Generating multiple suites with different configurations

[WisdomPill]

I was looking for a way to launch all tests multiple times with different DJANGO_SETTINGS_MODULE is that possible?

specifically running all of these tests,
if I am able to generate multiple tests were I can configure django on a function basis then it would be easier for me to parallelise it.
I tried using pytest_configure and it works for setting up django, but I would like to setup a different DJANGO_SETTINGS_MODULE and configure django for each different settings I have. At the moment the following works.

from os import environ
from django import setup

def pytest_configure():
    environ["DJANGO_SETTINGS_MODULE"] = "settings.sqlite"
    setup()

So I started digging and trying out pytest_generate_tests since it looked like I could parametrize tests but I don't want to add the parameter to all of them,
would be nice to use a fixture on function scope with autouse and configure it from there.
So I tried it like the following but it looks like it is not used.

@pytest.fixture(autouse=True, scope="function")
def django(settings_module) -> None:
    environ["DJANGO_SETTINGS_MODULE"] = settings_module
    setup()

def pytest_generate_tests(metafunc):
    settings_modules = [
        "settings.sqlite",
        "settings.sqlite_gzip"
    ]
    metafunc.parametrize("settings_module", settings_modules)

I am thinking it is not called early enough.

Could you help me understand how to implement it such solution if it's possible at all?

Can an automatically running and parameterized fixture help you?

@pytest.fixture(autouse=True, scope="function", params=["settings.sqlite", "settings.sqlite_herd"])
def django(request) -> None:
    environ["DJANGO_SETTINGS_MODULE"] = request.param
    setup()
