如何测试NgRX中是否调度了操作？

import { Store } from '@ngrx/store';

describe('NgRX Testing', () => {
  let store: Store;

  beforeEach(() => {
    // 初始化store
    store = new Store();
  });

  it('should dispatch an action', () => {
    spyOn(store, 'dispatch');

    // 调用需要测试的函数

    expect(store.dispatch).toHaveBeenCalled();
  });
});

import { ActionsSubject } from '@ngrx/store';

describe('NgRX Testing', () => {
  let actions$: ActionsSubject;

  beforeEach(() => {
    // 初始化actions$
    actions$ = new ActionsSubject();
  });

  it('should dispatch an action', () => {
    let actionDispatched = false;

    actions$.subscribe(action => {
      // 检查是否有操作被调度
      actionDispatched = true;
    });

    // 调用需要测试的函数

    expect(actionDispatched).toBe(true);
  });
});
