`node:test` custom reporters get `test:stdout` and `test:stderr` events before `test:dequeue`

What steps will reproduce the bug?

Create a folder with these files:

index.test.mjs:

import { it } from "node:test";

it("test", () => {
  console.log("message from the test");
});

reporter.mjs:

import util from "node:util";

export default async (source) => {
  for await (const event of source) {
    if (event.type === "test:stdout") {
      console.log(event.type, util.inspect(event.data.message));
    }

    if (event.type === "test:dequeue") {
      console.log(event.type, event.data.name);
    }
  }
};

and run

node --test --test-reporter=./reporter.mjs

which will print

test:dequeue index.test.mjs
test:stdout 'message from the test\n'
test:dequeue test

How often does it reproduce? Is there a required condition?

It always does the same

What is the expected behavior? Why is that the expected behavior?

I expected test:dequeue test to be printed before test:stdout 'message from the test\n' as the documentation states "Emitted when a test is dequeued, right before it is executed."

What do you see instead?

The test:stdout event is emitted before the test:dequeue, which makes it impossible to understand which test was running when the message was written to stdout.

Commencez par exécuter la commande signalée avec index.test.mjs et reporter.mjs afin de reproduire l’ordre des événements. Lisez la gestion de reporter-event de node:test test_runner et ajoutez une couverture pour ce cas ; le travail est terminé lorsque test:dequeue est observable avant test:stdout pour la sortie de ce test, conformément à la sémantique documentée.
