Run Selenium Tests Behind The Proxy

If your system is behind a proxy or protected by a firewall, you will not be able to run the Selenium test scripts directly on the LambdaTest Selenium grid. You need to define your proxy settings so that the connection goes through as usual.

This documentation will help you run your Selenium test behind a proxy server.

How To Define Proxy Settings in Selenium C#?​

You can define proxy programmatically by adding the below snippet in your code.

HttpCommandExecutor commandExecutor = new HttpCommandExecutor(new Uri("https://username:accesskey@hub.lambdatest.com/"), TimeSpan.FromSeconds(60));
WebProxy myproxy = new WebProxy("proxy_host:proxy_port", false);
IWebDriver driver;

Below is the NUnit code that shows the insertion of the above code snippet to define proxy settings.

using System;
using System.Drawing.Text;
using System.Threading;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Remote;
using NUnit.Framework;
using System.Net;
namespace TestSelenium3
{
    public class Program
    {
        static void setProxy()
        {
            /* HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create("http://3.86.55.62:8888");
             // Obtain the 'Proxy' of the  Default browser.  
             IWebProxy proxy = myWebRequest.Proxy;
             // Print the Proxy Url to the console.
             if (proxy != null)
             {
                 Console.WriteLine("Proxy: {0}", proxy.GetProxy(myWebRequest.RequestUri));
             }
             else
             {
                 Console.WriteLine("Proxy is null; no proxy will be used");
             }
             */
        }
        public static void Main(String[] args)
        {
            // Init
            setProxy();
            HttpCommandExecutor commandExecutor = new HttpCommandExecutor(new Uri("https://username:accesskey@hub.lambdatest.com/"), TimeSpan.FromSeconds(60));
            commandExecutor.Proxy = new WebProxy("proxy_host:proxy_port", false);
            IWebDriver driver;
            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.SetCapability("build", "your build name");
            capabilities.SetCapability("name", "your test name");
            capabilities.SetCapability("platform", "Windows 10");
            capabilities.SetCapability("browserName", "Chrome");
            capabilities.SetCapability("version", "89.0");
            driver = new RemoteWebDriver(commandExecutor, capabilities);
            
            Console.WriteLine("----------------------------" + capabilities + "#####################################");
            try
            {
                /*
                                driver = new RemoteWebDriver(new Uri("https://username:accesskey@hub.lambdatest.com/"), capability);
                                    Console.WriteLine("----------------------------" + driver + "#####################################");
                */
                driver.Navigate().GoToUrl("https://www.google.com");
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                Thread.Sleep(500000);
            }
        }
    }
}

Execute the above NUnit test scripts, and you’ll be able to run your Selenium tests directly on the LambdaTest Selenium grid behind the proxy server.
