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
