Python&Selenium&Unittest&BeautifuReport 自动化测试并生成HTML自动化测试报告

一、摘要

本篇博文将介绍如何借助BeautifulReport和HTML模版，生成HTML测试报告的BeautifulReport 源码Clone地址为 https://github.com/TesterlifeRaymond/BeautifulReport，其中

BeautifulReport.py和其template是我们需要的关键。

二、BeautifulReport

如下代码是BeautifulReport.py的源码，其中几个注释的地方需要注意，将其集成进自己的自动化框架时需要做相应的修改

三、template

template文件是和BeautifulReport.py一起使用的，他将unittest的测试结果按照template的样式转换成HTML格式的报告

四、调用BeautifulReport

import unittest
from Run.BeautifulReport import BeautifulReport

if __name__ == '__main__':
test_suite = unittest.defaultTestLoader.discover('TestScripts', pattern='test*.py')
result = BeautifulReport(test_suite)
result.report(filename='测试报告', description='测试报告', log_path='D:\\Programs\\Python\\PythonUnittest\\Reports')

 五、报告样式
