firebase.storage()不是jest测试用例中的函数

Question

我正在使用Jest来测试我的firebase功能.这一切都在浏览器中,因此我与服务器端的firebase没有任何冲突.当我使用firebase.auth()或firebase.database()一切正常.当我尝试使用firebase.storage()我的测试失败.

这是我的firebase导入和初始化:

import firebase from 'firebase';
import config from '../config';

export const firebaseApp = firebase.initializeApp(config.FIREBASE_CONFIG);
export const firebaseAuth = firebaseApp.auth();
export const firebaseDb = firebaseApp.database();

我有一个imageUtils文件,其中包含上传功能:

import { firebaseApp } from './firebase';

export const uploadImage = (firebaseStoragePath, imageURL) => {
  return new Promise((resolve, reject) => {
    // reject if there is no imagePath provided
    if (!firebaseStoragePath) reject('No image path was provided. Cannot upload the file.');

    // reject if there is no imageURL provided
    if (!imageURL) reject('No image url was provided. Cannot upload the file');

    // create the reference
    const imageRef = firebaseApp.storage().ref().child(firebaseStoragePath);

    let uploadTask;
    // check if this is a dataURL
    if (isDataURL(imageURL)) {
      // the image is a base64 image string
      // create the upload task
      uploadTask = imageRef.putString(imageURL);
    } else {
      // the image is a file
      // create the upload task
      uploadTask = imageRef.put(imageURL);
    }

    // monitor the upload process for state changes
    const unsub = uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED,
      (snapshot) => {
        // this is where we can check on progress
      }, (error) => {
        reject(error.serverResponse);
        unsub();
      }, () => {
        // success function
        resolve(uploadTask.snapshot.downloadURL);
        unsub();
      });
  });
};

我正在尝试为该函数创建一个测试用例,并且每次失败时:

TypeError: _firebase3.firebaseApp.storage is not a function

当我运行应用程序时,一切正常,我从来没有得到关于存储()未定义或不是函数的错误.只有当我尝试运行测试用例时.

我已经设置了console.dir(firebaseApp);在火力进口线,并与这两个回来auth()和database(),但没有储存.如何正确导入/初始化/存在存储？

添加以下导入

import "firebase/storage";
