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 :

using System;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
using NUnit.Framework;
using Selenium;

namespace InvoiceTest
{
[TestFixture]
public class TestWeb
{
private ISelenium selenium;
private StringBuilder verificationErrors;

[SetUp]
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>
selenium.Start();
verificationErrors = new StringBuilder();
}

[TearDown]
public void TeardownTest()
{
try
{
selenium.Stop();
}
catch (Exception)
{
// Ignore errors if unable to close the browser
}
Console.WriteLine(verificationErrors.ToString());
Assert.AreEqual("", verificationErrors.ToString());
}

[Test]
public void FindTextAfterClickOnButton()
{

selenium.Open("/<strong>your application</strong>");
selenium.Focus("");
selenium.WindowMaximize();
selenium.Type("the textbox", "the text");
selenium.Click("button ");
selenium.WaitForPageToLoad("30000");
try
{
Assert.IsTrue(selenium.IsTextPresent("<strong>new text from your application</strong>"));
}
catch (AssertionException e)
{
verificationErrors.Append(e.Message);
Console.WriteLine(e.Message);
}
}

}
}
