    mock.assert_called_once() is not a valid method

    mock.assert_called_once() is a no-op that tests nothing. Instead
    mock.assert_called_once_with() should be used (or use
    assertEqual(1, mock_obj.call_count) if you don't want to check
    parameters).

    Borrowed HACKING rule from Davanum Srinivas's nova patch to
    prevent it from appearing again.
