思考:我们进行自动化测试时,如果把代码都写在一个脚本中,代码的可读性会变差,且后期代码维护也麻烦,最好的想法就是测试对象和测试用例可以分离,可以很快定位问题,代码可读性高,也比较容易理解。这里推荐大家在自动化框架中加入PO模型思想,那什么是PO模型呢?
所谓的PO就是page object,通俗解释一下就是每个页面当成一个对象,给这些页面写一个类,主要就是完成元素定位和业务操作;至于测试脚本要和ta区别开来,需要什么去这些页面类去调用即可。
上面流程图意思就是测试用例类调用不同的页面类,页面类调用公共基类,基类里面封装定义定位页面元素和基本业务操作方法。
BasePage.py(页面基类脚本)
