where do I check which passing test has failed? I think I have a good idea why it's failing but I dont know which test it is

It looks like all tests pass, though there are two jobs failing in the CI because you didn't run cargo fmt.

Warning: Changes from 'main': PASS -1 / FAIL +1 / ERROR +0 / SKIP +0

I see three failing jobs, and this one says I broke one passing test

You can see the reason in an earlier comment from the bot:

It's a test that unfortunately fails from time to time. It's unrelated to your changes and so you can ignore it :)
