Public bug reported:
By doing this:
tox -e py36 -- nova.tests.unit.test_rpc --until-failure
I'm able to trigger this setup failure:
nova.tests.unit.test_rpc.TestRPC.test_add_extra_exmods

It looks like that's because the notification setup in the base test class
isn't taking into account when the RPCFixture is being used:
https://github.com/openstack/nova/blob/b7a018f1265d9e0354e26822d32cbdc789819c35/nova/test.py#L237
That should probably be nested under the "if self.STUB_RPC:"
conditional.
