WDF gave an object oriented look to the traditional Windows Driver Model (WDM). One of the results was that driver developers could focus on the core functionalities of their device, and could leave the Windows OS specific stuff to the new frameworks.
While the development of device drivers has been simplified, testing them is still like a complex puzzle for many people. The traditional approach is based on ad-hoc means of generating test plans and test cases that treat device drivers as a black box. As a result, critical features are missed out or don’t get enough attention. In this blog post, I will try to structure device driver testing by listing the (more…)
