我正在用Jest和Enzyme测试我的React应用程序。我也使用Firebase，当我尝试为使用带有Firebase登录的Header组件的页面编写测试时，我得到以下错误：
测试套件运行失败

这是我的Firebase配置文件：

import firebase from 'firebase/compat/app';
import 'firebase/compat/firestore';
import 'firebase/compat/auth';

const config = {
    ...
  }

export const createUserProfileDocument = async (userAuth, additionalData) => {
  if (!userAuth) return;

  const userRef = firestore.doc(`users/${userAuth.uid}`); 
  
  const snapShot = await userRef.get();

  if(!snapShot.exist) {
    const { displayName, email } = userAuth;
    const createdAt = new Date();

    try {
      await userRef.set({
        displayName,
        email,
        createdAt,
        ...additionalData
      })
    } catch (error) {
      console.log("error creating user", error.message);
    }
  }

  return userRef;

}

firebase.initializeApp(config);

export const auth = firebase.auth();
export const firestore = firebase.firestore();

const provider = new firebase.auth.GoogleAuthProvider();
provider.setCustomParameters({ prompt: 'select_account' });
export const signInWithGoogle = () => auth.signInWithPopup(provider);

export default firebase;

我现在使用的是Firebase 9.8.0。
有没有什么想法，我错过了什么？应用程序本身和认证流程工作正常。
