I have just upgraded my angular app from Angular 11 to 12 using the steps provided from https://update.angular.io/. I am able to compile and run. However, when I run npm test, I got the following error for all my test:
> npm run env -s && ng test

Thanks in advance if anyone is able to help.
I have managed to troubleshoot and solve the issue. I have also a tsconfig.spec.json, which extends from tsconfig.json. This tsconfig.spec.json overrides the module property from es2020 to commonjs. As such, by removing the override property, my tests are running again. Hope this helps anyone who faced the same issue as me.
