Loadrunner进行http接口压力测试

1、使用Loadrunner进行http接口压力测试业务描述：在业务系统里进行查询操作，查询的结果是通过请求http接口，从系统中处理并将结果以json字符串返回。使用Loadrunner对此类接口进行压力测试并记录相关的性能指标数据：1 .安装Loadrunner本次测试过程使用Loadrunner11.0版本。2 .部署环境1 .接口服务器一台；2 .用于运行Loadrunner的压力测试机1台或N台，在条件允许下，尽可能提供高配置的CPU和内存。3 .接口服务器和压力测试机建议应部署于同一个局域网内，否则测试过程和结果将受到网络带宽因素的影响无法顺利进行。三.编写测试脚本方法一.通过java

2、编写测试类，以jar包的方式引入Loadrunner进行测试。优点：便于解析接口响应结果，同时避免由于LR脚本编写不规范或配置问题，导致测试过程引发的未知错误。条件：运行loadrunner的机器需要安装jdk1.6的版本。1.编写java测试类：CTLPTest.java,如下代码1 packagecom;23 importjava.io.InputStream;4 .HttpURLConnection;5 .URL;6 importjava.util.Random;78 publicclassCTLPTest9 10 publicstaticvoidmain(Stringargs)11 1
