node.js - 'FIRESTORE 内部断言失败 : Unexpected state' when unit testing with Jest

Question

我为我正在构建的 Node.js 和 Express REST API 设置了一个 Jest 测试套件，我正在使用 @firebase/testing 模块来初始化一个测试应用程序，但是当我尝试对数据库出现此错误:

FIRESTORE (7.17.2) INTERNAL ASSERTION FAILED: Unexpected state
      at fail (/home/cardonapablo/Documentos/Proyectos/Optica (Ilicit)../../../../../node_modules/@firebase/testing/node_modules/@firebase/firestore/src/util/assert.ts:39:9)

我还尝试使用我一直用来开发端点的凭据连接到我的常规 Firestore 数据库，即使它是我每天使用的应用程序，也会弹出相同的错误
奇怪的是，数据正在写入数据库，但错误仍然停止测试
这是火力基地设置:

(src/db/functions.js)

let app  = initializeTestApp({ 
    projectId: "illicit"
})
db = app.firestore()
module.exports = { db }

抛出错误的函数

(tests/fixtures/db.js)

const { db } = require('../../src/db/functions')
const bcrypt = require('bcrypt');

const createAdmin = async function() {

    // Encrypt password
    let encPass = await bcrypt.hash("admin", 8)

    let admin = {
        name: "Admin Test User",
        email: "admin@test.com",
        password: encPass,
        tokens: []
    }

    // Add to db
    let docRef = await db.collection('admins').add(admin) // <- This line throws the error
    return;
}

module.exports = {
    createAdmin
}

最后测试文件

(tests/glasses.test.js)
const supertest = require('supertest');
const app = require('../src/app')
const functions = require('./fixtures/db')

let adminToken;
let glassesId;

//Executes before any test, here is where error occurs, before any tests
beforeAll( async () => {
    await functions.createAdmin()
    return
})

test('Should log in an admin', async () => {
    let response = await supertest(app)
    .post('/admins/login')
    .send({
        email: 'admin@test.com',
        password: 'admin'
    })
    .expect(200);
    expect(response.body.token).toEqual(expect.any(String))
    adminToken = response.token;
});

这只发生在我尝试测试时，常规应用程序工作正常
我尝试过的事情:

Firestore 规则读写为真，所以不是规则错误

使用 firebase-mock 和 Jest 模拟 Firestore 似乎工作正常，但这不是
解决方案，因为我需要测试数据库中的数据

希望你能帮我 :)

您应该更改 Jest 的默认测试环境 jsdom至node使用 jest --env=node或通过设置 testEnvironment node 的选项在您的 Jest 配置中。
