Ignoring unrasiseable from offending libraries

[awichmann-mintel]

Hello,
The new unraiseable exception feature in pytest 6.2 is throwing errors for unclosed resources in botocore. Since this is an ongoing issue, my team and I would like to ignore these warnings only from certain libraries.

Our best solution is to filter all ResourceWarnings from _pytest with the warnings module in a fixture like so...

@pytest.fixture(scope="session", autouse=True)
def silence_resource_warnings():
    warnings.filterwarnings(
        action="ignore", message="unclosed", category=ResourceWarning, module="_pytest"
    )

Is this advisable? Is there a way to target the module that is actually not cleaning up these resources?

edit: additionally, if this were possible, do you have any advice on how to test such a fixture silences the correct libraries?

If by "certain libraries" here you mean pytest rather than boto3, then you can ignore it by adding a ignore::pytest.PytestUnraisableExceptionWarning warning filter (pytest has an option for this, you don't need to use a session fixture), or by disabling the plugin by passing the -p no:unraisableexception option to pytest.

If you mean boto3, there is no way to reliably filter ResourceWarnings from a specific module AFAIK.

yeah, that's what I'm going for =/ oh well
