====Using the Test Harness====

'''Note: This harness assumes that your test runs properly as a stand-alone application and is not being used as one of the test amongst others.'''

The problem with the test timing out is due to the fact that the Mochitest iframe does not allow fullscreen from the html code inside the frame.
