基于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。
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}' # * 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
: * (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。
