I added a new target as a Cocoa Touch Unit Testing Bundle, named the directory \"MyAppTests\", and the actual framework is not active-- it is highlighted red
XCTest.framework is the bundle that Xcode uses to enable
#import <XCTest/XCTest.h>
To add test cases to an existing project select the target, right click > file > new > objective c test case class. Then in your build phases you can add the XCTest.Framework. Make sure you check the add to target boxes when creating the test case.
