Answer 1

you can make your promise function to be async

export function testFactory(auth: any, temp: any) {
  return new Promise(async(res, rej) => {
    const inst = new TestService();
    await inst.ngOnInit();
    res(inst);
  });
}

export let testProvider =
{
  provide: TestService,
  useFactory: testFactory,
  deps: []
};
