Expresso测试在导航到静态文件时返回“Error: Response not completed”

Question

我正在尝试设置一个简单的项目，使用Node.js和Express与Express进行测试。我正在使用express.static中间件提供位于我的公共目录中的静态html文件(index.html)。这是app.js的代码：

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

// Configuration
app.configure(function() {
    app.use(express.staticCache());
    app.use(express.static(__dirname + '/public'));
    app.use(express.bodyParser());
});

app.listen(3000);

然后，我编写了一个简单的测试来检查静态文件。这是app.test.js的代码：

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

module.exports = {

    'Navigate to root': function() {
        assert.response( 
            app,
            {
                url: '/'
            },
            {
                status: 200,
                headers: { 'Content-Type': 'text/html; charset=utf8'}
            },

            function(res) {
                assert.includes(res.body, 'index');
                assert.ok(res);
            }
        );
    }
};

当我运行测试(使用expresso或expresso -s)时，我得到以下错误：

app.test.js Navigate to root: TypeError: Object #<Object> has no method 'listen'

    at Array.forEach (native)

我显然在做一些愚蠢的事情，但我似乎不知道它是什么。我想这可能是因为我的服务器在测试之前已经启动了，但看起来Expresso可以处理这种情况。我还使用json测试了一个REST端点，以查看是否是静态文件导致了问题，但它给出了相同的错误。

我使用的是Expresso0.6.6、Node.js 2.5.4和Expresso0.9.2。谢谢!

您没有从app.js文件中导出app

把这个加到最后

module.exports = app;
