Improve Support For Matrix Testing

[fkirc]

attranslate uses "matrix-testing" to test Ubuntu, macOS and Windows: https://github.com/fkirc/attranslate
However, supporting "matrix-testing" with skip-duplicate-actions seems to be cumbersome.
The screenshot below illustrates the problem.
The workflow is here: https://github.com/fkirc/attranslate/blob/master/.github/workflows/ci.yml
One way to fix it are skip-checks for individual workflow-steps.
This is already doable, but it requires one additional line per step.

After changing the "required checks" to only "ci", the PR is mergeable again.
However, this change might yield "normal" PRs unmergeable (PRs where tests were not skipped).

I am running into this issue as well - is there a fix for parallel tests?

[fkirc]

Right now, the only workaround I am aware of is to skip individual steps (described in README).
This should be doable, but it might lead to quite a lot of boilerplate YAML-code.

That is what I did, and now the pre_job is no longer working....

[fkirc]

If you are aiming to skip individual steps, then you might want to delete your pre_job, and instead use a regular step for skip-duplicate-actions.
But anyways, I cannot give detailed advice because there are nearly infinite ways to use skip-duplicate-actions as a pluggable component.
The README only contains two possible configurations.

It's working - thank you so much!!

I was facing this problem as well and was happy to find this issue! Will give the non-pre-job approach a try.
