Coverage Tests (Device Fundamentals)

The Device Fundamental Coverage tests monitor and report on the various I/O request packets (IRPs) that enter or leave a driver stack for specified devices. The data from the Coverage tests can help identify coverage weaknesses during driver test and verification.
