### FOR TESTING PURPOSES | |
# This workflow runs in the context of `main`, and ignores changes to | |
# workflow files in PRs. For testing changes to this workflow from a PR: | |
# - Make sure the PR uses a branch from the base repository (requires write | |
# privileges). It will not work with a branch from a fork (missing secrets). | |
# - Uncomment the `pull_request` event below, commit separately with a `DO | |
# NOT MERGE` message, and push to the PR. As long as the commit is present, | |
# any push to the PR will trigger this workflow. | |
# - Don't forget to remove the `DO NOT MERGE` commit once satisfied. The run | |
# will disappear from the PR checks: please provide a direct link to the | |
# successful workflow run (can be found from Actions tab) in a comment. | |
