Analysis Model of Program Reading Process in Software Debugging

概要

This paper proposes a model for analyzing the reading process in software debugging. The model provides quantitative and objective visions to human's debugging activity, and provides framework for clarifying good- and/or bad-process for program reading. We have conducted experiments to observe debugging processes and collected process data based on the model. Some hypotheses such as "Expert subjects spend more time to read the faulty module than novice subjects do." were actually rejected; and, some other hypotheses such as "Reading the modules that have no dependence with faulty module degrade the debug efficiency." were accepted. The result of experiment suggested that explicit and quantitative evaluation of program reading process becomes possible by using the proposed model.
