test_runner: ensure test watcher picks up new test files #54225

pmarchini · 2024-08-06T14:55:42Z

This is the initial implementation addressing issue #53077.

I've noticed the issue has been inactive for a while, so I attempted to resolve it by following the provided suggestions.

While this solution seems to work, I'm not entirely satisfied with the implementation.

Thanks for contributing! I've left a few notes and questions.

You'll also need to add a test to https://github.com/nodejs/node/blob/main/test/parallel/test-runner-run-watch.mjs.

Which PR introduced this? Can you ping the original author?

If I'm not mistaken, this change is from @MoLow

I'm not sure what to make of this change 😄

I think it would be great to know if that logic was there for a specific reason. Removing it didn't disrupt any tests.

I added the comment just to ensure that the change didn’t go unnoticed.

Il need to get back from vacation to be in front of a computer to be sure of my answer, but using a single watcher (i.e all mode is probably more efficient and peformant) so creating additional watchers when they are not needed just adds more overhead that is unneeded

I removed the comment in the last commit @cjihrig.
I think we should wait for @MoLow to be back 🚀

I agree with this.

LGTM. It would be good to get @MoLow's review on this though.

will start CI again as soon as this PR lands (just make sure there are no false positive test results) thanks for your patient 🙏

pmarchini · 2024-08-14T16:23:39Z

I've seen that we now have conflicts, gonna fix them ASAP 🚀

cjihrig

This adds a new option to run(), so it needs to have docs.

Great work

pmarchini · 2024-08-29T08:18:00Z

Also, I hope you're still planning to add the cwd option 😄

@cjihrig, if this PR lands, I'll start working on it 😁
Should I open an issue before beginning?
