关于node.js：尝试使用chai-http测试节点js表达路由时无响应

No response when try test nodejs express4 route with chai-http

如果尝试运行应用程序并执行本机(POstMan)测试，则我尝试对nodejs express4路由进行运行测试，但无法获得响应-就像Sharm一样工作。

import express = require('express');
import expressValidator = require('express-validator');
import bodyParser = require('body-parser');
let app = express();

app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(expressValidator())

app.get("/", (req, res) => res.status(200).send({message:"Hello"}));

app.route("/book")
.get((req,res)=>{console.log(req.path);return res.status(200)})
.post((req,res)=>{return res.status(

//Run
app.listen(3000, function() {
console.log('Listening on port '+ 3000)
})

export = app;

import chai = require('chai');
import chaiHttp = require('chai-http');
import mocha = require('mocha');

let server = require('../dist/app');
let expect = chai.expect;

chai.use(chaiHttp);

describe('/GET', () => {
it('it should not GET a book without pages field', (done) => {
chai.request(server)
.get('/book')
.end(function(err, res) {
expect(res).to.have.status(200);
done(); // <= Call done to signal callback end
});
});
});

结果是我得到错误

Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure
"done()" is called; if returning a Promise, ensure it resolves.

/book不会将任何响应发送回客户端。这就是您的测试用例超时的原因。

res.status(200)仅将http响应代码设置为200，但不发送
任何回应。您可以尝试resp.sendStatus(200)。
