New submission from Sam Park <[email protected]>:
The expectation is that the __module__ attribute for a patched function should
persist after patching.
Minimal test case is attached. Simply run pytest in a venv with the files.
Output:
def test_zxc():
with mock.patch.object(mymodule, 'asd', side_effect=mymodule.asd,
autospec=True) as spy_asd:
> assert spy_asd.__module__ == 'mymodule'
E AssertionError: assert None == 'mymodule'
E + where None = <function asd at 0x7fe4cd6fd620>.__module__
test_mymodule.py:8: AssertionError
Originally reported at https://github.com/pytest-dev/pytest-mock/issues/146
before it was determined this was a unittest.mock issue.
Happens on both Python 2.7 and 3.7. Probably not really tied to a specific
Python version and more of mock library issue.
My local venv:
Python 3.7.2
pytest 4.4.1
