我尝试将 Jest 与 Spectator 一起使用来测试我的 Ionic 应用程序，但它在每次测试中都需要“@angular/animations”。

下面是一个简单的例子：

import { Spectator, createComponentFactory } from '@ngneat/spectator';
import { IonicModule } from '@ionic/angular';

import { NotificationsComponent } from './notifications.component';

describe('NotificationsComponent', () => {
    let spectator: Spectator<NotificationsComponent>;
    const createComponent = createComponentFactory({
        component: NotificationsComponent,
        imports: [IonicModule],
    });

    beforeEach(() => (spectator = createComponent()));

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

运行该测试时出现此错误：

jest src/app/components/notifications/notifications.component.spec.ts

 FAIL  src/app/components/notifications/notifications.component.spec.ts
  ● Test suite failed to run

    Cannot find module '@angular/animations' from 'node_modules/@angular/platform-browser/bundles/platform-browser-animations.umd.js'

我想知道如何在 Ionic 中使用 Jest/Spectator，谢谢！
