在注入Router Angular 2 Test之前，至少引导一个组件

Question

我正在尝试运行单元测试，该测试使用注入的路由器测试组件。这是我的设置代码...

TestBed.configureTestingModule({
      declarations: [PeopleComponent, PersonComponent],
      providers: [
        {
          provide: Http, useFactory: (backend, options) => {
          return new Http(backend, options);
        },
          deps: [MockBackend, BaseRequestOptions]
        },
        MockBackend,
        BaseRequestOptions,
        PeopleRepository,
        PeopleViewModelLoader,
        PersonViewModelLoader,
        {provide: APP_BASE_HREF, useValue: '/'}
      ],
      imports:      [BrowserModule,HttpModule, RouterModule.forRoot([
        { path: '', component: PeopleComponent },
        { path: 'person/:id', component: PersonComponent }
      ])]
    });

但是我最终得到以下错误......

inline template:0:0 caused by: Bootstrap at least one component before injecting Router.

如何在注入APP_BASE_HREF之前引导组件？如果我没有其他组件，例如我的应用程序中只有一个组件，那么它没有任何意义吗？
