Currently, we have a product that needs to pass WHLK certification. Right now, there are three failed items in the test, and we want to consult you on how to resolve them:
- The test device selected is a HID-compliant device
- Test Item Interface
- Test Failures
- Currently, three tests have failed, and we can't fix them. Hope you can help analyze them.
4.1 Required Driver Attributes Test
The error message says: DriverFilePath = " " Runtime parameter QueryDriverFilePath is a zero-length string. Setup fixture 'RequiredDriverAttributesTests::Setup' for the scope 'RequiredDriverAttributesTests' failed. RequiredDriverAttributesTests::ValidateRequiredDriverAttributes
- DF - Concurrent Hardware And Operating System (CHAOS) Test (Reliability) and DF - Concurrent Hardware And Operating System (CHAOS) Test (Development and Integration)
The cause of these two errors is the same: WDTF_TEST: No devices were found for testing using the DQ.
- I checked the official website but couldn't find a solution. I hope a Microsoft staff member can help me analyze it and provide a solution. Thanks.
THANKS best regards

2026-09-03T02:56:58.81+00:00 After importing the playlist from the official website, the test items reduced from 66 to 26. Does this mean only these 26 items need to pass for WHLK certification?
