Abstract

Prior software testing techniques called for rippling of a program, and every portion thereof, through a rigidly defined test sequence. This required an excessive number of people and a correspondingly large amount of time and, on the whole, was unnecessary. Generally, the updated program is made up of a number of portions that have a known or predictable defect percentage. Based on this knowledge, testing of altered or updated (combined, later version, etc.) programs can be efficiently managed and quality improved. The known or predictable defect percentage of each portion of the program can be readily converted into a factor which can serve as a pointer to a starting point in a testing sequence. In many instances, this starting point is substantially removed from the beginning of the testing sequence.
