Current behavior

When trying to use createRoutingFactory, I get the issue seen here.

Expected behavior

createRoutingFactory should automatically handle mocking the Router, but it appears that it isn’t. I feel like I’m probably doing something wrong here.

Minimal reproduction of the problem with instructions

For bug reports please provide the STEPS TO REPRODUCE and if possible a MINIMAL DEMO of the problem via https://stackblitz.com or similar (you can use this template as a starting point: https://bit.ly/2zme3bj).

Constructor for component under test (TimeEntryPage):

    constructor(
        private controlNumberService: ControlNumbersService,
        private fb: FormBuilder,
        private modalController: ModalController,
        private route: ActivatedRoute,
        private router: Router,
        private timeout: TimeoutService
    )

where ControlNumberService and TimeoutService are custom services, ModalController is an Ionic service, and FormBuilder, ActivatedRoute, and Router are Angular services.

Component test:

describe(`TimeEntryPage`, () => {
    const controlNumbersService: StubControlNumbersService = new StubControlNumbersService();
    let router: SpyObject<Router>;
    let spectator: Spectator<TimeEntryPage>;

    const createComponent = createRoutingFactory({
        component: TimeEntryPage,
        params: { controlNumber: '23836110' },
        mocks: [ModalController, TimeoutService],
        providers: [
            {
                provide: ControlNumbersService,
                useValue: controlNumbersService
            },
            FormBuilder
        ],
        imports: [IonicModule, ReactiveFormsModule, SharedModule],
        schemas: [CUSTOM_ELEMENTS_SCHEMA]
    });

    afterEach(() => {
        spectator.debugElement.nativeElement.remove();
    });

    beforeEach(() => {
        route.testParams = { controlNumber: '23836110' };

        spectator = createComponent({ detectChanges: false });

        router = spectator.get(Router);
    });

    it(`should instantiate`, () => {
        expect(spectator.component).toBeDefined();
    });
});

What is the motivation / use case for changing the behavior?
