Can't filter ImportWarning during tests run

I tried setting this config:

[pytest]
filterwarnings =
    ignore::Warning
    ignore::ImportWarning

Running as docker-compose run --rm odoo pytest -s --odoo-database=odoodb my/path/to/test

ignore::Warning ignores all exceptions, except ImportWarning. Not sure why. ignore::ImportWarning does nothing.

I get:

Could it be that ImportWarning is getting thrown in pytest_configure ?

If so, it looks to be related to warnings filter not respected in pytest_configure - https://github.com/pytest-dev/pytest/issues/10128

[oerp-odoo]

As a workaround, to suppress such warnings from Odoo, it is possible to use this kind of option in Odoo config:

log_handler = :INFO,py.warnings:ERROR

Because its a WARNING, if we set higher level, it will be ignored. Currently don’t see cleaner way to workaround it without changing Odoo code…😃

Though, of course it will filter all py.warnings
