node.js - Karma 无法捕获 PhantomJS

Question

我们已经设置了一个运行 Karma 的 Jenkins CI 服务器，目标是 PhantomJS。我们正在通过 Grunt 运行我们的测试。Jenkins、Grunt 和 Phantom 都运行正常，而且 Karma 似乎启动良好，但 Karma 无法捕获 Phantom。我们的脚本在本地（OSX）运行得很好。通过 bash 或 Jenkins 运行时存在相同的错误：

我们的服务器是 CentOS 6.4。

以下是我们运行的版本：grunt-cli v0.1.9 grunt v0.4.1 node 0.10.12 和 0.8.25。phantomjs 1.9.1 业力 0.8.6

任何帮助将非常感激！

在配置文件中使用轮询而不是套接字和绝对路径而不是相对路径，karma.conf.js以确保正确遍历目录结构并且客户端/服务器连接没有外部依赖项：

module.exports = function(config) 
  {
  var absolute_root = process.cwd() + '/';
  config.set
  (
    {
    // https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],

    // list of files

    files: 
       [
       absolute_root + 'test/Spec/**/*.js',
       absolute_root + 'js/*.js',
       absolute_root + '../libs/jquery.js'
       ],

     usePolling: true,

     transports: ['xhr-polling', 'jsonp-polling'],

     browsers: ['PhantomJS']
    }
  );
  };

在我的情况下添加

transports: ['xhr-polling', 'jsonp-polling']

就karma.conf.js足够了。真正的问题是业力的一个非常旧的版本（0.12）。现在有了 1.4。我不需要消耗 CPU 的轮询。
