Suppressed Pylint Warnings

unused-argument

FP when a fixture is used in an applicable function but not referenced in the function body, e.g.

def test_something(conftest_fixture):  # <- Unused argument 'conftest_fixture'
    assert True

unused-import

FP when an imported fixture is used in an applicable function, e.g.

from fixture_collections import imported_fixture  # <- Unused imported_fixture imported from fixture_collections

def test_something(imported_fixture):
    ...

redefined-outer-name

FP when an imported/declared fixture is used in an applicable function, e.g.

from fixture_collections import imported_fixture

def test_something(imported_fixture):  # <- Redefining name 'imported_fixture' from outer scope (line 1)
    ...

no-member

FP when class attributes are defined in setup fixtures

import pytest

class TestClass(object):
    @staticmethod
    @pytest.fixture(scope='class', autouse=True)
    def setup_class(request):
        cls = request.cls
        cls.defined_in_setup_class = True

    def test_foo(self):
        assert self.defined_in_setup_class  # <- Instance of 'TestClass' has no 'defined_in_setup_class' member
