问题描述
所以我正在IE11中自动化一个Web应用程序(政府签约三声加油！)，我正在按照Selenium Wiki上的说明进行配置，因为我们有许多奇怪而怪异的行为.我现在处于此步骤，它说，我已经添加了一个注册表项，以帮助维持驱动程序和浏览器之间的连接:
So I am automating a web application in IE11 (Three cheers for government contracting!) and I am following the instructions on the Selenium Wiki to configure the thing because we have had a bunch of weird and wonky behavior. I am at this step here and well, it says that I have add a registry key to help maintain a connection to between the driver and the browser:
但这并不能真正解释为什么?如果您没有添加此密钥，怎么了? 维护IE实例和Webdriver之间的连接"一词可能意味着很多不同的事情.
But it doesn't really explain why? What goes wrong when you don't have this key added? The words "Maintain connection between an instance of IE and the webdriver" can mean a lot of different things.
我们遇到的问题在很大程度上与Selenium方法有关，例如.click()无法正常工作或无法在页面上单击以获得一些有趣的参考点.我们还遇到了一些奇怪的滚动问题，当元素在屏幕外时，它无法通过测试，这很奇怪，因为它应该读取DOM，但是我离题了.
The problems we are experiencing deal largely with Selenium Methods like .click() not working or not clicking on the page for those interesting in a point of reference. We are also having some weird scrolling issues where it fails a test when the element is juuuuust off-screen, which is weird because it should be reading the DOM, but I digress.
推荐答案
您看对了.根据 必需的配置 InternetExplorerDriver明确提到:
You saw it right. As per the documentation in the Required Configuration section of InternetExplorerDriver it is clearly mentioned:
仅对于 IE 11 ，您将需要在目标计算机上设置注册表项，以便驱动程序可以维持与其创建的Internet Explorer实例的连接.
For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates.

对于32位Windows安装，您必须在注册表编辑器中检查的密钥为:
For 32-bit Windows installations, the key you must examine in the registry editor is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE.
对于64位Windows安装，密钥为:
For 64-bit Windows installations, the key is:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE.
注意 FEATURE_BFCACHE 子项可能存在也可能不存在，如果不存在则应创建.重要说明:在此注册表项内，创建一个名为iexplore.exe的DWORD值，其值为0.
Note The FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.
