test: deflake test-fs-promises-watch-iterator by lpinca · Pull Request #60060 · nodejs/node

lpinca · 2025-09-28T14:19:46Z

Add a delay before writing the files to ensure that the watcher receives the notifications.

lpinca · 2025-09-28T14:23:19Z

test/parallel/test-fs-promises-watch-iterator.js

    for (const fileName of [...this.files]) {
      await writeFile(this.filePath(fileName), Date.now() + fileName.repeat(1e4));
    }
-    await setTimeout(common.platformTimeout(100));


If there was a reason for this I will add it back, but I don't see it.

test/parallel/test-fs-promises-watch-iterator.js

+    // Do the write with a delay to ensure that the OS is ready to notify us.
+    await setTimeout(common.platformTimeout(100));


The same is done in other fs.watch() tests, for example:

node/test/parallel/test-fs-watch-recursive-add-file.js

Lines 41 to 44 in c6316f9

// Do the write with a delay to ensure that the OS is ready to notify us.

setTimeout(() => {

fs.writeFileSync(testFile, 'world');

}, common.platformTimeout(200));

I think this deserves a TODO to investigate why this is occuring and whether or not this is a bug.

There already an open issue (#52601) linked in the commit message.
