Device Driver Testing Tutorial

What is Device Drivers??

Device drivers are software programs they are in between hardware and software layers.

The hardware abstraction layer of the operating system (OS) interacts directly with the device driver subsystem to send and receive commands between the application software layer and the actual device hardware.

In device driver development understanding of hardware timings and commands is very important.

Strategies for testing drivers:-

Its better to use Automation Testing to find out most of the bugs
Better to test early stage in development to catch bugs to avoid more risk
Use configuration and device testing
Use Equivalence partition testing
