough application with some tests which as far as I remember used to run and give output whether they were successful or not. I did not run the tests every time I changed the code (not very proud of it) but now after some months after the last test run, I cannot seem to run the tests on device. Xcode has been updated at least 2 times since then. Before giving you the 3 different errors I get each time I run the tests (yes, it is that bad), I have to mention that I get nearly the same behavior with a fresh, minimal test app I created to see what is going on. The tests I run in that case are also minimal, like: assetEqualsObjects(@"a", @"b"); Every time I run the test, I get no output apart from the "success" or "failed" icon, which is not consistent at all, as it passes or fail the same test depending on its whims. "sometimes" i get this popup error: The run destination .... is not valid for Testing the scheme 'TestApplication'. "some other times" i get the following popup: process launch failed: timed out trying to launch app and finally, sometimes I get an error in the main loop in this line: return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); I would go deeper to my app and see what I m doing wrong, but I luckily created a minimal app and i get the same behavior. i would like that someone if not give a solution, at least try to help to isolate the error...
