Force a specific test to always run regardless of "-k"

Hi,

I am trying to add a test to my pytest suite that will verify the python version that is used to run the test and fail and stop testing if the version is lower than 3.8. I’d like to get pytest to always run this test, regardless of any “-k” filtering done on the command line.

For reference, this is the actual test:

@pytest.mark.tryfirst
def test_python_version():
    version = sys.version_info
    if version.major < 3:
        logging.error("python2 is not supported")
        pytest.exit("Stopped testing")
    elif version.minor < 8:
        logging.warning("Use python 3.8 or higher for best results")

I’m a bit new to pytest, but I couldn’t find any marker that provides this functionality. Regardless of the specific aforementioned use case, it seems to me to be a pretty useful thing to have implemented, IMHO.

Thanks.

I see thanks.

Feel free to correct me if I am maybe misguided here

I’m not sure about misguided, but I think it should be enough to have this failing the entire test session during pytest_configure, not the responsibility of a single test.

Closing this issue because I think the question has been answered: the consensus is to use a hook or fixure rather than a test for such code.
