Mocking router.events.subscribe() Angular2

Question

In my app.component.ts I have the following ngOnInit function:

ngOnInit() {
    this.sub = this.router.events.subscribe(e => {
      if (e instanceof Navi

This is a really old question but I just came across it looking for something better than what i have and in my case i need to test several different events. My basic approach was just to change the Router.events to a non read only value like

 (router as any).events = new BehaviorSubject(null);
 fixture.detectChanges();
 router.events.next(new NavigationEnd(0, 'http://localhost:4200/login', 
 'http://localhost:4200/login'));
  expect(comp.loggedIn).toEqual(true);

Hope maybe that helps someone. I couldn't find an easier solution after looking around
