Node.js 使用Redis为NodeJS express服务器API编写mocha测试

我目前正在为我的团队正在开发的NodeJS应用程序编写集成测试

然而，我似乎不知道如何继续测试express服务器。服务器正在使用redis server进行缓存

看来，为了让我的测试成功，我应该运行redis server，并单独运行我的应用程序（通过nodemon应用程序），这没有意义，因为测试应该独立于任何外部运行命令

当我在不运行nodemon应用程序的情况下运行mocha测试时，应用程序永远不会进入glob功能，我得到：

  1) Deeplinq Server should return dubai search results via hippie:
     Uncaught Error: connect ECONNREFUSED
      at errnoException (net.js:904:11)
      at Object.afterConnect [as oncomplete] (net.js:895:19)

你可以看看我写的测试

    var site = require('../app/lib/site.js');
    var hippie = require('hippie');
    var http = require('http');
    var sinon = require('sinon');
    var index = require('../app/index.js');
    var server = require('../app/server.js');
    var expect = require('chai').expect;

describe('Deeplinq', function () {

    describe('Server', function () {

 it("should return dubai search results via hippie", function (done) {
            hippie(server)
                .auth('user', 'user')
                .get('http://dsg.deeplinq.dev:3000/en/search?q=dubai')
                .expectStatus(200)
                .expectHeader('text/html; charset=utf-8')
                .end(function (err, res, body) {
                    if (err) throw err;
                    done();
                })
        });
    });

});

谁能给我指一下正确的方向吗？我做错了什么，我能做些什么来解决这些问题呢？

好吧，在你的

server.js

中，你有：

redis.on（“connect”，function（）{

，所有的扫描都在里面进行。你认为在不运行redis服务器的情况下扫描会如何进行？：）@AndreyPopov即使在运行redis server时，我也会得到

Uncaught错误：connect ECONNREFUSED

glob函数从未被访问。我们在redis客户端上添加错误处理程序：

client.on（“Error”，函数（err）{

@AndreyPopov添加了一个错误处理程序，但什么也没做。我想这可能与glob函数的异步执行有关……为什么它从未被访问过？
