Based on how you configure SunVTS, the test session runs in one of the following test modes:
Connection test mode--provides a low-stress, quick testing of the availability and connectivity of selected devices. These tests are non-intrusive, meaning they release the devices after a quick test, and they do not place a heavy load on system activity.
Functional test mode--provides robust testing of your system and devices. It uses your system resources for thorough testing and it assumes that no other applications are running.
Auto Config test mode--simplifies the SunVTS configuration process by automatically assigning a predetermined set of test options.
