如何在React Native中测试删除查询Firebase/mockFirebase？

npm install --save firebase react-native-mock firebase-mock

import firebase from 'firebase';

const firebaseConfig = {
  // 在此处添加你的Firebase配置信息
};

firebase.initializeApp(firebaseConfig);

export default firebase;

import firebase from 'firebase-mock';

const mockAuth = new firebase.MockAuthentication();
const mockFirestore = new firebase.MockFirestore();
const mockStorage = new firebase.MockStorage();

export const mockFirebase = new firebase.MockFirebaseSdk(
  // 在此处添加你的Firebase配置信息
  () => mockAuth,
  () => mockFirestore,
  () => mockStorage
);

import firebase from '../firebaseConfig';
import { mockFirebase } from '../firebase-mock';

// 使用mockFirebase替换Firebase模块
jest.mock('../firebaseConfig', () => mockFirebase);

describe('Firebase测试', () => {
  it('删除数据', async () => {
    // 模拟删除数据
    await firebase.firestore().collection('users').doc('user1').delete();

    // 断言删除后数据是否不存在
    const snapshot = await firebase.firestore().collection('users').doc('user1').get();
    expect(snapshot.exists).toBe(false);
  });

  it('查询数据', async () => {
    // 模拟查询数据
    const snapshot = await firebase.firestore().collection('users').doc('user1').get();

    // 断言查询结果是否正确
    expect(snapshot.exists).toBe(true);
    expect(snapshot.data()).toEqual({ name: 'John Doe' });
  });
});
