基于jmeter和shell的接口性能自动化
1. 总体需求
由于性能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
-
运行JDK环境：
-
python环境：Python 2.6.6
-
服务器监控nmon：
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

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

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
-
