test_runner: fix support watch with run(), add globPatterns option by mcollina · Pull Request #53866 · nodejs/node

mcollina · 2024-07-16T13:19:28Z

This PR fixes one regression I found when using run({ watch: true }): a different test was run after a file rename.

This was caused by calling createTestFileList() from the changed event handler in

Line 423 in 362afa5

const updatedTestFiles = createTestFileList();

.

The problem is that createTestFileList() was loading the glob pattern from argv, which can be whatever. The result was but that was very hard to track.

This PR includes:

tests for run({ watch: true })
a new option called globPatterns that will allow users to control what run() will be globbing
avoid tracking "rename" changes if individual files were specified

+// This is needed, because calling run() with no files will
+// load files matching from cwd, which includes all content of test/
+tmpdir.refresh();
+process.chdir(tmpdir.path);


Won't this break running the test suite in worker threads?

Without this, I would need to fix #53867 as well in this PR.

Let's see if it actually breaks something in CI.

It looks like it did break in the CI (https://ci.nodejs.org/job/node-test-commit-custom-suites-freestyle/37045/). The issue is that the Node test suite is run within a worker thread in the CI. Any test that uses an API that is unsupported in worker threads needs to be skipped there.

I think we still need to remove this.

Ok. I'll need to add a cwd parameter to run(), otherwise it won't work.

I would hold off on adding a cwd parameter for now, but I do foresee us adding it in the future. I'm just not sure if it will break anything until the necessary refactoring happens. Another option is to spawn a child process with the correct cwd.

My guess is because the Python test runner uses it and the process.chdir() call broke that logic.

mcollina · 2024-07-16T15:10:52Z

I guess it's #53867 at play.

cjihrig · 2024-07-16T15:14:04Z

Yep. But also, the Python runner should probably not use a relative path like that.

use primordials?

It looks like this is not addressed.

+    validateArray(globPatterns, 'options.globPatterns');


We should probably validate that the array is not empty. You can add the logic here. Otherwise, I will probably do it in a follow up.

lib/internal/test_runner/runner.js

-  const patterns = hasUserSuppliedPattern ? ArrayPrototypeSlice(process.argv, 1) : [kDefaultPattern];
+  const hasUserSuppliedPattern = patterns != null;
+  if (!patterns || patterns.length === 0) {
+    patterns = [kDefaultPattern];


I would assign the default patterns in the run() validation. You can do that in this PR, otherwise, I will probably do it in a follow up.

Can someone help me with this? I see no conflicts locally but CI does: https://ci.nodejs.org/job/node-test-commit/72259/console.

Was by any chance a force push broke something?
