Question

I m new to angular 4 and trying to test one of the angular 4 feature router.paramMap from unit tests, Reading route params in fallowing way and working as expected in my applica

Answer 1

I am using a slightly different method of getting the params in my component:

this.id = this.route.snapshot.paramMap.get('id');

And this is what worked for me in the jasmine test:

{
      provide: ActivatedRoute,
      useValue: {
        snapshot: {
          paramMap: convertToParamMap({id: 1})
        }
      }
}
