title: Xcode Test General Pane
body: <p>I am wondering what the “Target” pop-up menu in the General pane for an XCTest bundle does. It lists the other targets in the project, as well as a “None” option. I thought that this pop-up menu is used to select the target being tested so that the tests will automatically be run after every build of that target, but nothing of the sort happens.</p>
  
  <p>Changing the selected menu item has no effect that I can find (including a change to my project file). What does this feature do?</p>
