1. A method comprising the steps of: storing a fault injection routine in at least one predefined memory location; modifying an original clock interrupt service routine of an operating system to create a modified clock interrupt service routine that comprises a pointer to the at least one predefined memory location; retrieving, from an interrupt vector table of the operating system, a clock vector pointer to the modified clock interrupt service routine; executing the modified clock interrupt service routine; transferring control to the fault injection routine through employment of the pointer to the at least one predefined memory location in the modified clock interrupt service routine; executing the fault injection routine.
