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.

About the Coverage tests
The Device Fundamentals coverage tests are based upon the Driver Coverage Toolkit, which was previously available as stand-alone tool in the WDK. For information about how the coverage tests are implemented, see Driver Coverage Toolkit.
