How do I get Flake8 to work with F811 errors?

Question

We're using flake8 to test our code, and we're using pytest with fixtures. The following code:

from staylists.tests.fixtures import fixture1  # noqa: F401

def test_case(fixture1):  # noqa: F811
    # Test goes here
    assert 1 == 1

Generates a lib/python/test.py:3:1: F811 redefinition of unused 'fixture1' from line 1 error during linting.

• Why does it ignore the noqa flag?
• Is there a better way to avoid flagging this error?

Answer 1

The F401 and F811 errors can be avoided by moving all fixtures into the conftest.py file. Pytest loads this file automatically and makes all fixtures inside available in all tests, even without explicit import statements.
