Run Selenium tests in multiple browsers one after another from C# NUnit

Question

I'm looking for the recommended/nicest way to make Selenium tests execute in several browsers one after another. The website I'm testing isn't big, so I don't need a parallel solution yet.

I have the usual test set-up methods with  [SetUp], [TearDown], and [Test]. The SetUp one, of course, instantiates a new ISelenium object with whatever browser I want to test with.

So what I want to do is programmatically say: this test will be run on Chrome, IE, and Firefox in sequence. How do I do that?

EDIT:

This might help a bit. We're using CruiseControl.NET to start the NUnit tests after a successful build. Is there any way to pass a parameter to the NUnit executable, and then use that parameter in the test? This way we could have NUnit run several times with different browser parameters.

Answer 1

NUnit 2.5+ now supports Generic Test Fixtures which make testing in multiple browsers very straightforward.

http://www.nunit.org/index.php?p=testFixture&r=2.5

Running the following example will execute the GoogleTest twice, once in Firefox and once in IE.

using NUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.IE;

using System.Threading;

namespace SeleniumTests

{

   [TestFixture(typeof(FirefoxDriver))]

   [TestFixture(typeof(InternetExplorerDriver))]

   public class TestWithMultipleBrowsers<TWebDriver> where TWebDriver : IWebDriver, new()

   {

       private IWebDriver driver;

       [SetUp]

       public void CreateDriver () {

           this.driver = new TWebDriver();

       }

       [Test]

       public void GoogleTest() {

           driver.Navigate().GoToUrl("http://www.google.com/");

           IWebElement query = driver.FindElement(By.Name("q"));

           query.SendKeys("Bread" + Keys.Enter);

           Thread.Sleep(2000);

           Assert.AreEqual("bread - Google Search", driver.Title);

           driver.Quit();

       }}}
