XCode 5 unit testing: starts my app

Question

When I run my tests in XCode 5, the main window of my OS X app appears on the screen for a couple of seconds while running the tests. Why? Even if I uncomment all my tests i

Answer 1

In XCode 7, removing Host Application does not work for me. Indeed I use the following to avoid app runs.

1. Setup Test Scheme Arguments

2. in main.m

   static bool isRunningTests()
   {
       NSDictionary* environment = [[NSProcessInfo processInfo] environment];
       NSString* testEnabled = environment[@"TEST_ENABLED"];
       return [testEnabled isEqualToString:@"YES"];
   }
   

3. modify main()

   int main(int argc, char * argv[]) {
       @autoreleasepool {
           if (isRunningTests()) {
               return UIApplicationMain(argc, argv, nil, nil);
           } else {
               return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
           }
       }
   }
