Integration testing

We can also write an integration test that will exercise the whole application.

import {TestBed, async, ComponentFixture, inject} from '@angular/core/testing';
import {AppCmp} from './app.component';
import {AppModule} from './app.module';
import {App} from "./app";

describe('AppCmp', () => {
  let component: AppCmp;
  let fixture: ComponentFixture<AppCmp>;
  let el: Element;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [AppModule]
    });
    TestBed.compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(AppCmp);
    component = fixture.componentInstance;
    fixture.detectChanges();
    el = fixture.debugElement.nativeElement;
  });

  it('should filter talks by title', async(inject([App], \
    (app: App) => {
    app.model.talks = [
      {
        "id": 1,
    ...
