How to import custom pytestmark? (analogy with pytest_plugins)

[vamotest]

Hi!

Please tell me how to import pytestmark with parameterization correctly?

Conditionally, I can have a file:

# tests_helpers/mark/some_mark.py
pytestmark = pytest.mark.parametrize("n,expected", [(1, 2), (3, 4)])

And I will make an import in my test

from tests_helpers.mark.some_mark import pytestmark

Yes, this will work conditionally, but the import will be highlighted in the IDE as unused.

Maybe there is a mechanism for connecting your fixture to conftest?

pytest_plugins = [
    'tests_helpers.pytest_fixtures.unit.commands',
]

Hi,

Importing the mark like you did is the way to go. Most IDEs have a mechanism to make it not consider the import unused, usually by adding a comment to it.

Thank you so much for the answer.
I know about

from tests_helpers.mark.some_mark import pytestmark  # noqa

but I thought there was a more elegant option

Given that you want to reuse it, perhaps you can give it a more descriptive name, say:

parametrize_for_numbers = pytest.mark.parametrize(...)

And then in your module:

from test_helpers.mark.some_marks import parametrize_for_numbers 

pytestmark = parametrize_for_numbers 

This way you avoid the IDE warning and also can have multiple "parametrization marks" for reuse in your test_helpers.
