1.基础层（Base / Driver & Web 封装）

文件：webbase.py

作用：
提供浏览器与元素操作的最小“积木”：打开页面、显式等待、找元素、点/输。所有页面对象继承它，避免在用例里写底层 Selenium 代码。

2.逻辑层（Page Object / 页面动作封装）

文件：homePage.py（继承 WebBase）

作用：
把“页面元素 + 页面动作”封装成类方法：页面逻辑（而不是业务流程）。测试/业务层只调用这些方法。

3.业务层（Test / 用例与业务流程编排）

文件：test_baidu_case.py（pytest 用例）

作用：
组合页面动作形成业务流程：例如“搜索”“跳转新闻页”。断言/数据驱动也在这一层。
