how to set up edgedriver correctly? getting the following error

Question

I'm using NUnit and Selenium in C# to build a framework which contains running multiple testcases on several browsers. Microsoft Edge is also supported in this case. When I set up my tests chrome and firefox run correctly but edge gives the following error:

OpenQA.Selenium.WebDriverException : A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:55992/session. The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive. ----> System.Net.WebException : The underlying connection was closed: An unexpected error occurred on a receive. ----> System.IO.IOException : Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ----> System.Net.Sockets.SocketException : An existing connection was forcibly closed by the remote host [2018. 06. 17. 17:08:22 Warning] at OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest(HttpRequestInfo requestInfo) at OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.DriverServiceCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities) at OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities) at OpenQA.Selenium.Edge.EdgeDriver..ctor(EdgeOptions options) at OpenQA.Selenium.Edge.EdgeDriver..ctor() at SeleniumNUnit.Tests.WebDriverFactory.EdgeDriver() in C:\SeleniumNUnit - Copy\SeleniumNUnit.Tests\Class1.cs:line 70 at SeleniumNUnit.Tests.WebDriverFactory.WebDriver(BrowserType type) in C:\SeleniumNUnit - Copy\SeleniumNUnit.Tests\Class1.cs:line 50 at SeleniumNUnit.Tests.WebDriverFactory..ctor(BrowserType type) in C:\SeleniumNUnit - Copy\SeleniumNUnit.Tests\Class1.cs:line 24 at SeleniumNUnit.DemoTest..ctor(BrowserType browser) in C:\SeleniumNUnit - Copy\SeleniumNUnit\Class1.cs:line 12 --WebException at System.Net.HttpWebRequest.GetResponse() at OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest(HttpRequestInfo requestInfo) --IOException at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --SocketException at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

I have tried to look up this specific error and the closest I got was that remote driver tries to send an HTTP request which in this case fails. Since Chrome and FF runs correctly I have no idea what goes wrong with Edge.

Answer 1

I was facing the same problem, but then I found this:

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

Long story short, check your Windows version. If it is the 17134 version, so get the MicrosoftWebDriver 17134 version. However, if you are on 16299.xxx, then you have to use the 16299 version of MicrosoftWebDriver.
