Mocking Components with Angular 2

I am trying to mock the Heroes-Component of the 'Tour of Heroes' Angular 2 Tutorial. But I don't know how to mock the router, which is needed for instantiating the HeroesComponent. I tried to create a Spy with Jasmine, but that doesn't work, because it is missing the property 'RootComponentType'.

How can I make this work?

import {HeroesComponent} from "./heroes.component";
import {Router} from "@angular/router-deprecated";
import {HeroService} from "./hero.service";


describe('HeroesComponent', () => {
    let heroes:HeroesComponent;
    let router:Router;
    let service:HeroService;
    beforeEach(() => {
        router = jasmine.createSpyObj('Router', ['navigate']);
        service = new HeroService(/* I will care about this later */);
        heroes = new HeroesComponent(router, service);
    });
    it('should be defined', () => {
        expect(heroes).toBeDefined();
    });
});
