尝试使用 chai-http 测试节点 js express 4 路由时无响应

Question

我尝试运行测试 nodejs express4 路由但无法得到响应，如果尝试运行应用程序并执行本机 (POstMan) 测试 - 工作得很好。

APP.ts

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;

test.ts

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
                        });
            });
  });

结果我收到错误

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)只设置http响应码为200，不发送任何回应。你可以试试 resp.sendStatus(200).
