WPD Compliance Stress Tests
This test exercises the driver by using the Windows Portable Device (WPD) API and validates that the device or driver complies with the Windows Hardware Certification requirements. This test is required to run for at least 24 hours as a prolonged stress test.
Note
This test does not cover the following items:
Legacy driver testing (only WPD class drivers are tested)
Device-protocol-specific requirements (this testing is covered in separate certification tests)
Digital Rights Management testing

Running the test
Before you run the test, complete the test setup as described in the test requirements: Device.Portable Testing Prerequisites.
Troubleshooting
For troubleshooting information, see Troubleshooting Device.Portable Testing.
When you are troubleshooting this test, note the following:
This test supports verbose logging when in manual test case selection mode. When the application is running, in Options > Logging Options, select Destination: Window, and then select Level: 10.
If no test cases are available from the test case selection tree, make sure that the device is plugged in.
For more information about requirements for portable device drivers, see Basic WPD Device Driver Requirements.
More Information
The WPD Compliance Stress Tests runs as a C++ application. When run outside HCK Studio, there is a test case selection user interface and test suites can be defined using test profiles. The test is fully automated and provides a Pass/Fail result for each requirement. The test validates the following for a WPD driver and the device connected to it.
Device/driver passes these common scenarios for content types and formats that it supports:
Object hierarchy enumeration
Object property retrieval
Object resource reads from device
Object resource writes to device
Object deletion
Power management
Device-generated or driver-generated events
Device/driver supports the following known function categories:
Required object properties and attributes
Resources and attributes
Function category requirements
Recommended:
WPD_FUNCTIONAL_CATEGORY_STORAGE
WPD_FUNCTIONAL_CATEGORY_DEVICE
WPD_FUNCTIONAL_CATEGORY_SMS
Optional:
WPD_FUNCTIONAL_CATEGORY_STILL_IMAGE_CAPTURE
WPD_FUNCTIONAL_CATEGORY_AUDIO_CAPTURE
Content type and format requirements
If a content type is not supported, the format support will not be verified. There are no strict requirements on the format or content type, because this is typically an implementation detail for device firmware. The driver can report support for any format or content type, as long as it passes the functional scenario tests that use objects of formats that it supports, like transfer, deletion, and enumeration. These formats and content types can serve as a guideline:
Recommended content type: WPD_CONTENT_TYPE_AUDIO
Recommended formats:
WPD_OBJECT_FORMAT_WMA
WPD_OBJECT_FORMAT_MP3
Optional content type: WPD_CONTENT_TYPE_VIDEO
Recommended format: WPD_OBJECT_FORMAT_WMV
Optional content type: WPD_CONTENT_TYPE_IMAGE
Recommended formats:
WPD_OBJECT_FORMAT_BMP
WPD_OBJECT_FORMAT_EXIF
WPD_OBJECT_FORMAT_GIF
WPD_OBJECT_FORMAT_ICON
WPD_OBJECT_FORMAT_JFIF
WPD_OBJECT_FORMAT_JP2
WPD_OBJECT_FORMAT_JPX
WPD_OBJECT_FORMAT_PNG
WPD_OBJECT_FORMAT_TIFF
Optional content type: WPD_CONTENT_TYPE_DOCUMENT
Optional formats:
WPD_OBJECT_FORMAT_HTML
WPD_OBJECT_FORMAT_TEXT
