But users do not typically perform the same actions again and again. In this video we see how to extend and customize our automated Web tests to more accurately reflect the way a user would interact with the application. We learn how to create custom extraction rules to pull data from a Web control that the default extraction rules may not support, and how to add C# or Visual Basic-coded Web tests to add functionality such as looping, logic, and accessing external data.
