Python组装jmx并调用JMeter实现压力测试

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。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

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

1 2 3 4 5 6 7 8 9 10 11 12 13

<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：

1 2 3 4 5 6 7 8 9 10 11 12 13

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：

data.yaml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

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。
