Works with setup.cfg?

[Holt59]

I am trying to get this to work for one of my project where I am using setup.cfg for tox configuration instead of tox.ini.

My tox configuration looks like this:

[tox]
envlist = py35, py36, py37, py36-lint

[gh-actions]
python =
    3.5: py35
    3.6: py36, py36-lint
    3.7: py37

[testenv]
deps =
    pytest
commands =
    pytest tests

[testenv:py36-lint]
deps =
    black
    flake8
    flake8-black
    mypy
commands =
    black --check --diff setup.py minilp tests
    flake8 minilp tests
    mypy minilp tests

I have copy/pasted your workflow (simply removed python 3.5), but only the py36-lint environment is tested by tox, as if I ran tox without your tox-gh-actions...

Any workaround?

My project is at https://github.com/Holt59/minilp/tree/packaging.

@Holt59 thanks for reporting the issue. It seems there's a misconfiguration in your setup.cfg.

Here's what I find out. I cloned your repository, checked out packaging branch and run tox command locally. Only py36-lint env was executed. Also, tox -l (show a list of testing) failed.

I checked the tox's documentation and found

Note that setup.cfg requires the content to be under the tox:tox section. pyproject.toml on the other hand is in TOML format.

I made the following change and it seems to have fixed the problem.

@ymyzk Thanks for the information. After updating my setup.cfg, everything works as expected!
