[regression] tox-gh-actions >= 3 breaks tox >= 4

[alonbl]

OVERVIEW

The tox-gh-actions somehow cause dependencies to not be installed when using recent tox.

The following output is available when running the build manually not in github, notice that the pre-commit which is at the dev dependency is not installed.

$ tox
.tox create: xxx/test_project/.tox/.tox
.tox installdeps: tox-gh-actions==3.*, tox >= 3.21.4
ROOT: tox-gh-actions won't override envlist because tox is not running in GitHub Actions

Invocation

• When tox > 4 and tox-gh-actions==3.* fails.
• When tox > 4 and tox-gh-action==2.* succeeds.
• when tox==3.* and tox-gh-actions==2.* success.

Please play with the dependencies at tox.ini:

requires =
#    tox==3.*
#    tox-gh-actions==2.*
    tox-gh-actions==3.*

SUSPECTED CAUSE

The tox-gh-actions causes requirements of environment to be skipped when tox >= 4

EXPECTED BEHAVIOR

• tox-gh-actions should not affect build environment when running out of github
• tox-gh-actions should not fail with recent tox

Hello @alonbl, thanks for filing an issue. Let me share the result of my initial investigation.

I tried to reproduce the issue on my machine using the given example and I found that we get the same error even when tox-gh-actions is not installed.

At this point, I feel this is not an issue with tox-gh-actions. This may be rather an issue with tox 3 -> 4 upgrade or your tox configuration is not compatible with tox v4.

[alonbl]

Oh, I am sorry, I just removed and added the tox-gh-actions and saw the change, but in reality it does not pull the tox>=4 if I do add the tox-gh-actions, I am sorry.

@alonbl, no worries at all!
