自动化脚本

在前述测试REST API的Test Plan的基础上，将Thread Group的线程数替换为变量。

保存此Test Plan，例如，把它另存为Automation1.jmx。

然后编写下面的.sh脚本。

> vi test.sh

#!/usr/bin/bash

echo "自动化压测开始"

export jmx_template="Automation1"
export suffix=".jmx"
export jmx_template_filename="${jmx_template}${suffix}"
export os_type=`uname`

# JMeter安装目录的位置
# export JMETER_HOME="/Users.../apache-jmeter-5.2.1"

# 清空nohup.out
cat /dev/null > nohup.out

# 强制杀掉JMeter进程
killJMeter()
{
    pid=`ps -ef|grep jmeter|grep java|grep ${jmx_filename}|awk '{print $2}'`
    echo "jmeter Id list :$pid"
    if [[ "$pid" = "" ]]
    then
      echo "no jmeter pid alive"
    else
      kill -9 $pid
    fi
}

# 压测并发数
thread_number_array=(100 1000 3000)
for num in "${thread_number_array[@]}"
do
    # 生成压测线程文件
    export jmx_filename="${jmx_template}_${num}${suffix}"
    export jtl_filename="test_${num}.jtl"

    rm -f ${jmx_filename} ${jtl_filename}

    cp ${jmx_template_filename} ${jmx_filename}
    echo "生成压测脚本 ${jmx_filename}"

    if [[ "${os_type}" == "Darwin" ]]; then
        sed -i "" "s/thread_nums/${num}/g" ${jmx_filename}
    else
        sed -i "s/thread_nums/${num}/g" ${jmx_filename}
    fi

    # JMeter静默压测并生成报告
    nohup ${JMETER_HOME}/bin/jmeter -n -t ${jmx_filename} -l ${jtl_filename} -e -f -o ./reports_${num} &
    sleep 20
    killJMeter
    rm -f ${jmx_filename}
done
echo "自动化压测结束"
