A system and method for validating whether communications between a device driver and a hardware device conform to a communication specification is presented. A validation module obtains a communication specification identifying rules for validating whether communications between a device driver and a hardware device conform to the specification. A redirection module redirects communications between the device driver and the hardware device to the validation module. Based on an individual communication, as well as the context in which an individual communication is made, the validation module validates whether the communication conforms to the communication specification.

System and method for validating communication specification conformance between a device driver and a hardware device

A system and method for providing an extensibility model to create device simulators. The system and method provide a generalized framework for the simulation of hardware devices controlled by software drivers with user and kernel mode programmability. The present invention also provides a framework that facilitates communication between applications operating user address space of an operating system and device drivers and device simulators operating in kernel mode address space of the operating system. In one embodiment, a framework provides a bi-directional communication channel that allows a test application in user address space of an operating system to communicate with a computer component operating in kernel address space of the operating system.
