You can run the JT4Demo two different ways:

- On the same computer that runs the JavaTest harness (in a separate JVM) by means of the `Runtime.exec` Java API method.
- On another computer or device using a JavaTest Agent. The JavaTest Agent runs tests on a separate computer and communicates with the JavaTest harness over the network. Choose this answer if you cannot run your tests on the same computer that runs the JavaTest harness.
