Previously, every AppKit tests used the same sharedApplication. Due to this implementation, a could not pass because a previous test made failed the current test. For instance, a test could fail because the window of the previous test resigned (just imagine a new window is the key window in the current test), and this resign could raise an error. The error was displayed for the current test thought this test was perfect !
We now instead of using sharedApplication create a new CPApplication per unit-test file in the class method setUp.
This would break key-value binding setups where a CPCollectionView's content property was hooked up to a CPArrayController's content or arrangedObjects property since the CPArrayController maintains the same object and calls setValue:forKey: with the same object the CPCollectionView already has. Therefore we cannot skip calling reloadContent even when the incoming content array is the same one we got before, because most likely the contents have changed out from under us.
