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。
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.html
python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@localhostbin]#./jmeter-n-tsingin.jmx
Creatingsummariser<summary>
Createdthetreesuccessfullyusingsingin.jmx
Startingthetest@MonDec1416:42:33CST2015(1450082553651)

...endofrun
由sumary统计行可以得到我们需要收集的测试结果：
主流程脚本

done
}
run_test

sleep1
#发送邮件
pythonsendmail.py
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
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
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@localhostloadtest]#catsummary.txt

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
4.3生成html报告

sum=`cat summary.txt | wc -l`
sucess=`cat summary.txt|grep pass |grep -v grep|wc -l`
