关键字驱动测试框架搭建(3)
关键字驱动的完整框架:
在Pycharm中创建一Python工程,其下再创建Util包,action包,config包,testScripts包,log目录,testData目录,exceptionPictures目录,具体内容如下:
Util包中存放封装的常用函数:

在框架目录创建RunTest.py,执行测试脚本:

#encoding=utf-8
from testScripts.TestSendMailWithAttachment import TestSendMailWithAttachment

if __name__ == "__main__":
    TestSendMailWithAttachment()

总结:

完整框架是参考别人的代码写的,最后虽然可以执行成功,但测试结果未成功写入Excel,以后再进行优化
