Use this mode for testing if you want to simultaneously run other applications in addition to this software on the system. The goal of this mode is to validate the hardware without having significant impact on other applications running on the system. In this mode, the tests would not stress the system, and to provide coverage they might have to run for longer periods of time. If there are any latent faults in the system hardware, the tests in this level will try to stimulate those faults before the application is impacted by the fault. When the test stimulates the fault, the OS detects the fault and takes appropriate action.
The test characteristics in this mode are as follows:
Nonintrusive: The tests running in this mode do not intrude on the applications that are running on the system. Nonintrusive mode does not change any system configuration that can have an effect on the applications.
Data Safe: The tests running in this mode do not cause any kind of data corruption.
Test Time: The time of completion for these tests could vary from milliseconds to days. There is no restriction on the amount of time.
Resource Usage: The resource usage is designed so that the test does not have any distinguishable effect on the applications that are running on the system. The goal is to use as few resources as possible for a given instance of time.
