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.
