Abstract
A computer implemented process for detecting errors in computer systems including the steps of executing sequences of instructions of a software program on each of a reference system and a test system, detecting and recording state of the reference system and the test system at comparable points in the execution of the program, and comparing the detected state of the reference system and the test system at selectable comparable points in the sequence of instructions including the end of the sequence of instructions. In a particular embodiment, the execution of portions of the sequence of instructions between selectable comparable points on each of the reference system and the test system is automatically replayed if a difference in compared state of the systems is detected.
