Selenium and testing WebInterfaces

On some cases you need to test the whole web interface. Why ? Suppose you have some Ajax call. You can test the call on server, but how do you ensure that user experience is OK ?

There are several testing projects for Web – for example selenium and Watin

I will show how to test with Selenium + NUNIT

  1. Download selenium from http://seleniumhq.org/ and download Firefox add-on from http://seleniumhq.org/projects/ide/
  2. Start selenium with java -jar selenium-server.jar
  3. Record the test with FF.
  4. Create a usual NUnit test project and add a reference to ThoughtWorks.Selenium.Core.dll
  5. The code can be like this :
  6. using System;
    using System.Text;
    using System.Text.RegularExpressions;
    using System.Threading;
    using NUnit.Framework;
    using Selenium;
    namespace InvoiceTest
    public class TestWeb
    private ISelenium selenium;
    private StringBuilder verificationErrors;
    public void SetupTest()
    //java -jar selenium-server.jar
    //selenium = new DefaultSelenium("localhost", 4444, @"*firefox d:\Program Files\Mozilla Firefox\firefox.exe","<a href="http://localhost/&quot;);">http://localhost/");</a>
    selenium = new DefaultSelenium("localhost", 4444, @"*iexplore", "<a href="http://localhost/&quot;);">http://localhost/");</a>
    //selenium = new DefaultSelenium("localhost", 4444, @"*iexploreproxy", "<a href="http://localhost/&quot;);">http://localhost/");</a>
    verificationErrors = new StringBuilder();
    public void TeardownTest()
    catch (Exception)
    // Ignore errors if unable to close the browser
    Assert.AreEqual("", verificationErrors.ToString());
    public void FindTextAfterClickOnButton()
    selenium.Open("/<strong>your application</strong>");
    selenium.Type("the textbox", "the text");
    selenium.Click("button ");
    Assert.IsTrue(selenium.IsTextPresent("<strong>new text from your application</strong>"));
    catch (AssertionException e)
