WDDM Handles - Invalid Param First Group
This automated test verifies that kernel-mode drivers are stable when they process handles that are invalid or of the incorrect type.
The test intercepts handles that the operating system kernel returns to the user-mode driver. It then modifies the handles. User-mode drivers can then generate invalid commands and handle lists that are passed to the kernel-mode driver. Kernel-mode drivers must not fail or hang during this test.
This topic applies to the following test jobs:
WDDM Handles - Invalid Param First Group
WDDM Handles - Invalid Param Second Group
WDDM Handles - Invalid Param Third Group
