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）
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
解析关键字
具体实现代码如下
