Using the InternetExplorerDriver for WebDriver

Are you getting this error when trying to use the InternetExplorerDriver for WebDriver (Selenium 2.0)?

System.InvalidOperationException

"Unexpected error launching Internet Explorer. Protected Mode must be set to the same value (enabled or disabled) for all zones. (NoSuchDriver)"

Don't worry, it's easier to fix than it sounds: Simply go into your Internet Options of Internet Explorer, select the Security tab, and all four zones to have the same Protected Mode value (either all on or all off). That's it!

Sample Code

using NUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.IE;

namespace WebDriverTests

{

    public abstract class WebDriverTestBase

    {

        public IWebDriver WebDriver { get; set; }

        [TestFixtureSetUp]

        public void TestFixtureSetUp()

        {

            WebDriver = new InternetExplorerDriver();

        }

        [TestFixtureTearDown]

        public void TestFixtureTearDown()

        {

            if (WebDriver != null)

            {

                WebDriver.Close();

                WebDriver.Dispose();

            }

        }

        [SetUp]

        public void SetUp()

        {

            WebDriver.Url = "about:blank";

        }

    }

    [TestFixture]

    public class GoogleTests : WebDriverTestBase

    {

        [Test]

        public void SearchForTom()

        {

            WebDriver.Url = "http://www.google.com/";

            IWebElement searchBox = WebDriver

                .FindElement(By.Id("lst-ib"));

            searchBox.SendKeys("Tom DuPont");

            searchBox.Submit();

            IWebElement firstResult = WebDriver

                .FindElement(By.CssSelector("#search cite"));

            Assert.AreEqual("www.tomdupont.net/", firstResult.Text);

        }

    }

}

Enjoy,
Tom
