Please fix the commit message, and update snapshots (NODE_REGENERATE_SNAPSHOTS=1 ./node test/parallel/test-runner-output.mjs)

Hi, I'm getting a zsh: Permission Denied when attempting to update the snapshots.

Hi, I'm getting a zsh: Permission Denied when attempting to update the snapshots.

perhaps you checked out the repo with another user/with sudo? you might need to chown/chmod

Just reworked the commit message and ran the command given after being able to get access. I'm unsure of the purpose of snapshots - it ended up returning errors that were contained in a file I had no touched and I'm unsure of what to do with the statements returned. Any advice would be appreciated, thanks for all the help!

Errors returned from snapshot:
node/test/parallel/test-runner-output.mjs: line 1: import: command not found

Thanks!

Snapshot tests are in place to validate that the output of test runner reporters stays the same across commits.
do you receive these errors when running the same command on the main branch?

Yes, the error persists on the main branch.

Awesome!
Please note the susystem should be test_runner, not lib 🙂

I'm unsure of the purpose of snapshots

As Moshe explained, snapshots are files containing the expected output for a test. We use these to ensure the reporters work as expected as well as other things, and as this PR proposes a change to the dot reporters output, the snapshots require an update.

I'm unsure of what to do with the statements returned

Does rebuilding the Nodejs executable work? (make -j4)
Does running the tests without the NODE_REGENERATE_SNAPSHOTS env var work?

Calling make -j4 returns an error of:
make: *** [config.gypi] Error 1
and calling the tests without the environment variable returns the same errors.

Sorry for all of the issues! I appreciate all of the aid given and hopefully theres an easy solution hidden in plain sight that I'm just missing, I'll keep digging for it.

Calling make -j4 returns an error of:
make: *** [config.gypi] Error 1

Could you try pasting the entire output, or the error throughout the process?
It is kind of impossible to know what did not work just based on the exit code 🙂

Fortunately the make -j4 appears to have fixed the issue and the
NODE_REGENERATE_SNAPSHOTS=1 ./node test/parallel/test-runner-output.mjs now returns:
ℹ tests 42 ℹ suites 1 ℹ pass 42 ℹ fail 0 ℹ cancelled 0 ℹ skipped 0 ℹ todo 0 ℹ duration_ms 1411.179291

Does this mean that the code is able to be submitted? There are still a few checks that appear to be failing within the pull request.

you should commit all changed snapshot files that are changed by NODE_REGENERATE_SNAPSHOTS=1 ./node test/parallel/test-runner-output.mjs

Hey @Aidan7757 are you still interested in implementing this?

Closing in favor of #53450, which implements a similar change, and has (an) approval(s).
