测试快速服务器时需要获取 426 更新

Question

所以我正在使用 express 构建一个简单的网络应用程序，并希望从一开始就进行单元测试。所以我创建了一个简单的测试来查看“/”是否返回 200。但我的测试总是说他们收到 426。我在网上找不到关于这个问题的任何信息，并且相信我正确设置了服务器。

这是我的服务器：

// server.js    
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const winston = require('winston')

const app = express();

const logger = winston.createLogger({
    level: 'info',
    format: winston.format.json(),
    defaultMeta: { service: 'user-service' },
    transports: [
        new winston.transports.File({ filename: 'error.log', level: 'error' }),
        new winston.transports.File({ filename: 'combined.log' })
    ]
})

if (process.env.NODE_ENV !== 'production') {
    logger.add(new winston.transports.Console({
        format: winston.format.simple()
    }))
}

app.use(
  bodyParser.urlencoded({
    extended: false,
  })
);
app.use(bodyParser.json());
app.use(cors());

app.get('/', (req, res) => {
    logger.info("recieved get to /")
    res.send('ok')
});

const port = 3000;

const server = app.listen(port, err => {
  if (err) {
    console.log(err);
  } else {
    console.log(`Running on port ${port}`);
  }
});
module.exports = server

这是我的测试：

const request = require('supertest')

describe('loading express', () => {
    let server;
    process.env.NODE_ENV = 'test'
    beforeEach(() => {
        delete require.cache[require.resolve('../server')]; // clear the cache of server instance
        server = require('../server')
    })
    afterEach((done) => {
        server.close(done)
    })
    it('responds to /', (done) => {
        request(server)
            .get('/')
            .expect(200, done)
    })
    it('404 everything else', (done) => {
        request(server)
            .get('/foo/bar')
            .expect(404, done)
    })
})

我的测试总是返回：

0 passing (1s)
  2 failing

  1) loading express
       responds to /:
     Error: expected 200 "OK", got 426 "Upgrade Required"

您好，答案可以在这里Getting over a 426 upgrade required 找到。看来很多工作PC的3000端口都有问题。
