Angular2 Unit Test With Router

Using 2.0.0-rc.4 at the moment, trying to unit test a component that contains the router. The way I used to handle the router doesn't seem to work anymore and I'm getting some strange errors when I try to run my tests. Has anyone managed to get the router injected unit tests working in rc.4 or should I wait until I have fully upgraded my app to rc.5 and fix it then?

My Code:

describe('Component', () => {
    let activatedRoute: ActivatedRoute;
    let component: Component;
    let router: Router;

    beforeEach(() => {
        addProviders(() => [
            Component,
            provide(Router, { useValue: jasmine.createSpyObj('Router', ['navigate'] })
        ]);
    });

    beforeEach(inject([ Component, Router, ActivatedRoute ], (_component, _router, _activatedRoute) => {
        component = _component;
        router = _router;
        activatedRoute = _activatedRoute;
    });

    describe('On Initialisation', () => {

        it('should return true (dummy test)', () => {
            expect(true).toBe(true);
        });

    });
});

When I run this test, it gives me the following error in my powershell:
