UI自动化之混合框架

什么是混合框架,混合框架就是将数据驱动与关键字驱动结合在一起,主要用来回归业务主流程,将核心流程串联起来。

上一篇我们写到了关键字驱动框架,关键字驱动框架是针对一个业务场景的单条测试用例的。

我们以163邮箱的登录到创建联系人这个流程为例,来看看混合框架是怎样的。

首先准备一个存放测试用例和数据的excel文件,文件内容如下:

测试用例的sheet页:case

mock表示这条测试用例我们需要用到的框架模型,key表示关键字,data表示数据

step_sheet表示这条用例我们需要用到的关键字驱动的sheet页名称

data_sheet表示这条用例我们需要用到的数据驱动的sheet页名称

add_person_step页:添加联系人的步骤

add_person_data页:添加联系人所需要用到的数据

excel的准备工作就完成了,接下来看代码:

首先是项目目录:只写了简单的几个目录,其他的目录在pageobject三层架构中写过,可以参考,都是一样的。

    except Exception as e:
        raise e

最后执行test_login_add_send.py文件,即实现了混合框架。
