Question

我在C＃中使用NUnit和Selenium来构建一个包含在多个浏览器上运行多个测试用例的框架。在这种情况下，也支持Microsoft Edge。当我设置我的测试时，chrome和firefox正确运行但是edge会出现以下错误：

OpenQA.Selenium.WebDriverException：抛出了一个带有空响应的异常，向URL http://localhost:55992/session的远程WebDriver服务器发送HTTP请求。异常的状态是ReceiveFailure，消息是：基础连接已关闭：接收时发生意外错误。 ----＆GT; System.Net.WebException：基础连接已关闭：接收时发生意外错误。 ----＆GT; System.IO.IOException：无法从传输连接读取数据：远程主机强制关闭现有连接。 ----＆GT; System.Net.Sockets.SocketException：远程主机强制关闭现有连接 [2018。 06. 17. 17:08:22警告]在OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest（HttpRequestInfo requestInfo）在OpenQA.Selenium.Remote.HttpCommandExecutor.Execute（命令commandToExecute）在OpenQA.Selenium.Remote.DriverServiceCommandExecutor.Execute（命令commandToExecute）在OpenQA.Selenium.Remote.RemoteWebDriver.Execute（String driverCommandToExecute，Dictionary`2参数）在OpenQA.Selenium.Remote.RemoteWebDriver.StartSession（ICapabilities desiredCapabilities）在OpenQA.Selenium.Remote.RemoteWebDriver..ctor（ICommandExecutor commandExecutor，ICapabilities desiredCapabilities）在OpenQA.Selenium.Edge.EdgeDriver..ctor（EdgeOptions选项）在OpenQA.Selenium.Edge.EdgeDriver..ctor（）在SeleniumNUnit.Tests.WebDriverFactory.EdgeDriver（）中的C：\ SeleniumNUnit - Copy \ SeleniumNUnit.Tests \ Class1.cs：第70行在C：\ SeleniumNUnit中的SeleniumNUnit.Tests.WebDriverFactory.WebDriver（BrowserType类型） - Copy \ SeleniumNUnit.Tests \ Class1.cs：第50行在C：\ SeleniumNUnit中的SeleniumNUnit.Tests.WebDriverFactory..ctor（BrowserType类型） - Copy \ SeleniumNUnit.Tests \ Class1.cs：第24行在SeleniumNUnit.DemoTest..ctor（BrowserType浏览器）中的C：\ SeleniumNUnit - Copy \ SeleniumNUnit \ Class1.cs：第12行 --WebException 在System.Net.HttpWebRequest.GetResponse（）在OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest（HttpRequestInfo requestInfo） --IOException 在System.Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，Int32大小）在System.Net.PooledStream.Read（Byte []缓冲区，Int32偏移量，Int32大小）在System.Net.Connection.SyncRead（HttpWebRequest请求，布尔userRetrievedStream，布尔probeRead） --SocketException 在System.Net.Sockets.Socket.Receive（Byte []缓冲区，Int32偏移量，Int32大小，SocketFlags socketFlags）在System.Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，Int32大小）

我试图查找此特定错误，而我得到的最接近的是远程驱动程序尝试发送HTTP请求，在这种情况下失败。由于Chrome和FF运行正常，我不知道Edge出了什么问题。

我遇到了同样的问题，但后来我发现了这个问题：

Selenium.WebDriver.MicrosoftDriver v17.17134.0 crash when running the test

长话短说，请检查您的Windows版本。如果是17134版本，那么获取MicrosoftWebDriver 17134版本。但是，如果您使用的是16299.xxx，则必须使用16299版本的MicrosoftWebDriver。
