DF - PNP Cancel Stop Device Test (Development and Integration)
As with the removal test, the test application attempts to add an upper filter to the target device stack and then restart the device stack by using SetupDiCallClassInstaller with DIF_PROPERTYCHANGE. If this attempt is not successful (that is, if someone on the target device stack failed the query-remove IRP), the test restarts the computer to test rebalance.
This test initiates a rebalance procedure, but the filter driver deliberately fails the query stop IRP. The order of IRPs looks like IRP_MN_QUERY_STOP_DEVICE (which is failed by the filter driver while coming up, causing a cancellation of rebalance) and IRP_MN_CANCEL_STOP_DEVICE. The resources of the device do not change.
- Test binary: Devfund_PnPDTest.dll
- Test method: PNPCancelStopDevice
The Disable Enhanced Device Testing (EDT) Support test uninstalls the test filter driver (msdmfilt.sys) as an upper filter on devices specified using the DQ parameter. This test filter gets installed as part of running tests in this test category
- Test binary: Devfund_PnPDTest.dll
- Test method: DisableEnhancedDeviceTestingSupport

Parameters
| Parameter name | Parameter description |
|---|---|
| DQ | A WDTF SDEL query that is used to identify the target device(s) - https://go.microsoft.com/fwlink/?LinkId=232678 |
| Wpa2PskAesSsid | Required ONLY if DUT or one of its child devices is a WiFi adapter. Please provide SSID of a WPA2 AES WiFi network that the test can use to test the WiFi adapter. The default is 'kitstestssid'. |
| Wpa2PskPassword | Required ONLY if DUT or one of its child devices is a WiFi adapter. Please provide password of the WPA2 AES WiFi network specified using the Wpa2PskAesSsid parameter. The default is 'password'. |
| WDTFREMOTESYSTEM | Required ONLY if DUT or one of its child devices is a wired NIC that doesn't have an IPv6 gateway address. If determined to be required, please provide an IPv6 address that the test NIC can ping to test network I/O. Eg: fe80::78b6:810:9c12:46cd |
| DriverVerifierAdditionalDrivers | Additional drivers that should have Driver Verifier enabled |
| DriverVerifierExcludedFlags | Placeholder for Driver Verifier flags that may be manually excluded for the test run |
| MultiDeviceHardwareIdSdelQueryHardwareID | Multi Device SDEL |
| MultiDeviceInstanceIdSdelWDKDeviceID | Device id of DUT |
| DriverVerifierCustomizeConfiguration | Specifies that this test may want to automatically update Driver Verifier settings |
| TestCycles | Number of cycles to run the test for. |
| DoSimpleIO | True or False. Runs SimpleIO (if found) on test devices before and after performing PNP operations. |
| IOPeriod | Time period in minutes to run SimpleIO (if found). |
| DoConcurrentIO | True or False. Uses WDTF concurrent IO interface to send I/O requests to target device stacks while performing PNP operations. |
