Distributing Load Test Runs Across Multiple Test Machines Using Test Controllers and Test Agents

Visual Studio Ultimate can use physical or virtual machines to generate simulated load for your app. These machines must be set up as a single test controller and one or more test agents. You can use the test controller and test agents to generate more load than a single computer can generate alone.

Don’t want to use your resources and set up your own machines to create this load? You can use cloud-based load testing to provide virtual machines in the cloud that generate the load of many users accessing your web site at the same time. All you need is a Visual Studio Online account. Learn more about this cloud-based load testing service that provides 15,000 free virtual user minutes of load testing every month.
