4 个答案:

答案 0 :(得分：1)

如果您有一个WebElement，然后源代码发生变化，然后您尝试读取或写入元素，就会发生这种情况。如果对页面进行了更改，则不能再使用该元素。在页面更改后，您应该尝试返回元素。例如，保存元素id，然后保存findElement(By.id(...))。

答案 1 :(得分：1)

如果您的页面/元素通过刷新或更新卸载，安全的方法是再次找到您的元素。

如果您正在使用Page Object设计模式，我认为获取StaleElementException并不容易，因为它使用动态代理，并且每个命令都有查找。如果您使用的是PageObject，并且在该字段上有@CacheLookup注释，请将其删除并重试。

答案 2 :(得分：0)

根据您提供的信息，Selenium似乎未能找到应该存在的元素。你能否将这个错误精确定位到页面上的单个元素？

看起来selenium正在尝试安排点击事件而无法安排。测试期间显示屏上有什么变化？

答案 3 :(得分：0)
