namespace SeleniumTest
{
    [TestFixture(typeof(FirefoxDriver))]
    [TestFixture(typeof(InternetExplorerDriver))]
    public class BlogTest<TWebDriver> where TWebDriver : IWebDriver, new()
    {
        private IWebDriver _driver;

        [Test]
        public void SearchResults_ShouldHaveCorrectPageTitle()
        {
            _driver = new TWebDriver();

            // Navigate
            _driver.Navigate().GoToUrl("http://www.deanhume.com");

            IWebElement searchBox = _driver.FindElement(By.Name("searchValue"));
            searchBox.SendKeys("moq");
            searchBox.Submit();

            Assert.AreEqual("Dean Hume - Search Results - moq", _driver.Title);
        }

        [TestFixtureTearDown]
        public void FixtureTearDown()
        {
            if (_driver != null) _driver.Close();
        }
    }
}

Good stuff, The problem with this approach is that the driver is created per each Test which is expensive. I created a base class and I was able to create the driver per Test case rather than creating it per single test.

I wonder if there is a way to create the driver and reuse it during all the execution, it would be faster.
