[tor-dev] stem mock_method usage

I am attempting to write a test using test.mocking.mock_method, but I do
not understand how to use it correctly.  Could you give me pointers on the
following smallest (non-)working test case.

import stem
from stem.control import Controller
import test.mocking as mocking

socket = stem.socket.ControlSocket()
controller = Controller(socket)

mocking.mock_method(Controller, 'get_version',


The above code fails with:

Traceback (most recent call last):
  File "mock_method-test.py", line 8, in <module>
    mocking.mock_method(Controller, 'get_version',
  File "stem.dev/test/mocking.py", line 317, in mock_method
    target_class.__dict__[method_name] = mock_wrapper
TypeError: 'dictproxy' object does not support item assignment
