pytest throws warning (Unknown config option: collect_ignore)

This package is fantastic! Thank you so much for all the hard work on it.

Description

When attempting to run make test, pytest throws a warning. It appears to have trouble with this section in setup.cfg:

[tool:pytest]
collect_ignore = ['setup.py']

Which is curious, because collect_ignore is an environment variable called out in the pytest documentation.

What I Did

Ran a test on my project with: make test

(pydev) ➜  mypackage make test                      
pytest

I meet the same issue!

[genzj]

Here is a workaround. Just remove the collect_ignore from setup.cfg and specify it via cli args instead, e.g. pytest --ignore=setup.py

Same issue here with Python 3.8.6, pytest-6.2.1

Yep, this seems to have been removed from pytest. The setup.cfg template should be adjusted.

Workaround:

Remove the collect_ignore entry.
Add command line options to pytest using addopts:

[tool:pytest]
addopts = --ignore=setup.py
