Question

我有一个非常简单的脚本作为冒烟测试。

该脚本执行以下操作：

注册驱动程序
驱动程序导航至“https://www.google.co.uk/”
驱动程序退出

脚本：

require 'selenium-webdriver'
driver = Selenium::WebDriver.for(:edge)
driver.navigate.to("https://www.google.co.uk/")
driver.quit

当我运行此程序时，驱动程序打开Edge，导航到google并且MicrosoftWebDriver在'quit'方法之前停止，导致ruby引发错误。

Bellow是控制台的输出：

我已经尝试解决此问题：

我已禁用防火墙并关闭了防病毒软件
尝试了不同版本的MicrosoftWebDriver
尝试了不同版本的SeleniumDriver

对我而言，这看起来像MS特定的问题，因为它之前有效（我现在遇到同样的问题），但是在Windows更新后突然出现了这条消息。 According to MS一个可能的解决方案是使用Fiddler4（http://fiddler2.com/r/?GetFiddler4Beta）内置的WinConfig工具或CheckNetIsolation工具来免除Edge

要为Edge启用环回，请使用以下命令：

CheckNetIsolation LoopbackExempt -a -n="Microsoft.MicrosoftEdge_8wekyb3d8bbwe"

要禁用Edge的环回，请使用此命令：

CheckNetIsolation.exe LoopbackExempt –d –n="Microsoft.MicrosoftEdge_8wekyb3d8bbwe"

出于某些原因，我的本地机器尚未解决问题。然后经过一些调试帮助，他们给了我一个提示，它可能与防火墙有关。所以我关闭了Windows防火墙并再次尝试。问题解决了。我重新打开了Windows防火墙，奇怪的是问题没有恢复。

MicrosoftWebDriver在启动后不久就停止工作
