Driver Install Tests (Device Fundamentals)
The Driver Install test category includes tests that uninstall and reinstall a driver several times to test install functionality. The tests initiate I/O testing against the driver and device after each reinstall. The tests are designed to improve the overall experience for end users who need to install and reinstall a device driver or a device.

This test uninstalls and reinstalls the drivers for selected devices, and runs I/O testing on devices. Test binary: Devfund_Reinstall_With_IO_BeforeAndAfter.wsc Test method: Reinstall_With_IO_Before_And_After Parameters: - see Device Fundamentals Test Parameters DQ IOPeriod |
About the ReInstall with I/O Before and After test
This test does the following:
- Verifies that the test device and its descendants are not reporting any device problem codes.
- Tests I/O on the test device and its descendants using WDTF Simple I/O plugins. See Provided WDTF Simple I/O plug-ins for more information.
- Reinstalls the original driver on the test device using IWDTFDriverSetupAction2::UpdateDriver method.
- Verifies that the test device and its descendants are not reporting any device problem codes.
- Tests I/O on the test device and its descendants using WDTF Simple I/O plugins. See Provided WDTF Simple I/O plug-ins for more information.
- Reboots the system if step #3 requires a reboot.
- Installs NULL driver on the test device using IWDTFDriverSetupAction2::UnInstallDriverPermanently method Reboots the system if a reboot is required.
- Reinstalls the original driver on device under test using IWDTFDriverSetupAction2::UpdateDriver method.
- Verifies that the test device and its descendants are not reporting any device problem codes.
- Tests I/O on the test device and its descendants using WDTF Simple I/O plugins. See Provided WDTF Simple I/O plug-ins for more information.
- Repeats step 1 - 10 several times.
Debug installation failures using the Setup API logs
The Setup API logs (setupapi.app.log and setupapi.dev.log) contain useful information to debug driver installation failures logged by this test. The Setup API logs can be found under %windir%\inf\ directory on the test system.
To increase the verbosity and potential usefulness of these logs, set the following registry key to 0x2000FFFF before running the Reinstall test:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\LogLevel
