node.js: Mock http request and response
提问by 7elephant
Is there convenient way to mock the HTTP Request and Response objects for unit testing middlewares?
是否有方便的方法来模拟单元测试中间件的 HTTP 请求和响应对象？

It looks like both https://github.com/howardabrams/node-mocks-httpand https://github.com/vojtajina/node-mockscan be used to create mock http.ServerRequestand http.ServerResponseobjects.
看起来https://github.com/howardabrams/node-mocks-http和https://github.com/vojtajina/node-mocks都可以用来创建模拟http.ServerRequest和http.ServerResponse对象。

From the tag, it looks like this question is about Express. In that case, supertestis very good:
从标签上看，这个问题似乎是关于 Express 的。在这种情况下，supertest非常好：
var request = require('supertest')
, express = require('express');
var app = express();
app.get('/user', function(req, res){
res.send(201, { name: 'tobi' });
});
request(app)
.get('/user')
.expect('Content-Type', /json/)
.expect('Content-Length', '20')
.expect(201)
.end(function(err, res){
if (err) throw err;
});
For general Node use, Flatiron Nocklooks like a good option:
对于一般 Node 使用，Flatiron Nock看起来是一个不错的选择：
var nock = require('nock');
var example = nock('http://example.com')
.get('/foo')
.reply(200, { foo: 'bar' });
var http = require('http');
var options = {
host: 'example.com',
port: 80,
path: '/foo',
method: 'GET'
}
var req = http.request(options, function(res) {
res.on('data', function(chunk) {
console.log('BODY: ' + chunk);
});
});
req.on('error', function(e) {
console.log('error: ' + e);
});
req.end();
Output:
输出：
BODY: {"foo":"bar"}
正文：{"foo":"bar"}

I wrote a library to mock out the responses of requests made via standard HTTP or via the request model:
我编写了一个库来模拟通过标准 HTTP 或通过请求模型发出的请求的响应：
