I am testing functions from different modules that use an imported helper function from helpers.py. I am monkeypatching this helper function in each module function’s test (please see below). I would like to put setup_do_thing() and mock_do_thing() in a conftest.py file to cut down on repetition and remove general_mocks.py, but am unable to do this due to the different import paths supplied to monkeypatch.setattr() in test_module_1.py and test_module_2.py.

Is there a way to put the fixture in a single file and supply to multiple test modules?

app/helper.py:

def do_thing():
    #do_thing

app/module1.py:

from helper import do_thing

def use_do_thing_for_x():
    ...
    do_thing()
    ...

app/module2.py:

from helper import do_thing

def use_do_thing_for_y():
    ...
    do_thing
    ...

tests/general_mocks.py:

def mock_do_thing():
    #do_other_thing

tests/test_module_1.py:

from general_mocks import mock_do_thing

@pytest.fixture
def setup_do_thing(monkeypatch):
    monkey_patch.setattr('app.module1.do_thing', 
                         mock_do_thing)
    
def test_use_do_thing_for_x(setup_do_thing):
    ...

tests/test_module_2.py:

from general_mocks import mock_do_thing

@pytest.fixture
def setup_do_thing(monkeypatch):
    monkey_patch.setattr('app.module2.do_thing', 
                         mock_do_thing)
    
def test_use_do_thing_for_y(setup_do_thing):
    ...
