Angular 2: Testing components with router

Question

I am writing the simplest component that is using a routeLink:

@Component({
    selector: \'memorySnippet\',
    templateUrl: \'


        
      

Answer 1

You should have a beforeEachProviders method looking like:

import {MockApplicationRef} from '@angular/core/testing';

beforeEachProviders(() => [
  ROUTER_PROVIDERS,
  provide(APP_BASE_HREF, {useValue: '/'}),
  provide(ROUTER_PRIMARY_COMPONENT, {useValue: YourComponent}),
  provide(ApplicationRef, {useClass: MockApplicationRef}
]);

MockApplicationRef is provided by the framework for this kind of tests.
