No connection could be made because the target machine actively refused it(selenium)

Question

I have extracted the following code from selenium IDE.(c# remote control)

using System; using System.Text; using System.Text.RegularExpressions; using System.Threading; using NUnit.Framework; using Selenium;  namespace SeleniumTests { [TestFixture] public class MyFirstVCTest {     private ISelenium selenium;     private StringBuilder verificationErrors;      [Test]     public void TheNewTest()     {         selenium.Open("/");     }       [SetUp]     public void SetupTest()     {         selenium = new DefaultSelenium("localhost", 4444, "*chrome","http://demo.volunteercampaigns.com/");         selenium.Start();         verificationErrors = new StringBuilder();     }      [TearDown]     public void TeardownTest()     {         try         {             selenium.Stop();         }         catch (Exception)         {             // Ignore errors if unable to close the browser         }         Assert.AreEqual("", verificationErrors.ToString());     }      [Test]     public void TheMyFirstVCTest()     {         selenium.Open("/?AspxAutoDetectCookieSupport=1");         selenium.Click("link=Login");         selenium.WaitForPageToLoad("30000");         selenium.Type("id=ctl00_ContentPlaceHolder1_txtEmailAddress", "[email protected]");         selenium.Type("id=ctl00_ContentPlaceHolder1_txtPassword", "orbs123");         selenium.Click("id=ctl00_ContentPlaceHolder1_btnlogin");         selenium.WaitForPageToLoad("30000");         selenium.Click("id=ctl00_lblUserName");         selenium.Click("id=ctl00_lnkSignOut");         selenium.WaitForPageToLoad("30000");     } } } 

i created a webform and added a button there.

in button click event i wrote this code

SeleniumTests.MyFirstVCTest m = new SeleniumTests.MyFirstVCTest();     m.SetupTest();     m.TheMyFirstVCTest();     m.TeardownTest(); 

i included all .dll files. its running fine(no errors and warnings).

but after clicking button i am getting the following error

No connection could be made because the target machine actively refused it 127.0.0.1:4444 

what should i do??

thanks in advance..

Answer 1

"...the target machine actively refused it" means the server could be reached and responded within the timeout, but the specified port wasn't open. This can have several reasons, e.g. a local firewall blocking the connection. Are you sure the server is listening on the right IP/port?

To add more clarity for the readers: Start selenium server using the followings basic steps:

• Download selenium -server standalone from official selenium download page.
  
  • Open command prompt.
  • Navigate to the folder using "Cd ".
  • Add this command: "java - jar ".
  • Hit enter.
  • Selenium server will be started.
