If this query-remove IRP fails, the test restarts the computer to get the filter driver onto the device stack. This attempt results in a query-remove IRP.

The test attempts to install its upper-filter driver on the target device stack. The Device Removal test encompasses IRP_MN_QUERY_REMOVE_DEVICE, IRP_MN_CANCEL_REMOVE_DEVICE, and IRP_MN_REMOVE_DEVICE. Test method: PNPSurpriseRemoveAndRestartDevice This test uses the EDT filter driver to send IRP_MN_SURPRISE_REMOVAL to target device stacks.įor more information, see About the Surprise Removal test. This test uses the EDT filter driver to try to send IRP_MN_STOP_DEVICE to target device stacks. This test causes IRP_MN_QUERY_REMOVE_DEVICE and IRP_MN_REMOVE_DEVICE to be sent to target device stacks. Test method: PNPTryStopDeviceRequestNewResourcesAndRestartDevice It also manipulates the resource requirements of the devices to maximize the chances that new resources are allocated to devices. PNP Rebalance Request New Resources Device test Test method: PNPTryStopDeviceAndFailRestart The EDT filter driver then fails IRP_MN_START_DEVICE requests (that follow IRP_MN_STOP_DEVICE requests) to trigger the surprise removal of target devices. This test disables and enables the target devices. Test method: PNPDIFRemoveAndRescanParentDevice This test uses the SetupDi API to send a DIF_REMOVE request for the installers to remove the device. This test uses the EDT filter driver to send IRP_MN_CANCEL_STOP_DEVICE to target device stacks.įor more information, see About the Rebalance tests. This test uses the EDT filter driver to send IRP_MN_CANCEL_REMOVE_DEVICE to target device stacks.įor more information, see About the Device Removal tests. Test method: PNP_DisableEnable_With_IO_Before_And_After Test binary: Devfund_PNP_DisableEnable_With_IO_c

Disables and enables every device on the system using WDTF PnP action interfaces, see IWDTFPNPAction2::DisableDevice and IWDTFPNPAction2::EnableDevice methods for more information.

See Provided WDTF Simple I/O plug-ins for more information.

Tests I/O on every device on the system using WDTF Simple I/O plugins.

Verifies that there are no devices on the system reporting device problem codes.

This test performs I/O and basic PnP disable/enable on devices.

PNP (disable and enable) with I/O before and after Test method: PNP_DisableEnable_Reboot_With_IO_Before_And_After Test binary: Devfund_PNP_DisableEnable_Reboot_With_IO_c This test performs basic PnP disable/enable and I/O on devices with a system reboot. PNP (disable and enable) reboot with IO before and after Parameters: - see Device Fundamentals Test Parameters This test filter gets installed as part of running tests in this test category

This test uninstalls the test filter driver (msdmfilt.sys) as an upper filter on devices specified using the DQ parameter. Testĭisable Enhanced Device Testing (EDT) Support For information about enabling Driver Verifier, see Driver Verifier properties for driver projects. The PnP tests should be run with Driver Verifier enabled on the test computer.

The Plug and Play (PnP) tests execute various PnP-related code paths in the driver and user-mode components. This PnP testing is accomplished by using a combination of user-mode API calls (through the test application) and kernel-mode API calls (through an upper-filter driver). The PnP test provides a mechanism to test each of these separately, or to test them all together (that is, as a stress test). The Device Fundamentals PnP tests force a driver to handle almost all of the PnP IRPs however, there are three areas that are stressed specifically: removal, rebalance, and surprise removal.
