Is Django Testing Tags Supported?

This is a question rather than a real issue. The documentation does not have anything about this and I couldn't find any regarding issue.

One can use tags for Django tests, is this supported?

This seems related https://github.com/pytest-dev/pytest-django/issues/516

@erayerdin you can use @pytest.mark.some_tag_here instead

[tolomea]

It would be nice if pytest-django translated one to the other. There are usecases where it's convenient that pytest is a no code change drop in replacement.

looks like a tiny little collect hook to upgrade it to a mark

https://github.com/django/django/blob/8bcca47e8356521f52f0738d9633befd53007cae/django/test/utils.py#L844-L853

def pytest_collection_modifyitems(items):
    for item in items:
        for tag in getattr(item.obj, "tags", ()):
            item.add_marker(pytest.mark.django_tag(tag))

I was able to get this to work (somewhat) by setting the following in conftest.py based on @graingert 's suggestion:

def pytest_collection_modifyitems(items):
    for item in items:
        for tag in getattr(item.obj, "tags", ()):
            item.add_marker(tag)

However, this only works for @tag applied to functions - it will not work with tags on an entire TestCase class. I suspect this is because pytest markers don't work on an entire class?

we can add the following block of code to pytest_collection_modifyitems to add @tag valued as pytest markers but it raises an error if a tag is not registered in markers. Is it a good way to go? @bluetech do you have any idea?
