前段时间做了一个服务器端接口，是附带文件上传的；后来我们要对这个接口进行压力测试；
　　其实很多现成的方式可以做压力测试，但是附带文件的的压力测试缺不怎么符合我的需求，jmeter是可以做附带文件上传的压力测试的，只是它是图形界面，而我目前的需求是要在测试机器上面去跑测试，而测试服务器是不能带图形界面的，所以jmeter的方案否决掉；
　　apache ab test，也是一个压力测试的好工具，只是研究了好久老搞不掂怎么做附带文件上传的压力测试（备注：在本文的后我附带一下我研究的结果，说多了都是泪）
　　好了，现在我说下我自己的这个测试工具：
　　它依赖于赖于httpclient相关的包，包括：commons-codec-1.6.jar、commons-logging-1.1.3.jar、fluent-hc-4.3.4.jar、httpclient-4.3.4.jar、httpclient-cache-4.3.4.jar、httpcore-4.3.2.jar、httpmime-4.3.4.jar、httpmime-4.3.4.jar；
　　大家可以到apache的官方网站：http://hc.apache.org/downloads.cgi  去下载相关的包；
