javascript - 未找到 Angular 返回路线的 Jasmine 单元测试
问题描述
我最近升级到 Angular 9.1.0-rc.2,一切看起来都正常。我能够在本地和服务器上正常提供应用程序,但是在运行 jasmine 单元测试时,每次测试的随机组件都会出现以下错误:
Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'not-found'
Error: Cannot match any routes. URL Segment: 'not-found'

这是我设置路由的方式: app-routing.module.ts
import { MetaGuard } from '@ngx-meta/core';
import { UserModule } from './modules/user/user.module';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { LoggedInGuard } from 'ngx-auth-firebaseui';
import { AdminGuard } from '@shared/guards/admin.guard';
import { CourseModule } from './modules/course/course.module';
import { AdminModule } from './modules/admin/admin.module';
import { PagesModule } from './pages/pages.module';
const routes: Routes = [
{
path: '',
loadChildren: async (): Promise<PagesModule> =>
import('./pages/pages.module').then((m: { PagesModule: PagesModule }) => m.PagesModule)
},
{
canActivateChild: [MetaGuard],
path: 'admin',
loadChildren: async (): Promise<AdminModule> =>
import('./modules/admin/admin.module').then((m: { AdminModule: AdminModule }) => m.AdminModule),
canActivate: [LoggedInGuard, AdminGuard]
},
{
path: 'course',
loadChildren: async (): Promise<CourseModule> =>
import('./modules/course/course.module').then((m: { CourseModule: CourseModule }) => m.CourseModule),
data: {
title: 'Course'
}
},
{
path: '**',
redirectTo: '/not-found',
data: {
title: 'Page Not Found'
}
}
];
@NgModule({
imports: [
RouterModule.forRoot(routes, {
scrollPositionRestoration: 'enabled'
})
],
exports: [RouterModule]
})
export class AppRoutingModule {}
页面路由.module.ts
import { NotFoundComponent } from './not-found/not-found.component';
import { HomeComponent } from './home/home.component';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
const routes: Routes = [
{
path: '',
component: HomeComponent
},
{
path: 'not-found',
component: NotFoundComponent
}
];
@NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule]
})
export class PagesRoutingModule {}
app.module.ts
@NgModule({
declarations: [AppComponent],
imports: [
CommonModule,
BrowserModule,
BrowserAnimationsModule,
AppRoutingModule,
HttpClientModule,
BrowserAnimationsModule,
MetaModule.forRoot({
provide: MetaLoader,
useFactory: metaFactory
}),
FirebaseModule,
SharedModule,
Angulartics2Module.forRoot({
gst: {
trackingIds: [environment.googleAnalytics]
}
})
],
bootstrap: [AppComponent]
})
在实际调用此路由的组件中:
this.router.navigate(['not-found']);
我尝试过的事情:
- 删除 Route 中的异步调用
- LazyLoad 孩子:
loadChildren: './modules/course/course.module#CourseModule'
- 放
this.router.navigate(['/not-found'])
- 在主 app-routing.module.ts 中直接加载 NotFoundComponent
- 当我注释掉任何使用该路由的组件时,单元测试工作正常。
请注意,当我提供应用程序时,我可以访问未找到的页面。我有点坚持这一点,并会感谢任何可能导致此问题的提示。
解决方案
由于这里的答案,我似乎能够解决这个问题:https ://stackoverflow.com/a/45315961/1432248
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
RouterTestingModule.withRoutes([{ path: 'not-found', component: NotFoundComponent }]),
...,
],
declarations: [..., NotFoundComponent],
}).compileComponents();
}));
编辑您的 RouterTestingModule 并使用withRoutes
并添加缺少的路由的路径和组件。原始答案详细解释了为什么会发生这种情况。
