Load Agents


Visual Studio includes a new load agent product for achieving scaleable load generation. The Team Test Load Agent enables you to configure an arbitrary number of agents that will work together to generate load against a web server or web farm.


Key features include:


        Scale out load generation


        Efficient load generation (1000 users from a typical machine running a typical web test)


        IP Switching for testing web farms. Each agent can be configured to use a range of IP addresses. That way load is distributed appropriately when load testing a web farm.


        Favorable Per CPU licensing (no vUser licensing)


        Performance counters collected on Load Agents and machines under test.


        Data (performance data, perfmon counters, and logs) are rolled up and stored in central SQL Server for analysis


        Load Test Monitor enables monitoring a test in progress


        Run tests from VS or Command Line


        Deployment of test code, reverse deployment of logs/test results


        Parallel distributed functional test execution


        Run a large set of unit and functional tests at the same time


        Agent selection enables matrix testing


        Code Coverage


        Better quality of service: load tests are restarted if the test process exits due to a failure.


        Share test lab hardware with a team


        Multiple clients can submit test runs


        Controller queues runs and manages agents


        Platform for test tools


        Extensible architecture supports third party test types


        Team Foundation Server integration


        Reporting


        Work Item tracking


        Build Server


        Source Code Control


 


There are a couple of articles on our team blog that discuss the load agent:
