具有存储调度操作的角度单元测试组件

onClearSearch() {
  this.store$.dispatch(some action);
}

尝试对组件进行单元测试并触发存储调度不起作用。我的组件测试如下所示:

let store: MockStore<State>;

beforeEach(waitForAsync(() => {
  TestBed.configureTestModule({
    ...
    providers: [
      SearchStoreEffects,
      provideMockActions(() => actions$),
      provideMockStore({initialState, selectors: [...]})
    ],
    ...
  }).compileComponents();

  ...
  store = TestBed.inject(MockStore);
  fixture.detectChanges();
}));

it('should clear search value', () => {
  const storeSpy = spyOn(store, 'dispatch').and.callThrough();
  component.onClearSearch();
  fixture.detectChanges();
  expect(storeSpy).toHaveBeenCalledTimes(1);
});
