This configuration interview allows you to run tests in two ways:

- Tests are executed on the same machine running the JT Harness harness, in another process, by means of the `Runtime.exec` Java API method. This is usually the most convenient way to run tests if your tests can be run in a JVM on this machine.
- Tests are executed on some other machine, by means of the JT Harness Agent. This method may be preferable if the test system cannot run the JT Harness harness or cannot start processes.
