How to run NUnit tests on multiple nodes using Selenium Grid

Hi,

 

I am configuring the Selenium Grid for Selenium C# project. I have to execute multiple test cases and set of nodes. I have configured hub and nodes. In Uri if I am passing IP and port of node then test cases are running on that node but on entering hub's IP and port below exception is occuring.

 

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities = DesiredCapabilities.Chrome();

capabilities.SetCapability(CapabilityType.BrowserName, "chrome");

capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));

driver = new RemoteWebDriver(new Uri("http://HUB IP:PORT/wd/hub"), capabilities);

Exception:“ at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse)

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.Remote.RemoteWebDriver..ctor(Uri remoteAddress, ICapabilities desiredCapabilities)

How I can run multiple test cases on different nodes in parallel?
