GitHub Actions No Windows Test Output

[jgehrig]

The Windows test runs do not display any test output, even when -VV or --output-on-failure arguments are used.

When ctest is run manually inside of the runner via, output is displayed. https://github.com/nelsonjchen/reverse-rdp-windows-github-actions

When tst_* and test_* executables are uploaded as artifacts and run locally, test output is displayed.

Bug in GitHub Actions?

Here is an example of this issue...

Actions + Windows lacks ctest failure output: https://github.com/equalsraf/neovim-qt/pull/885/checks?check_run_id=3094273084

AppVeyor + Windows correctly displays ctest output: https://ci.appveyor.com/project/equalsraf/neovim-qt/builds/40031037/job/ddhiyj6vtqyaclt9

The test binaries built by GitHub actions work correctly. You can download the exe, run it locally and observe the correct test output.

When ctest is run manually on the runner (via RDP), you can observe the correct output.

It looks like the GitHub Actions runner is not correctly piping output.

I dont think it is a bug, I suspect they are not running at all. Here are two example from a recent PR

1. in linux it looks ok https://github.com/equalsraf/neovim-qt/runs/5035009356?check_suite_focus=true
2. in windows it is empty and the execution time is 0 - https://github.com/equalsraf/neovim-qt/runs/5035011280?check_suite_focus=true

Maybe a consequence of this check

      - name: Test
        if: ${{ !startsWith(matrix.runner, 'windows') }}

This was added intentionally to prevent this issue from causing build failures on GitHub Actions.

Although it looks like you discovered this in your PR already. Comment added for reference.
