Angular RouteLink测试角度2

我正在测试使用RouteLink指令的组件，如下所示：

let comp: AppComponent;
let fixture: ComponentFixture<AppComponent>;
let el: DebugElement;
let injector: Injector;
let languageService: TranslateService;
let location: Location;
let backend: MockBackend;
let connection: MockConnection; // this will be set when a new connection is  emitted from the backend.

let mockRouter: any;
let mockActivatedRoute: any;
const mockBackendResponse = (connection: MockConnection, response: string) => {
  connection.mockRespond(new Response(new ResponseOptions({ body: response })));
};
describe('testComponent', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      declarations: [AppComponent],
      imports: [HttpModule, RouterTestingModule, TranslateModule.forRoot({
        provide: TranslateLoader,
        useFactory: (http: Http) => new TranslateStaticLoader(http, './assets/language', '.json'),
        deps: [Http]
      })],
      providers: [
        { provide: LanguageService, useClass: LanguageService },
        { provide: BackendLocatorService, useClass: BackendLocatorService },
        { provide: XHRBackend, useClass: MockBackend },
        { provide: APP_BASE_HREF, useValue: '/' }
      ]
    });

    injector = getTestBed();
    backend = injector.get(XHRBackend);
    languageService = injector.get(TranslateService);
    location = injector.get(Location);

    backend.connections.subscribe((c: MockConnection) => connection = c);
    fixture = TestBed.createComponent(AppComponent);
    comp = fixture.componentInstance; // BannerComponent test instance
    // get title DebugElement by element name
  });
  it('is defined', () => {
    expect(TranslateService).toBeDefined();
    expect(languageService).toBeDefined();
    expect(languageService instanceof TranslateService).toBeTruthy();
  });

  it('ROUTLINK CLICK', () => {
    fixture.detectChanges();
    let links = fixture.nativeElement.querySelectorAll('a');
    links[1].click();
    console.log(links[0]);
    expect(location.path()).toBe('/home');
  });
});

有什么想法吗？

所以您当前有一个错误，在修复该错误后，您将得到另一个错误

当前错误

应为'/home'

，因为锚点上的

单击（）

涉及异步事件处理。但是您的期望是同步的，并且发生在

单击（）之后，异步操作完成之前

要解决此问题，您可以使测试
异步
，然后在
单击（）
之后，您可以通过调用
fixture.whenStable（）

一旦你解决了这个问题，你就会遇到另一个问题。目前您没有为
路由测试模块
配置路由。通过调用
RouterTestingModule.withRoutes（Routes）
进行设置。您可以使用真实的应用程序路由，或者如果需要，设置一些用于测试的假路由

 Chrome 53.0.2785 (Windows 7 0.0.0) testComponent ROUTLINK CLICK FAILED
 Expected '' to be '/home'.

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

                  // use async
it('ROUTLINK CLICK', async(() => {
  fixture.detectChanges();
  let links = fixture.nativeElement.querySelectorAll('a');
  links[1].click();
  fixture.whenStable().then(() => {
    expect(location.path()).toBe('/home');
  });
}));
