Python自动化测试系列[v1.0.0][BeautifulReport测试报告]

获取BeautifulReport模块

BeautifulReport 源码Clone地址为 BeautifulReport ，其中BeautifulReport.py和其template是我们需要的

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

自带HTML模板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

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')
