tdd - 使用 expresso - redis session 存储测试 node.js

Question

我正在尝试使用 node.js 学习 TDD。我在 expresso 中遇到了 expresso 命令挂起的问题，我想是因为 redis-server。使用 ctrl+C 终止进程最终得到我正在寻找的输出(100% 3 次测试通过)。

是什么导致 expresso 命令挂起，我该怎么办？

我的应用看起来像这样:

// Module dependencies.

var auth = require('connect-auth'),
    RedisStore = require('connect-redis');


var express = require('express');
var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(express.session({ store: new RedisStore, secret: "secret goes here" }));
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

app.configure('development', function(){
  app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); 
});

app.configure('production', function(){
  app.use(express.errorHandler()); 
});

// Routes

app.get('/', function(req, res){
  res.render('index', {
    title: 'Orchestrate'
  });
});

app.get('/login', function(req, res){
  res.render('user/login', {
    title: 'Login'
  });
});

app.get('/register', function(req, res){
  res.render('user/login', {
    title: 'Register'
  });
});

// Only listen on $ node app.js

if (!module.parent) {
  app.listen(3000);
  console.log("Express server listening on port %d", app.address().port);
}

还有我的测试:

// Run $ expresso

/**
 * Module dependencies.
 */

var app = require('../app'),
    assert = require('assert');


module.exports = {
  'GET /': function(){
    assert.response(app,
      { url: '/' },
      { status: 200, headers: { 'Content-Type': 'text/html; charset=utf-8' }},
      function(res){
        assert.includes(res.body, '<title>Orchestrate</title>');
      });
  },
  'GET /login': function(){
    assert.response(app,
      { url: '/login' },
      { status: 200, headers: { 'Content-Type': 'text/html; charset=utf-8' }},
      function(res){
        assert.includes(res.body, '<title>Login</title>');
      });
  },
  'GET /register': function(){
    assert.response(app,
      { url: '/register' },
      { status: 200, headers: { 'Content-Type': 'text/html; charset=utf-8' }},
      function(res){
        assert.includes(res.body, '<title>Register</title>');
      });
  }

};

尝试像这样编写测试，当所有测试完成后，测试运行器应该自行终止:

  'GET /': function(done){
    assert.response(app,
      { url: '/' },
      { status: 200, headers: { 'Content-Type': 'text/html; charset=utf-8' }},
      function(res){
        assert.includes(res.body, '<title>Orchestrate</title>');

        done();
      });
