Abstract
A method, apparatus, software and data structure are disclosed for more efficient fault testing of system software. A table is used to track routines that have been subjected to induced faults. As call paths are encountered in operating the system software, the table is consulted to determine which call paths have not yet been subjected to induced exceptions. These call paths are then subjected to the exceptions, thereby improving uniformity of distribution of induced exceptions.
