Angular CLI 15.1.4 breaks ng test with jsdom because CLI is loading JavaScript bundles as module

Reproduisez le problème du dépôt lié avec npm run test:chrome et npm run test:jsdom, puis examinez la commande test d’Angular CLI et le chargement de son bundle JavaScript. Le travail est considéré comme terminé lorsque les tests jsdom s’exécutent sans le patch tandis que les tests Chrome continuent de réussir, avec un moyen d’ajouter ou d’omettre type="module".

Command

test

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

15.1.3

Description

I have a standard Angular project, using Karma & Jasmine for unit tests. The unit tests run can run in either Chrome or jsdom. I need jsdom because my CI environment doesn't have Chrome (org policy: no browsers on servers).

Angular CLI 15.1.4 introduced a change in https://github.com/angular/angular-cli/pull/24620 wherein Javascript bundles are loaded as modules.

Unfortunately, jsdom doesn't support <script type="module">; it simply doesn't load the module scripts. This is a known issue in jsdom - https://github.com/jsdom/jsdom/issues/2475

Ideally jsdom would add module support; but since that ticket has been open for four years, I'm not holding out much hope. So instead, here's my request:

REQUEST: Could Angular CLI add a flag to add/omit type="module" ?

My workaround for now is patching jsdom (using patch-package) to ignore the type attribute on <script type="module">.

Minimal Reproduction

Clone my git repo: https://github.com/andrewpmontgomery/angular-15-jsdom

1. Run npm install
2. Run npm run test:chrome and all three tests should pass.
3. Run npm run test:jsdom and it should time-out.
4. Run npm run patch-package
5. Run npm run test:jsdom again and now it works.
