karma配置参数笔记

    files.push('index.html');
    files.push('../../test/*.coffee');

    otherJsFiles.forEach(function(file){
        files.push({

            served: true,

上面是我的配置文件
<!--more--> 首先，说明下basePath参数。这个参数设置了web/htdocs/，这个作用是在files和exclude两个参数里面不用再写这部分路径的匹配了。
但是，我这个项目的test目录在web/htdocs/外,所以还要补上../../。否则会匹配不上。

然后，我们再看看files参数下面这三个参数pattern、served和included这三个参数.
pattern是要匹配的文件和匹配模式
served用于该文件是否由karma webserver提供
included浏览器是否需要通过<script>标签引入该文件

为什么我要将部分文件设置成included:false手动加载呢？
这是因为部分js文件加载是由newifi.js，通过ajax加载进去的。如果，直接included进karma webserver就会报错（找不到函数或者变量没定义）。
但是，这样还是不能正常加载这些js文件的。在执行newifi.js时，ajax加载这部分js文件会提示404. 这是因为karma将加载后的文件移到http:\\localhost:[port]\base下了。所以，你还要设置proxies参数.将ajax加载/newifi下的js文件指向/base/newifi
