To get the most benefit from the Device Fundamental tests, your device should have a Simple I/O plug-in that can perform simple I/O to your device. This can be one of the default Simple I/O plugs that come with WDTF or one that you wrote. To see if your device type is supported and to determine if there are specific requirements for testing, refer to Provided WDTF Simple I/O plug-ins.
Whether you start writing driver tests with the templates provided in the Windows Driver Kit (WDK), or whether you create the tests on your own, the Microsoft Windows Device Testing Framework (WDTF) enables you to create and extend device-centric, scenario-based automated tests.
Start testing your C# apps by using the testing tools in Visual Studio. Learn to write tests, use Test Explorer, create test suites, and apply the red, green, refactor pattern to write code.
