Overriding mark for a single test in PyTest

Question

There is a test file with a global marker for each stored test:

from pytest import mark

pytestmark = mark.unit

This works as expected and all of the tests from this file as marked as unit. However, I'd like to override the mark for a single test, so that it no longer has the unit marker.

When I use the decorator on the test function that I want to modify, instead of overriding the original marker, it contains both unit and the new integration markers:

@mark.integration
def test_integration():
    pass

I've checked the marker decorator sources and it seems that it calls store_mark and has no additional properties that would let me override existing test markers.

Are there any idiomatic solutions to override existing testing marks or should I just store the tests in a separate file?

Answer 1

I don’t think there is built-in functionality for this. You have a few options:

Implement a plugin that gives you an unmark decorator. Someone has already tried this but I haven’t tested it.

Or Put all of your unit tests in a class and decorate the class with the marker.

import pytest

@pytest.mark.unit
class TestUnits:
    def test1(self):
        pass

@pytest.mark.integration
def integration_test():
    pass
