基于jmeter和shell的接口性能自动化

1. 总体需求

由于性能测试中涉及的查询接口多，版本迭代频繁，版本更新后自动跑一轮查询业务的性能，可以及时发现一些开发修复bug触发的非预期的bug，利用晚上时间快速重测性能接口可以解放人工测试的时间，让测试人员可以把精力集中在测试复杂接口，调优分析性能瓶颈上。

2. 实现流程

自动化的场景模拟真实手工测试，操作步骤和手工测试一样。

开始读取接口测试用例执行用例，发起服务器监控收集执行结果和监控结果执行完所有用例？整理结果，发送邮件结束yesno

3.准备工作

准备软件：

系统环境：CentOS release 6.7 (Final)内核版本：Linux localhost 2.6.32-573.7.1.el6.x86_64测试工具：apache-jmeter-2.13 http://jmeter.apache.org/download_jmeter.cgi运行JDK环境：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.htmlpython环境：Python 2.6.6服务器监控nmon：http://nmon.sourceforge.net/pmwiki.php?n=Site.Download

4.具体实现

4.1用例执行

Jmeter的执行支持命令行的方式执行，并且会有一个粗略报告，我们取这个报告里面的执行结果并保存下来  Jmeter的执行结果：

[root@localhost bin]# ./jmeter -n -t singin.jmx Creating summariser <summary> Created the tree successfully using singin.jmx Starting the test @ Mon Dec 14 16:42:33 CST 2015 (1450082553651) Waiting for possible shutdown message on port 4445 summary + 1 in 1s = 1.3/s Avg: 268 Min: 268 Max: 268 Err: 0 (0.00%) Active: 1 Started: 1 Finished: 0 summary + 2 in 0s = 50.0/s Avg: 17 Min: 14 Max: 20 Err: 0 (0.00%) Active: 0 Started: 1 Finished: 1 summary = 3 in 1s = 3.7/s Avg: 100 Min: 14 Max: 268 Err: 0 (0.00%) Tidying up ... @ Mon Dec 14 16:42:34 CST 2015 (1450082554551) ... end of run 12345678910 12345678910

由sumary统计行可以得到我们需要收集的测试结果：

测试结果项 值 总请求数 3 平均tps 3.7 平均响应时间 100ms 请求失败率 0.00%

主流程脚本

#/bin/bash source /etc/profile Jmeter_Home='/usr/local/apache-jmeter-2.13' TestReport='/data/loadtest/report' LogDIR='/data/loadtest/log' Date=`date +"%F"` cd /data/loadtest/ >summary.txt #清理上次执行结果 run_test() { #获取测试用例 for i in `find ./testcase/ -name *.jmx|awk -F '.'

4.2服务器监控

服务器资源收集方面，选用的是nmon监控工具，因为它可以后台收集结果保存到文件。由于每个用例测试5分钟，所以只需要监控300秒，每5s监控一次，对应命令：

nmon -f -t -s5 -c60 -F /data/test.nmon 1 1

测试用例跑完再读取这个结果文件，获取有用的信息  当前只统计了磁盘io和cpu的占用率信息，原始文件保存在本地目录，如果需要，可以手动查看到。  监控脚本：

#!/bin/bash #读取监控服务器列表 SERVERLIST=`cat serverlist` DATE=`date +'%F'` mkdir -p /data/loadtest/monitor/$DATE TIME=`date +'%T'` #发起监控 for i in $SERVERLIST do ssh $i 'nmon -f -t -s5 -c60 -F /data/test.nmon >/dev/null 2>&1 &' done #监控5分钟 sleep 303 >monitor.txt #收集监控结果，保存到monitor.txt for i in $SERVERLIST do scp $i:/data/test.nmon /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon io=`cat /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon|grep "DISKBUSY,T" | awk -F ',' '{sum+=$3} END {printf("%.2f%",sum/NR)}'` cpu=`cat /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon|grep "CPU_ALL,T" | awk -F ',' '{sum+=$6} END {printf("%.2f%",100-sum/NR)}'` #net=`cat /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon|grep "NET,T"|awk -F ',' '{sum_r+=$4}{sum_w+=$6} END {print sum_r/NR,sum_w/NR}'` echo -n "${cpu} ${io} ">>monitor.txt done 1234567891011121314151617181920212223 1234567891011121314151617181920212223

将用例执行结果和监控结果都汇总到summary.txt里  生成的格式如下，方便后面生成html格式的报告

[root@localhost loadtest]# cat summary.txt /testcase/user/获取用户自己的信息 10748.6 8 3225296 0 100.00% pass 32.87% 5.34% 81.59% 2.12% 0.15% 1.78% 12.13% 32.83% 17.18% 6.14% /testcase/user/未读消息数 11487.4 7 3446960 0 100.00% pass 32.33% 12.57% 69.02% 1.86% 0.18% 1.74% 13.55% 35.85% 18.56% 7.65% 123 123

服务器监控脚本

#!/bin/bash SERVERLIST=`cat serverlist` DATE=`date +'%F'` mkdir -p /data/loadtest/monitor/$DATE TIME=`date +'%T'` for i in $SERVERLIST do ssh $i 'nmon -f -t -s5 -c60 -F /data/test.nmon >/dev/null 2>&1 &' done sleep 303 >monitor.txt for i in $SERVERLIST do scp $i:/data/test.nmon /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon io=`cat /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon|grep "DISKBUSY,T" | awk -F ',' '{sum+=$3} END {printf("%.2f%",sum/NR)}'` cpu=`cat /data/loadtest/monitor/$DATE/${i}_${TIME}.nmon|grep "CPU_ALL,T" | awk -F ',' '{sum+=$6} END {printf("%.2f%",100-sum/NR)}'` echo -n "${cpu} ${io} ">>monitor.txt done 123456789101112131415161718192021 123456789101112131415161718192021
