Python&Selenium 关键字驱动测试框架之数据文件解析

摘要:在关键字驱动测试框架中,除了PO模式以及一些常规Action的封装外,一个很重要的内容就是读写EXCEL,在团队中如何让不会写代码的人也可以进行自动化测试? 我们可以将自动化测试用例按一定的规格写到EXCEL中去(如下图所示)

Python&Selenium 关键字驱动测试框架之数据文件解析

然后通过代码实现对具备这种规格的EXCEL进行解析,让你的代码获取EXCEL中的步骤,关键字,页面元素定位,操作方式,最后在写入执行结果,附上异常截图即可;团队中不会写代码的人居多,改改Excel执行也可以实现自动化测试

此处在初始化类的时候定义了两个颜色放进字典中,之后会当做参数传给写EXCEL的函数,当测试用例执行通过 用绿色字体标注pass,当执行失败的时候用红色字体标注failed

具体实现代码如下

那么我们的测试数据除了放在Excel中,还可以存储在XML里,然后关键字驱动框架中提供解析XML的API
