screen recording in webdriver with C#

Last couple of days, I am searching screen recording by using webdriver with C# similar to “Monte Media Library” in java and finally I got the solution. Here, I am posting my finding so that it can help others.

For screen capturing Microsoft provide” Microsoft Expression Encoder 4” which can be download and install from link “http://www.microsoft.com/en-in/download/confirmation.aspx?id=27870”

Default installation directory is “C:\Program Files\Microsoft Expression”.

Steps to create and run webdriver test.

1. You need to make sure that you have setup all required dll for of webdriver and Nunit.
2. Download and install”Microsoft Expression Encoder 4” from above mentioned url.
3. Add “Microsoft.Expression.Encoder.dll” from “C:\Program Files\Microsoft Expression\Encoder 4\SDK” folder to your webdriver project.
4. You need to add import below class in your test.

using Microsoft.Expression.Encoder.ScreenCapture;

5. Create object of ScreenCaptureJob in your test.

ScreenCaptureJob scj = new ScreenCaptureJob();

6. Sample code for screen capturing

using NUnit.Framework;

using OpenQA.Selenium;

using Microsoft.Expression.Encoder.ScreenCapture;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.Support.UI;

namespace ScreenRecording.TestScript

{

   [TestFixture]

   public class ScreenRecording

   {

       IWebDriver driver;

       ScreenCaptureJob scj;

       [SetUp]

       public void TestSetup()

       {

           // Create a instance of ScreenCaptureJob

           scj = new ScreenCaptureJob();

           // Specify the path & file name in which you want to save         

           scj.OutputScreenCaptureFileName = @"C:\ScreenRecording.wmv";

           // Start the Screen Capture Job

           scj.Start();

           driver = new FirefoxDriver();

       }

       [TestCase]

       public void TestGoogleSearch()

       {

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

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

           query.SendKeys("testing");

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

       }

       [TearDown]

       public void TestCleanUp()

       {

           //Close the Browser

           driver.Close();

           //Stop the Screen Captureing

           scj.Stop();

       }

   }

      

}

7. Set file name and path in “scj.OutputScreenCaptureFileName = @"C:\ScreenRecording.wmv"; “
8. Build and run above code using Nunit , after execution a video file will generate at mentioned location and file
