In the Web performance tests, the addition of Loops and Conditions enables developers to write more complex and intelligent tests against their applications. For load tests, the addition of 64-bit agents and controllers allows you to more effectively use the available hardware resources to generate load. Additionally, changes to the licensing of the load test agents and controllers gives you greater flexibility, making it easier -- and potentially cheaper -- to configure your load test rigs.
Web tests allow you to simulate a user performing a set of operations – typically a defined use case – on your ASP.NET Web application, and validate the responses to see if the application is working as expected. Once you have your Web tests defined, you can knit them together to create a load test to see how well your application performs under stress.
Create Some Web Tests:
Web tests are typically created using the Internet Explorer Web Testing toolbar, which records a human user clicking through a Web application. In the sample code for this article, our Visual Studio Test Project is called Com.Benday.WebTesting.WebTests. You can create a new Web test by right-clicking the project and choosing new Web Test (in Visual Studio 2010, Web Performance Test) from the Add menu. See the below picture.
When you add a new Web Test to your project, Visual Studio will open up Internet Explorer and you should see the Web Test Recorder panel in the browser. You can now go to a Web site and start using it just like you normally would and, as you go, you'll see your actions being recorded by the Web Test Recorder.

When you've finished performing the actions that you wanted to record, click the Stop on the Web Test Recorder toolbar and you'll be taken back to Visual Studio and you'll see your actions in a *.webtest file (Figure 2).
