[SOLVED] Disable autouse fixtures on specific pytest marks

Disable autouse fixtures on specific pytest marks

Is it possible to prevent the execution of "function scoped" fixtures with autouse=True on specific marks only?

I have the following fixture set to autouse so that all outgoing requests are automatically mocked out:

@pytest.fixture(autouse=True)
def no_requests(monkeypatch):
    monkeypatch.setattr("requests.sessions.Session.request", MagicMock())

But I have a mark called endtoend that I use to define a series of tests that are allowed to make external requests for more robust end to end testing. I would like to inject no_requests in all tests (the vast majority), but not in tests like the following:

@pytest.mark.endtoend
def test_api_returns_ok():
    assert make_request().status_code == 200

Is this possible?

Solution

You can also use the request object in your fixture to check the markers used on the test, and don't do anything if a specific marker is set:

import pytest

@pytest.fixture(autouse=True)
def autofixt(request):
    if 'noautofixt' in request.keywords:
        return
    print("patching stuff")

def test1():
    pass

@pytest.mark.noautofixt
def test2():
    pass

Output with -vs:

x.py::test1 patching stuff
PASSED
x.py::test2 PASSED
