篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了HttpRunner二次开发UI自动化框架相关的知识，希望对你有一定的参考价值。

在这里插入图片描述
基于HttpRunner接口自动化开源框架二次开发，下阶段更新UI自动化平台前端页面

Ui自动化应具备哪些功能呢？

Po模式，全称PageObject（页面对象）；UI自动化PO模式应把一个页面分为三层，对象库层、操作层、业务层。（这里只实现操作层）业务层可在debugtalk中拓展

收集每个test运行日志
页面报错截图
WebDriver、BasePage可全局调用
BrowserDriver配置
继承HttpRunner所有特性
先实现以上几个功能，有需求后面再继续扩展

重新封装runner. _run_test方法
