自动化工具 Python 调 Jmeter 执行参数化 jmx 脚本

烦透了jmeter输入如下鬼命令:

  Jmeter -n -t {tmpjmxfile} -l {csvfilename} -e -o {htmlreportpath}

尤其是{htmlreportpath}这个文件夹路径,没有这个文件夹又不会自动创建,有的话又必须为空。经常要给文件夹、文件命名,而且命名又没什么规范,乱七八糟的。

  于是想着,即便是用python帮我创建文件夹,帮我生成命令,也是好的。

精益求精,做着做着,就会想着,干脆把命令也给执行了,于是就有这样的产出。
使用场景:

    1.需要不断的运行性能测试脚本,摸底,取数。 如线程数、循环次数。

    2.需要等待较长时间的

 

 

执行此脚本的条件是,在一个目录下,只能有一个jmx后缀文件。当然可以有参数化文件,拷贝execjmeter.py和runafter.py文件到该目录下。简单例子如下:

 

 

话不多说,直接来段代码,代码仍需不断改进:

  python版本=3.6.1,这段代码命名为execjmeter.py

执行代码后,将会生成有规律的文件。文件列表如下:

 

 

由于持续的多次执行,将会产生很多文件。文件太多,会让人感觉很错乱,看起来累人。比如说每次执行的T线程数XL循环数场景后,都会产生很多文件。文件多了,查看html报表需要进入逐个目录打开index.html文件查看。于是又想到再做一个html>表格页面。方便一览查看。便再做了一个py脚本,命名为runafter.py 。当然这还不是最好的,忘记了最初的想要的结果是什么了吗?

import os
from os.path import join


currpath = os.path.dirname(os.path.realpath(__file__))
run_time_list = []
scene_name_list = []
jmxfile_name_list = []
csvfile_list = []
htmlreport_list = []


for root, dirs, files in os.walk(currpath):
    for name in files:
        if '.jmx' in name and '-' in name and 'XL' in name:
            name_split_list = name.split('-')
            run_time_list.append(name_split_list[0])
            scene_name_list.append(name_split_list[-1].replace('.jmx', ''))
            jmxfile_path = join(root, name).replace('\\', '/')
            jmxfile_link = f'<a href="file:///{jmxfile_path}" target="_blank">{name}</a>'
            jmxfile_name_list.append(jmxfile_link)
            csvfile_name = name_split_list[0]+'-result.csv'
            csvfile_path = join(root, csvfile_name).replace('\\', '/')
            csvfile_link = f'<a href="file:///{csvfile_path}" target="_blank">{csvfile_name}</a>'
            csvfile_list.append(csvfile_link)
            htmlfile_tail = '\\' + name_split_list[0] + '-htmlreport\\index.html'
            htmlfile_path = currpath + htmlfile_tail
            htmlfile_path = htmlfile_path.replace('\\', '/')
            htmlfile_link = f'<a href="file:///{htmlfile_path}" target="_blank">查看</a>'
            htmlreport_list.append(htmlfile_link)

result = [run_time_list, scene_name_list, jmxfile_name_list, csvfile_list,
          htmlreport_list]
title = ['执行时间', '场景名', 'jmx文件', '响应结果', '报告详情']

th_str = '<tr>'
for x in title:
    th_str = th_str + '<th>' + x + '</th>'
else:
    th_str = th_str + '</tr>'

td_str = ''
for index, item in enumerate(run_time_list):
    td_str = td_str + '<tr>'
    for x in result:
        td_str = td_str + '<td>' + x[index] + '</td>'
    td_str = td_str + '</tr>'
table_str = f'<table border="1">{th_str}{td_str}</table>'
html_str = f'<!DOCTYPE html><html lang="en"><body><center>{table_str}</center></body></html>'
with open('SummaryReport.htm', 'w', encoding='utf-8') as file:
    file.writelines(html_str)
 

执行完该脚本后,会生成一个SummaryReport.htm的html表格页面。效果如下:

 

 

期间,碰到的坑如下,如命令行执行 Jmeter -n -t {tmpjmxfile} -l {csvfilename} -e -o {htmlreportpath} 命令,由于本渣的 JMETER_Home =D:\Program Files\apache-jmeter\bin,就因为这个就碰到两个坑

  一、路径包含空格,识别不了可执行的程序命令

解决办法:命令要用“”引号包起来

  二、执行命令识别不了Jmeter,即便将JMETER_Home加入path,或者用cd 命令进入JMETER_Home也无效。

  解决办法:控制台用cmd命令执行。如"cmd.exe /c {JMETER_Home} -n -t {tmpjmxfile} -l {csvfilename} -e -o {htmlreportpath}"
