>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3524223. --> Reported by: [phenaproxima](https://www.drupal.org/user/205645) Related to !542 >>> <p>Our CI test runs are slower than I'd ideally like, largely because they run serially. If we adopted run-tests.sh, it'd be a lot faster.</p> <p>Unfortunately, this just...doesn't work, at least not natively. You cannot, it seems, point run-tests.sh at a directory and hope it finds the tests. It seems to depend on the tests being autoloadable by Drupal's unique autoloading mechanism.</p>
