基于Python组装jmx并调用JMeter实现压力测试

Posted in Python onNovember 03, 2020

JMeter可以通过os命令调用Python脚本，Python同样可以通过系统命令调用JMeter执行压测

Python调用JMeter

首先要安装JMeter，官方下载地址

解压并配置配置环境路径或建立软连，使得在命令输入jmeter便可以执行，如

unzip apache-jmeter-5.3.zip
mv apache-jmeter-5.3 /usr/loca/jmeter
ln -s /usr/local/jmeter/bin/jmeter /usr/bin/jmeter
ln -s /usr/local/jmeter/bin/jmeter-server /usr/bin/jmeter-server

打开JMeter并设计一个测试计划保存为testplan.jmx

使用Python调用JMeter压测并生成报告

Python中可以使用os.system()或supprocess.Popen()调用系统命令，前者实时显示在屏幕上，后者可以获取到屏幕输出信息。
使用Python调用JMeter运行及生成报告的命令如下。

import subprocess

jmx_file = 'testplan.jmx' # jmx文件路径
result_file = 'result.jtl' # 
log_file = 'run.log'
report_dir = 'report'

run_cmd = f'jmeter -n -t {jmx_file} -l {result_file} -j {log_file}' # 无界面运行JMeter压测命令
report_cmd = f'jmeter -g {result_file} -o {report_dir}' # 生成HTML报告命令

# 不需要获取屏幕输出是，可以使用os.system()
# os.system(run_cmd)
# os.system(report_cmd)

# 需要获取屏幕输出是，可以使用subprocess.Popen()
p1 = subprocess.Popen(run_cmd, shell=True, stdout=subprocess.PIPE)
print(p1.stdout.read().decode('utf-8'))
p2 = subprocess.Popen(report_cmd, shell=True, stdout=subprocess.PIPE)
print(p2.stdout.read().decode('utf-8'))

组装jmx

每一测试计划为一个jmx文件，jmx实际上是xml格式的，包含一些JMeter自定义的格式规范。
常用的组件有：

  • : 测试计划
  • : 线程组
  • : CSV数据文件
  • : HTTP请求
  • : HTTP请求头管理器
  • : Cookies管理器
  • : DNS缓存管理器
  • : 监听器(包括查看结果树、聚合报告等)
  • ： 响应断言
  • <io.github.ningyu.jmeter.plugin.dubbo.sample.DubboSample></io.github.ningyu.jmeter.plugin.dubbo.sample.DubboSample>: 三方Dubbo请求插件

Dubbo插件jmeter-plugins-dubbo下载链接

jmx中，如果一个组件有子组件，格式为

<ThreadGroup 组件基本属性>
   ...线程组配置
</ThreadGroup>
<hashTree>
   ...内部子组件
</hashTree>
···
如果不包含子组件，则后面接一个<hashTree/> 单标签直接结束，例如：
```xml
<CSVDataSet>
  ... CSV数据组件配置
</CSVDataSet>
<hashTree/>

详细的格式可以自己使用JMeter创建一个测试计划，使用文本文件打开jmx文件查看。

使用Python组装jmx文件的方式有两种，一种是固定模板的数据渲染，一种类似JMeter的逐个组件添加，第一种比较简单。
通过分析jmx文件中的变量，我们使用jinja2模板语法，将其中的变量进行参数化，对需要判断和循环的变量设置if和for循环。

Jinja2中文文档

假设我们的测试计划结构为：

测试计划
  DNS缓存管理器
  Cookies管理器
  CSV文件(多个)
  ...
  聚合报告
  线程组(多个)
    CSV文件(多个)
    HTTP请求(或Dubbo请求)
      HTTP请求头管理器
      CSV文件(多个)
      响应断言
      察看结果树

将jmx中的关键数据抽取并组合，我使用的完整数据格式如下：

组装出类似data.yaml格式的数据，并使用jinja2渲染模板即可得到完整的jmx文件

pip install pyyaml jinja2

import yaml
import jinja2

# 组装或读取数据
with open('data.yaml', encoding='utf-8') as f:
  data = yaml.safe_load(f)

 # 读取模板
with open('tpl.xml', encoding='utf-8') as f:
  tpl = f.read()

# 渲染模板生成jmx
jmx = jinja2.Template(tpl).render(data)
with open(jmx_file, 'w', encoding='utf-8') as f:
  f.write(jmx)

后计

在实际项目中，还涉及数据文件的拷贝，节点环境的部署，脚本的分发，报告的下载等等，可以使用paramiko或者fabric或ansible完成，压测节点数据分发的服务管理。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持三水点靠木。
