It's a somewhat misleading traceback. The root issue is that a real error is being raised by a client method you forgot to stub out somewhere in your tests. Make sure that all client API calls are stubbed. When in doubt, stub out more methods but don't add any expected calls for them and see which one raises an "Unexpected Method Call" error on you.

Subject: [openstack-dev] [horizon] test error when using horizon exception handler

While using the horizon exception handler in tabs.py, it works fine in actual execution but triggers the following error in unit test.  I wonder if someone knows what I have missed to do in setting up the test to cause this.

Thanks!
