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';
