Jmeter 测试

Jmeter安装

• 下载安装包解压即可。http://jmeter.apache.org/download_jmeter.cgi

Jmeter配置

• 配置线程组

  测试计划->添加->threads->线程组：

  如图所示则是200个用户，Ranmp-up Period是这么多用户在10s内提交完毕，循环10次

• 配置参数文件

  线程组->添加->配置元件->CSV Data Set Config

  配置相应的属性

• 配置HTTP请求

  线程组->添加->Sampler->HTTP请求

  配置相应的属性

image.png

• 添加输出报告

  线程组->添加->监听器->summary report

• 添加察看结果树

  线程组->添加->监听器->察看结果树

  通过结果树可以看到发送到服务器的请求，以及返回的结果。可以通过这个组件调试请求。

结果分析

结果如图所示：

samples：运行的线程总数5000。
Average：平均响应时间192ms。
Error：错误率0。
Throughout：吞吐量，每秒钟处理了1831个请求。

遇到的问题

• 编码问题

  1）查看参数文件的编码，一般用utf-8,。如果是txt文件，且编码不是utf-8，打开文件，另存为，设置编码格式为utf-8

  2）在CSV Data Set Config配置时，设置解析文件的格式为utf-8

  3）在HTTP请求配置，设置Content encoding为utf-8
