我正在开发一个github存储库(带有角度4和angular-cli),我有一些测试,Karma和Jasmine在master分支中工作.

现在我正在尝试添加延迟加载功能,我已经创建了一个新的分支,你可以在这里看到.

问题是,之前的测试,现在他们没有.这很有趣,因为只有延迟加载模块的测试失败了......

这是代码和错误:

import {async, TestBed} from '@angular/core/testing';
import {APP_BASE_HREF} from '@angular/common';
import {AppModule} from '../../app.module';
import {HeroDetailComponent} from './hero-detail.component';

describe('HeroDetailComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [AppModule
      ],
      providers: [
        {provide: APP_BASE_HREF, useValue: '/'}
      ],
    }).compileComponents();
  }));

  it('should create hero detail component', (() => {
    const fixture = TestBed.createComponent(HeroDetailComponent);
    const component = fixture.debugElement.componentInstance;
    expect(component).toBeTruthy();
  }));
});

错误是这样的:

Chrome 58.0.3029 (Mac OS X 10.12.6) HeroDetailComponent should create hero detail component FAILED
