How do you mock ActivatedRoute

A simple way to mock ActivatedRoute is this one:

    TestBed.configureTestingModule({
      declarations: [YourComponenToTest],
      providers: [
        {
          provide: ActivatedRoute,
          useValue: {
            params: Observable.from([{id: 1}]),
          },
        },
      ]
    });

Then in your test it will be available and your function should work with this (at least the ActivatedRoute part)

You can get it with TestBed.get(ActivatedRoute) in your it functions if you want to stock it in a variable.

Don’t forget to import Observable from rxjs/Rx and not from rxjs/Observable
