Team Test Rig

Visual Studio 2005

Several test types, including unit, Web, load, and manual tests as well as the measurement of code coverage, are integrated into Visual Studio. Team Edition for Testers enables Visual Studio Team System users to run tests on remote computers, called a rig. A rig provides distributed, automated test execution. A Team Edition for Testers rig is made up of a test controller and one or more agents. One test controller can coordinate the execution of several test runs on computers which have the test agent installed.

The most common use of a rig is to scale load generation. For example, if you want to run a load test simulating 10,000 users, you can set up a single controller and five agent computers to emulate this. You can also run a large set of functional tests on the agent computers. The tests will run in parallel so you can reduce the amount of time it takes to execute all the tests.

Team Test Rig Services and Applications

The Team Edition for Testers controller hosts the test execution files necessary for Team Edition for Testers to run tests on Team Edition for Testers agent computers. The following services and applications run on the Team Edition for Testers controller:

  • Visual Studio Team Test Controller Service (QTController.exe)   This service communicates with the test agents and runs under the user context given at the time of installation. The user account specified must have permission to read performance counters on the test agent computers.

The following services and applications run on the Team Edition for Testers agent:

  • Visual Studio Team Test Agent Service (QTAgentService.exe)   This service communicates with the test controller and starts the agent processes on the computer where the tests are actually run. The service runs under the user context given at the time of installation.

  • Visual Studio Team Test Agent (QTAgent.exe)   Tests run in this process. The process runs under the user context given at time of installation.

Team Test Rig Requirements

The number of test rigs in your deployment and scope of your tests affect the hardware and software needed for the test controllers and agents in your environment. For more information about test rig hardware requirements, see Team Test Rig Requirements for Team Foundation Server.
