I know this is a closed PR, but another option is to use GitHub Actions Test Logger, which produces quite nice summaries automatically.

I knows GitHub Actions Test Logger is great software. And it can report errors faster than using .trx files. Because it's implemented as MSBuild logger.

But GitHub Actions Test Logger requires additional Terms of use agreements to use software.

I've concerned about impact on docfx licensing (MIT). So I've taken approach to parsing trx files and report errors.

Another options I've considered are bellows.

• test-reporter
• github-actions-ctrf

I think the terms of use more affect the maintainers as the test logger won't be a shipped dependency (private asset).
