我正在使用我的Angular应用程序进行单元测试,
我的路由在特定模块中被删除,该模块是在app.module.ts下导入的,
这是我的路由模块：
APP-routing.module.ts
import { NgModule } from '@angular/core';
import { RouterModule,Routes } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { WelcomeComponent } from './welcome/welcome.component';
import { CustomersListComponent } from './customer/customers-list/customers-list.component';
import { CustomerDetailComponent } from './customer/customer-detail/customer-detail.component';
import { ApplicationParametersComponent } from './superAdministrator/application-parameters/application-parameters.component';
import { InscriptionComponent } from './inscription/inscription.component';
const routes: Routes = [
{ path: '',redirectTo: '/login',pathMatch: 'full' },{ path: 'login',component: LoginComponent },{ path: 'login/:keyWording',{ path: 'welcome',component: WelcomeComponent },{ path: 'customers-list',component: CustomersListComponent },{ path: 'customer-create',component: CustomerDetailComponent },{ path: 'customer-detail/:idCustomer',{ path: 'application-parameters',component: ApplicationParametersComponent },{ path: 'inscription',component: InscriptionComponent }
];
@NgModule({
imports: [ RouterModule.forRoot(routes) ],exports: [ RouterModule ]
})
export class AppRoutingModule {}@H_502_18@
这是我的app.module.ts(用于导入路由模块的地方：
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { SharedModule } from './../shared/shared.module';
import { LoginComponent } from './login/login.component';
import { WelcomeComponent } from './welcome/welcome.component';
import { AppComponent } from './app.component';
import { CustomerModule } from './customer/customer.module';
import { ApplicationParametersComponent } from './superAdministrator/application-parameters/application-parameters.component';
import { InscriptionComponent } from './inscription/inscription.component';
import { DxProgressBarModule } from 'devextreme-angular';
@NgModule({
declarations: [
AppComponent,LoginComponent,WelcomeComponent,ApplicationParametersComponent,InscriptionComponent
],imports: [
AppRoutingModule,/* HERE IS THE ROUTING FILE */
SharedModule,CustomerModule,DxProgressBarModule/*,BrowserAnimationsModule,BrowserModule*/
],providers: [],bootstrap: [AppComponent]
})
export class AppModule { }@H_502_18@
在我的测试文件下,我关注了此博客中的tuto：
https://codecraft.tv/courses/angular/unit-testing/routing/
我的路由测试测试文件如下：
import { async,ComponentFixture,TestBed } from '@angular/core/testing';
import { AppComponent } from './app.component';
// DevExtreme Module
import {DxProgressBarModule,DxTemplateModule} from 'devextreme-angular';
// Router Modules
import {RouterTestingModule} from '@angular/router/testing';
// Services and HTTP Module
import { SessionService } from './../shared/service';
import { HttpService } from './../shared/service';
import {HttpModule} from '@angular/http';
// Routs testing
import {Router,RouterModule} from '@angular/router';
import {fakeAsync,tick} from '@angular/core/testing';
import {Location} from '@angular/common';
import {LoginComponent} from './login/login.component';
import {WelcomeComponent} from './welcome/welcome.component';
import {ApplicationParametersComponent} from './superAdministrator/application-parameters/application-parameters.component';
import {InscriptionComponent} from './inscription/inscription.component';
import {CUSTOM_ELEMENTS_SCHEMA} from '@angular/core';
import {FormsModule} from '@angular/forms';
describe('Testing the application routes',() => {
let location: Location;
let router: Router;
let fixture;
beforeEach(() => {
TestBed.configureTestingModule({
imports: [RouterTestingModule,FormsModule,DxTemplateModule,HttpModule ],providers: [SessionService,HttpService ],declarations: [
AppComponent,InscriptionComponent
],schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
});
router = TestBed.get(Router);
location = TestBed.get(Location);
fixture = TestBed.createComponent(AppComponent);
router.initialNavigation();
});
it('navigate to "inscription" takes you to /inscription',fakeAsync(() => {
router.navigate(['inscription']);
tick();
expect(location.path()).toBe('/inscription');
}));
});@H_502_18@
我的测试失败,表明：
Expected '' to be '/inscription'.

想法？
解决方法
您忘记将路由导入到测试文件中的RouterTestingModule.
您必须将export关键字添加到AppRoutingModule文件中的const路由,然后您可以在测试文件中导入路径(并将它们添加到您的测试配置中).
import {routes} from '...'; // I don't have the app-routing.module file path.
...
...
...
beforeEach(() => {
TestBed.configureTestingModule({
imports: [RouterTestingModule.withRoutes(routes),<-- I added the routes here.
FormsModule,HttpModule
],schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
});
router = TestBed.get(Router);
location = TestBed.get(Location);
fixture = TestBed.createComponent(AppComponent);
router.initialNavigation();
});@H_502_18@
如果您没有在路由器测试模块中加载路由,则导航时将无法知道去哪里,因此它将返回原始页面并在控制台中出错.
您所遵循的教程有一种非常奇怪的方法来处理路由,因为tick()用于fakeAsync测试,这是一个真正的异步测试.所以你必须使用Promise< boolean>由router.navigate返回：
it('navigate to "inscription" takes you to /inscription',() => {
router.navigate(['inscription']).then(() => {
expect(location.path()).toBe('/inscription');
});
});@H_502_18@
