 // Cocoa controller unit tests. It does several key things:
 //   - Creates and displays an empty Cocoa window for views to live in
 //   - Loads the appropriate bundle so nib loading works. When loading the
 //     nib in the class being tested, your must use |mac_util::MainAppBundle()|
 //     as the bundle. If you do not specify a bundle, your test will likely
 //     fail.
 // It currently does not create an autorelease pool, though that can easily be
 // added. If your test wants one, it can derive from PlatformTest instead of
 // testing::Test.
