  • You can testing the application using Visual Studio Using Visual Studio 2013, you can create, manage, and run web performance tests and load tests. To load test your app with on-premises resources or using cloud-based load testing, you first create web performance tests. These tests are used in your load tests to simulate multiple users performing actions in your app at the same time.
    You can use cloud-based load testing service which allows you to run your tests across multiple virtual machines in the cloud. You can also use an on-premises test controllers and test agents. In the full version of Visual Studio Ultimate, the number of virtual users is unlimited. However, if you need to emulate thousands of users, use test controller and test agent machines. In Visual Studio Ultimate Trial version, the virtual user count is limited to 250.
