Javascript - 測試讀取文件與業力+ PhantomJS

Question

我需要從js專家的幫助。 我有一個js文件：

'use strict'; 

var fs = require('fs'); 

var Conf = {  
    read: read, 
}; 

function read() { 
    try { 
     var conf = JSON.parse(fs.readFileSync(__dirname + '/../resources/conf.json', 'utf-8')); 
     return conf; 
    } 
    catch (err) { 
     console.log('There has been an error parsing your JSON.'); 
     console.log(err); 
    } 
} 

module.exports = Conf; 

我想測試它。我使用業力+摩卡。我創建的測試文件

'use strict'; 

var Conf = require('../../lib/Conf'); 

describe('My test', function() { 

    describe('json config', function() { 
     it('should display initially', function() { 
      console.log(Conf.read()); 
     }); 
    }); 
}); 

但我總是得到類型錯誤錯誤時，PhantomJS 2.1.1運行測試，如果我改變PhantomJS Chrome瀏覽器得到了一個未定義的錯誤。

測試框架支持require('fs');？如果是，請幫助我，請運行它。

我的人緣配置是

我解決了這個問題的變化變換值：

browserify: { debug: true, transform: [ [ 'stringify', { global: true, extensions: [ '.bpmn', '.xml', '.css' ] } ] ] }

到

browserify: { debug: true, transform: [ 'brfs' ] }
