test_runner: fix wrongfully printed diagnostic warning while `only: false` by pmarchini · Pull Request #54116 · nodejs/node · GitHub

This PR should address #54052 🐍

The issue (a diagnostic warning printed when only is set to false) is caused by runOnlySubtests being set as the negation of this.only on the subtest.
We have added the repro provided by @UziTech to the snapshot tests.

A question arose while checking the logic:

Given:

test('nested tests with run only', {only: true}, common.mustCall(async (t) => {
  ...
  // The test context can be updated to run subtests with the 'only' option.
  await t.runOnly(true);
  await t.test('this subtest is now skipped - 2', common.mustNotCall());
  await t.test('this subtest is run - 3', { only: true }, common.mustCall(async (t) => {
    await t.test('this subtest is run - 4', common.mustCall());
    await t.test('this subtest is run - 5', { only: true }, common.mustCall());
  }));

  // Switch the context back to execute all tests.
  await t.runOnly(false);
  await t.test('this subtest is now run - 6');
  ...
}))

Is it correct that this subtest is run - 4 is being run even though runOnly is set in the parent test?
Should runOnly be propagated to subtests as well, or is it intended only for "sibling" tests?

Additionally, we recognized the runOnlySubtests propagation change, but we may have missed other changes that might result in breaking functionality. All the current tests seem to be passing, so no relevant changes have been found on the tested paths. Do you notice anything else that we might have broken here?

lgtm. Thanks for the quick fix 💯

Can we put these changes in a new test. This fixture is run with a variety of reporters and makes the diff get really noisy. Some of these are already getting quite large and more difficult to debug as new changes are introduced.

Hey @cjihrig, thanks for your super-fast feedback 🚀
I moved the tests to a new file and added it to test-runner-output.mjs.

Hope that's fine!

I have taken a look at the failing tests and I don't think they are related to the content of this PR.
I believe some of them are flaky.

Is there anything I can do?
