Question

我正在尝试使用玩笑进行集成测试（restApi测试）。我正在本地连接数据库。当我运行测试时，它显示出这样的错误，例如“监听EADDRINUSE：地址已在使用::: 5000。

product.test.js

const request=require('supertest')
let server;


    describe('all data',()=>{
            beforeEach(()=>{server=require('../../index');})
            afterEach(()=>{server.close();})
        it('should return all the data', async()=>{
            const result=await request(server).get('/product');
            expect(result.status).toBe(200)

        })
    })

index.js

var express = require('express')
var MongoClient = require('mongodb').MongoClient;
var body_parser = require('body-parser')
const product = require('./routes/product.js')
const register = require('./routes/registeration.js')
const login = require('./routes/login.js')

var app = express()

app.use(body_parser.json())
app.use('/product', product);
app.use('/register',register)
app.use('/login',login)




const port = process.env.PORT || 5000;
const server = app.listen(port, () => console.log(`Listening on port ${port}...`));

module.exports=server;

product.js

var express = require('express')
var validate = require('../models/product.js')
const router = express.Router();
const MongoClient = require('mongodb').MongoClient;
var ObjectId = require('mongodb').ObjectID
var validate_token = require('../jwt/jwttoken.js')
var file = require('../log_file/logfile.js')
var config=require('config')
const client = new MongoClient(config.get('db'), { useNewUrlParser: true })


router.get('/', async (req, res, next) => {

  try {
    await client.connect();
    const db = client.db('olc_prod_db');
    const r = await db.collection('Ecommerce').find().toArray();
    res.send(r)
  } catch (err) {
    console.log(err.stack);
  }

});

使用Jest运行测试套件时出现EADDRINUSE错误
