AFAIK it's impossible to find out if a test / test suite ran on a certain platform successfully. So I'd recommend adding fake failure at the end of some basic QUIC test and see if you get that failure on MacOS machines.

I'm doing this by inspecting workitems on helix for specific queue, but yeah what you're suggesting will make things easier. Thanks!
