Jest test suite failed to run AngularJS v1.x is not loaded! after upgrade from angular 7 to 9 about angular-hybrid HOT 6 CLOSED

i have updated the @uirouter/angular-hybrid configuration used. I am able to run the application successfull after migration, but when I run the unit test i am getting the issue then all the tests are failing.
Hi @christopherthielen if you have any idea could you please help me

I think this is an ngUpgrade problem. angular-hybrid calls angular.module when it gets loaded, but angular isn't loaded yet in your tests.

Try this workaround:
angular/angular#16484

Thank you @christopherthielen . I have already using setAngularJSGlobal to register angular in main.ts

import angular from 'angular';
setAngularJSGlobal(angular);

@christopherthielen any other suggestions you can give about this issue.

@gnbabu make sure you load angularjs before anything else. This message is coming from angular/upgrade/static and indicates that angularjs is being used before it has been loaded. angular/upgrade/static is being used by uirouter-hybrid when uirouter-hybrid gets loaded.

That's about all I can gather from your problem description.

Perhaps this article will help explain it better: https://blog.nrwl.io/ngupgrade-in-depth-436a52298a00

Issue got fixed
This issue is coming because of the paths of the services imports. We have imported service directly from the paths like bellow

import{ WorkPermitsService } from '../../work-permits/work-permits.service';

After upgrading to angular 9 imported paths are not resolved when I run the unit tests. So i have exported it in services index.ts and importing from @services (common place for exporting) where ever required. like this i have done for all.

Change :
export { WorkPermitsService } from '../../work-permits/work-permits.service';

Importing in required places
import { WorkPermitsService} from '@services';
