METHOD FOR LOCATING DEFECT IN NEW VERSION OF SOFTWARE PROGRAM, METHOD FOR SUBSTITUTION ORDER OF PROCEDURES OF NEW VERSION OF PROGRAM PRODUCING DEFECT, AND COMPUTER SYSTEM (EFFICIENT DEFECT LOCATION IN NEW CODE VERSIONS)

摘要

To provide methods and a computer system that efficiently locate codes causing defects of upgraded programs.SOLUTION: A method comprises: receiving a source code of a golden version program and a source code of a next version program; generating a first entry point table (first EPT) of a new version program and a second entry point table (second EPT) of a golden version program; performing a series of substitutions of sets of procedures between the second EPT of the golden version program and the first EPT of the new version program; and identifying an individual procedure determined to produce a defect by performing substitution until change in the presence of the defect is detected, and proceeding to next substitution if the change is not detected.SELECTED DRAWING: Figure 3
