角度单位测试:错误:无法匹配任何路线.网址细分:'主页/顾问'

Question

我正在使用我的角度4.0.0应用程序进行单元测试,我的实际组件中的一些方法是通过以下方式调用手动路由:

method(){
....
    this.navigateTo('/home/advisor');
....
}

使用navigateTo是一个自定义路由方法,调用此方法:

  public navigateTo(url: string) {
    this.oldUrl = this.router.url;
    this.router.navigate([url], { skipLocationChange: true });
  }

我有这个路由文件:

import ...     // Components and dependencies

const homeRoutes: Routes = [
  {
    path: 'home', component: HomeComponent,
    children: [
      {
        path: 'registration',
        component: RegistrationComponent,
        children: [
          {
            path: 'synthese',
            component: SyntheseComponent
          },
          {
            path: 'queue',
            component: QueueComponent,
            children: [
              {
                path: 'queue-modal',
                component: QueueModalComponent
              },
              {
                path: 'confirm',
                component: ConfirmComponent
              }
            ]
          }

          {

          {

            component: ValidCloseComponent
          },
          {
            path: 'application',

          }
        ],
        canActivate: [AuthGuardAdviser]

        component: StockComponent,
        children: [

            path: 'mobile',
            component: MobileComponent
          },
          {
            path: 'stock-level',
            component: StockLevelComponent
          }
        ]
      },
      {

        //           component: AdminComponent,
        canActivate: [AuthGuardAdmin]
      },
      {
        path: 'rb',
        loadChildren: 'app/home/rb/rb.module#RbModule',

        component: ApplicationComponent
      },
    ]
  },

   ];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forChild(homeRoutes)
  ],
  exports: [
    RouterModule
  ],
  declarations: []
})
export class HomeRoutingModule { }

奇怪的是,即使我的应用程序也能很好地完成,但是测试会抛出这个错误:

失败:未捕获(承诺):错误:无法匹配任何路由.URL段:'home/advisor'错误:无法匹配任何路由.网址细分:'主页/顾问'

好像我有一些缺少的配置.

有任何想法吗 ？？

你需要RouterTestingModule.withRoutes这样：

beforeEach(async(() => {
  TestBed.configureTestingModule({
    imports: [
      RouterTestingModule.withRoutes(
        [{path: 'yourpath', component: BlankComponent}]
      )
    ],
    declarations: [
      BlankComponent,
      YourComponentBeingTested
    ]
  })
  .compileComponents()
}))

根据我的评论:

当您想要对路由器进行单元测试时,您必须使用测试模块,而不是实际模块.

从...开始

import { RouterTestingModule } from '@angular/router/testing';

然后,在你的Testbed中

imports: [RouterTestingModule]

现在,您应该能够对组件进行单元测试

编辑

要对您的路由进行间谍,您需要做的是

spyOn(component.router, 'navigate').and.returnValue(true);

你期望看起来像

expect(component.router.navigate).toHaveBeenCalledWith('/home/advisor');
