未捕获的TypeError：无法读取未定义抛出的属性'coSearchCriteria'

我试图使用Karma / Jasmine测试Angular组件 . 坦率地说，我对karma / jasmine并没有太多了解，同时测试得到的错误如“未捕获的TypeError：无法读取未定义抛出的属性'coSearchCriteria'” . 但正常的组件功能正常 . 如有任何想法请帮助我 .

这是我的测试代码，这里基本的'应该创建'测试用例正在运行，但第二个给出错误 .

describe('SearchPanelComponent', () => {
  let component: SearchPanelComponent;
  let fixture: ComponentFixture<SearchPanelComponent>;
  

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [ReactiveFormsModule, FormsModule, HttpModule, CarbonDatepickerModule, CarbonModalModule,CarbonIconModule, StoreModule.forRoot({})],
      declarations: [ SearchPanelComponent, UploadsearchcriteriaComponent ],
      providers: [ Store, StoreModule, CustomerorderService,ConnectionBackend, ApiConnectorService, HttpClient, HttpHandler,Http, CarbonModalService]    })
    .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(SearchPanelComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

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

it('RSSD To should be invalid', async( () => {
  const dateValue = component.orderUnitForm.controls['rssddateto'];
  dateValue.setValue('12-02/2012');
  fixture.detectChanges();
  expect(component.orderUnitForm.valid).toEqual(false);
}));

'coSearchCriteria'我在.ts文件中使用的只是这样

this.store.select(selectorCOCriteriaState)
    .subscribe((coSearchCriteria: SearchCriteriaState) => {   
       this.searchState = coSearchCriteria.lastUsedCriteria;     
    });   
    if(this.searchState){
        this.fillSearchStateData();  
    }

终于得到了修复，只需要在spec文件中模拟ngrx存储 .

class MockStore {
  public dispatch(obj) {
    console.log('dispatching from the mock store!')
  }

  public select(obj) {
    console.log('selecting from the mock store!');

    return Observable.of({})
  }
}
