Question

Angular 2和核心测试都是新手。

我有一个使用注入的MovieService的MovieComponent。试图学习，所以使用路线参数。代码正在按预期工作。

describe('MovieComponent', () => {
let component: MovieComponent;
let fixture: ComponentFixture<MovieComponent>;
let options: RequestOptions;
beforeEach(async(() => {
TestBed.configureTestingModule({
  declarations: [ MovieComponent ],
imports: [
HttpModule
],
providers: [
{
  provide: ActivatedRoute, useValue: {
  params: Observable.of({ movieName: 'Bah' })
  }
}, MovieService, Http, {provide: ConnectionBackend},
],
   schemas :[NO_ERRORS_SCHEMA ]
 })
.compileComponents();
}));

beforeEach(() => {
 options = new RequestOptions({method: RequestMethod.Get});
 fixture = TestBed.createComponent(MovieComponent);
 component = fixture.componentInstance;
 fixture.detectChanges();
});

 it('should create', () => {
   expect(component).toBeTruthy();
  });
});

但是，我收到了这个测试错误：

TypeError: Cannot read property 'getMovies' of undefined

提前致谢。

您是否在编译器中运行它？它编译？我不这么认为 onActivityResult是对的。只需传递MovieService，如下所示：`

^([0-9]+y\s?)?(((1[0-2])|([1-9]))m\s?)?((([12]?[0-9])|(3[01]))d)?$

`
