You're not testing your exception handler here, you're testing whether
GWT will call the registered exception handler. This kind of test
should be in GWT itself; you shouldn't test in your own code whether
GWT functions the way it's supposed to.
To test your handler, you should instantiate it and directly call
onUncaughtException to see if it behaves the way you want. What's left
is to ensure your handler is correctly registered as the uncaught
exception handler; but I wonder if this is something to test in a
GWTTestCase... (FYI GWTTestCase *controls* the uncaught exception
handler)
