No tests found when using fedtest with pnpm

Check this failing CI: https://github.com/dotansimha/graphql-yoga/actions/runs/4512947657/jobs/7947092913?pr=2525#step:10:917.

Same error occurs locally:

Run with `--passWithNoTests` to exit with code 0

Repro steps:

1. git clone [email protected]:dotansimha/graphql-yoga.git
2. pnpm i
3. pnpm build
4. cd examples/nestjs-apollo-federation-compatibility
5. pnpm build
6. pnpm test (script for running fedtest)

I am out of ideas about what I can try to remedy this issue, honestly I don't even know why it happens.

Any help would be appreciated - thanks!

P.S. I am not using the GH action because there is already one for the graphql-yoga package and running multiple compatibility GH actions crates a race condition on the PR report comment.

Hello 👋 It looks like a weird issue between pnpm and jest. Unsure when I will be able to look into this.

P.S. I am not using the GH action because there is already one for the graphql-yoga package and running multiple compatibility GH actions crates a race condition on the PR report comment.

FYI action will only attempt to comment on the PR if you provide it Github token -> don't specify it it on the other test and it won't be commenting :)

Cheers! The missing GH token helped and now the compat check works as expected, thank you!

We can leave this issue open just for future reference, but since I have got it working - it's not pressing at all.
