我正在使用Angular Jasmine编写uit测试。我收到以下错误：

  

NullInjectorError：   StaticInjectorError（DynamicTestModule）[UsersEffects-> actions]：             StaticInjectorError（平台：核心）[UsersEffects-> actions]：               NullInjectorError：没有操作提供者！

我的spec.ts文件是：

describe('UsersComponent',() => {
  let component: UsersComponent;
  let fixture: ComponentFixture<UsersComponent>;
  let dialogSpy: jasmine.Spy;
  let dialogRefSpyObj = jasmine.createSpyObj({ afterClosed : of({}),close: null });
  dialogRefSpyObj.componentInstance = { body: '' };

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [
        MaterialModule,Sharedmodule,ReactiveFormsModule,StoreModule.forRoot({}),StoreModule.forFeature('Users',reducer),HttpClientModule,UnitTestModule,BrowserAnimationsModule,TranslateModule.forRoot({
          loader: {
            provide: TranslateLoader,useclass: DummyTranslateLoader,},}),],schemas: [NO_ERRORS_SCHEMA],declarations: [],providers: [Store,UsersService],})
    .compileComponents();
  }));

  afterEach(() => {
    TestBed.resetTestingModule();
  });

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

  beforeEach(() => {
    dialogSpy = spyOn(TestBed.get(MatDialog),'open').and.returnValue(dialogRefSpyObj);
  });

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

我还添加了这是app.module.ts：

StoreModule.forRoot({}),EffectsModule.forRoot([]),

我可能会缺少什么？
