角单元测试:错误:无法匹配任何路线.网址段:“家庭/顾问"

问题描述

在我的angular 4.0.0应用程序下进行单元测试时，实际组件中的某些方法是通过:调用手动路由

Am working on unit testing under my angular 4.0.0 app , some method in my real component is calling manual routing via :

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

带有 navigateTo 的自定义路由方法称为:

with navigateTo is a custom routing method calling this :

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

我有此路由文件:

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

      {
        path: 'application',
        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可以正常运行，但是测试会抛出此错误:

Strangely , even my application goes fonctionnally well ,but the test throws this error :

似乎我缺少一些配置.

任何想法

推荐答案

我的评论如下:

要对路由器进行单元测试时，必须使用测试模块，而不是实际的模块.

When you want to unit test your router, you have to use the testing module, not the actual one.

以

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

然后，在您的测试平台上

Then, in your Testbed

imports: [RouterTestingModule]

现在您应该可以对组件进行单元测试了

Now you should be able to unit test your component

编辑

要监视您的路由，您要做的就是

To make a spy on your routing, what you have to do is

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

您希望它看起来像

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