angular – 模块’DynamicTestModule’导入的意外值’DecoratorF

let comp: TaskviewComponent;
let fixture: ComponentFixture;
let deTaskTitle: DebugElement;
let elSub: HTMLElement;

describe('TaskviewComponent',() => {

    beforeEach( () => {
        TestBed.configureTestingModule({
            declarations: [
                TaskviewComponent
            ],imports: [
                NgModule,RouterTestingModule,TranslateModule.forRoot(),],providers: [
                RestDataService,Restangular,{provide: OAuthService,useClass: OAuthServicMock},{provide: ComponentFixtureAutoDetect,useValue: true},{provide: UserInfoService,useClass: UserInfoServiceMock},{
                provide: LocalStorageService,//provide: LOCAL_STORAGE_SERVICE_CONFIG,useValue: {
                    prefix: ApplicationConstants.ANGULAR2_LOCAL_STORAGE_ID,storageType: 'sessionStorage'
                }
            }],})
            fixture = TestBed.createComponent(TaskviewComponent);
            comp = fixture.componentInstance;
            deTaskTitle = fixture.debugElement.query((By.css('.Subject')));
            elSub = deTaskTitle.nativeElement;

});

it('should have a subject',() => {
     expect(elSub.textContent).toContain('Client Data Maintenance2 ');
});
});

我收到错误：由模块’DynamicTestModule’错误导入的意外值’DecoratorFactory’.我注意到如果我删除“fixture = TestBed.createComponent(TaskviewComponent);”错误将得到解决.但这不会创建测试组件.另外,我注意到如果我在import []中不包含NgModule,则不会识别Ngmodel,datepicker等元素.
