I applied another workaround of https://github.com/rubygems/rubygems/pull/6739 and run RubyGems/Bundler with Windows platform. turbo_tests is still not working.

Thanks for raising this issue!

From what I remember, an extra FIFO was needed to catch errors outside of examples: https://github.com/serpapi/turbo_tests/pull/10.

If it'll work with stdout instead of tmp/test-pipes, let's do this.

[ilyazub]

ruby/mspec doesn't use FIFO too (ref: https://github.com/ruby/mspec/blob/b23f052a8d262ebd442e60e23d468ed82852f3d8/lib/mspec/runner/parallel.rb#L76-L97)

I'll explore that.

Interesting!

Our approach in RubyGems seem to be working just fine on Windows. Feel free to cherry-pick that if preferred.

Can be closed now! :tada:
