PO模式

Page Object Model

测试页面和测试脚本分离，即页面封装成类，供测试脚本进行调用。
也就是说，脚本只需要负责关心流程，具体操作某个元素的步骤封装在页面对应的类的方法中

优缺点

优点
1.提高测试用例的可读性;
2.减少了代码的重复;
3.提高测试用例的可维护性，特别是针对UI频繁变动的项目;
缺点
结构复杂: 基于流程做了模块化的拆分。

项目需求

- 更多-移动网络-首选网络类型-点击2G
- 更多-移动网络-首选网络类型-点击3G
- 显示-搜索按钮-输入hello-点击返回

多文件区分测试用例

需求

- 使用多个文件来区分不同的测试页面

好处

-修改不同的功能找对应的文件即可

步骤

1. 在scripts下新建test_network.py文件
2. 在scripts下新建test_dispaly.py文件
3. 移动不同的功能代码到对应的文件
4. 移除原有的test_setting.py文件

2. 新建network_page.py文件
3. 新建display_page.py文件
4. 调用init函数传入driver
5. init进入需要测试的页面
6. page中新建“小动作”函数
7. 移动代码
8. 修改测试文件中的代码

抽取查找元素的特征

需求

- 将元素的特征放在函数之上

好处

- 若特征改了，流程不变，可以直接在上面修改

步骤

1. 将find_element_by_xxx改为find_element
2. 将方式和具体特征向上移动
一切目的都是为了代码简单易于维护。
