Angular 4 Error: No provider for ChildrenOutletContexts in Karma-Jasmine Test
Based on the clue provided by @John, I imported RouterTestingModule instead of importing RouterModule and APP_BASE_HREF. So, the following modification in app.component.spec.ts worked!
import { TestBed, async } from '@angular/core/testing';import { FormsModule } from '@angular/forms';import { RouterTestingModule } from '@angular/router/testing';import { AppComponent } from './app.component';import { DashboardComponent } from './modules/dashboard/dashboard.component';describe('AppComponent', () => { beforeEach(async(() => { TestBed.configureTestingModule({ imports: [ RouterTestingModule FormsModule ], declarations: [ AppComponent, DashboardComponent ] }).compileComponents(); }));
