当我尝试运行此代码时，我收到org.openqa.selenium.StaleElementReferenceException：在缓存中找不到元素 - 也许页面自查找以来已更改 命令持续时间或超时：10.05秒。
基本上，我已经在类的开头声明了所有webelement变量，以减小代码的大小。但是当页面刷新时，StaleElementReferenceException即将到来。

答案 0 :(得分：0)
你已经给出了问题本身的答案，因为你说在页面刷新后出现异常，所以基本上，DOM上不存在该元素，可能是js刷新是一个原因。 您可以参考以下链接获取有关它的详细信息 http://www.seleniumhq.org/exceptions/stale_element_reference.jsp
