jmeter+shell

1. 總體需求

由於效能測試中涉及的查詢介面多，版本迭代頻繁，版本更新後自動跑一輪查詢業務的效能，可以及時發現一些開發修復bug觸發的非預期的bug，利用晚上時間快速重測效能介面可以解放人工測試的時間，讓測試人員可以把精力集中在測試複雜介面，調優分析效能瓶頸上。

2. 實現流程

自動化的場景模擬真實手工測試，操作步驟和手工測試一樣。

3.準備工作

準備軟體：

系統環境：CentOS release 6.7 (Final)
核心版本：Linux localhost 2.6.32-573.7.1.el6.x86_64
測試工具：apache-jmeter-2.13 

4.具體實現

4.1用例執行

Jmeter的執行支援命令列的方式執行，並且會有一個粗略報告，我們取這個報告裡面的執行結果並儲存下來 
Jmeter的執行結果：

 bin]# ./jmeter -n -t singin.jmx

由sumary統計行可以得到我們需要收集的測試結果：

4.2伺服器監控

伺服器資源收集方面，選用的是nmon監控工具，因為它可以後臺收集結果儲存到檔案。由於每個用例測試5分鐘，所以只需要監控300秒，每5s監控一次，對應命令：

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

測試用例跑完再讀取這個結果檔案，獲取有用的資訊 
當前只統計了磁碟io和cpu的佔用率資訊，原始檔案儲存在本地目錄，如果需要，可以手動檢視到。

監控指令碼：

#!/bin/bash
#讀取監控伺服器列表
SERVERLIST=`cat serverlist`
DATE=`date +'%F'`
mkdir -p /data/loadtest/monitor/$DATE
TIME=`date +'%T'`
#發起監控
for i in $SERVERLIST
do 
  ssh $i 'nmon -f -t -s5 -c60 -F /data/test.nmon >/dev/null 2>&1 &'
done
#監控5分鐘
sleep 303
>monitor.txt
#收集監控結果，儲存到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

將用例執行結果和監控結果都彙總到summary.txt裡 
生成的格式如下，方便後面生成html格式的報告

[[email protected] loadtest]# cat summary.txt 
/testcase/user/獲取使用者自己的資訊 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%

伺服器監控指令碼

#!/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
