我将Chrome更新为版本58后，无法切换到相框。 这是我的代码：
driver.switchTo().frame(frameId);
尝试使用另外两个重载 frame（）方法（接受 index 和 WebElement ） - 同样的问题。
以下是例外：
org.openqa.selenium.NoSuchFrameException: no such frame: element is not a frame

对于Chrome 57,56及更早版本，一切正常。有什么想法吗？

iframe中的HTML是从我的扩展程序加载的。它在UI上很好地显示，工作正常，但是当我检查元素时 - 那里没有内容。刚刚查看了Chrome 57 - 我可以在那里看到内容。
所以这是一个问题，我理解为什么selenium会给我这个错误。
现在的问题是Google Chrome决定隐藏iframe的内容，以及如何使用selenium测试我的iframe。有趣的是，我可以看到从外部资源（而不是从扩展名）加载的另一个iframe的html。
