A test case created by the engineers at Facebook for testing UI code. FBSnapshotTestCase takes a configured UIView or CALayer and uses the renderInContext: method to get an image snapshot of its contents. It compares this snapshot to a reference image stored in your source code repository and fails the test if the two images don’t match. A descriptive error message is printed to the console on failure along with a one-line command to see an image diff if you have Kaleidoscope installed.
