What is with all these noqa: F811? Can it be fixed please?

[khorshuheng]

That's because we are importing the fixtures from another module, and flake8 doesn't understand pytest fixtures.

One way to fix it would be not to import the fixture and include it directly in test_launchers, though that would mean it's harder for us to reuse the fixture across different test files.

I will research for way on how this can be circumvented without explicitly adding # noqa: F811, but i am not certain if it is possible.
