Unexpected value 'DecoratorFactory' imported by the module 'DynamicTestModule' - karma-jasmine

Question

I'm getting error during creating Test component instance.

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 ');
});
});

I'm getting Error: Unexpected value 'DecoratorFactory' imported by the module 'DynamicTestModule' error. I notice that if I remove "fixture = TestBed.createComponent(TaskviewComponent);" error would be resolved. but this will not create the Test Component. Also, I notice that if I don't include NgModule in imports[], elements like Ngmodel, datepicker etc.are not recognized.

You can't import "NgModule" as it is a decorator and not a module.
