In Xcode 4.2 when you add a new Objective-C test case class to your project and click the Next button, you will see a Test Type menu. This menu has two choices: Application and Logic. The menu determines the unit test Xcode adds in the class’s implementation file. If you choose Application, Xcode adds a test for the application delegate. If you choose Logic, Xcode adds a dummy test that asserts 1 + 1 = 2.
It doesn’t matter what you choose from the Test Type menu. You’ll probably delete the unit test Xcode creates and add your tests. You can add your tests to both test types.
