Device-driver development and testing is a complex and error-prone undertaking. For example, a single driver may support dozens of devices, and a developer may not have access to any of them. As a result, many Linux driver patches include the comment "compile tested only." Furthermore, testing error-handling code is difficult, as it requires faulty inputs from the device.
