Method on Change Impact Analysis for Object-Oriented Program

Software changes are inevitable during the process of software evolution. To accommodate the changes in the software process, it is necessary to analyze the impacts of the changes. Software change impact analysis (CIA) is a key technique for identifying unpredicted and potential effects caused by changes made to software. CIA allows developers assessing the possible effects of a change, which plays an important role in software maintenance. In this paper, we present the static CIA technology based on program dependence graph (PDG) through analyzing possible change impacts for Object-Oriented source code. An analysis prototype tool for C++ program is implemented. The experimental results show that the method is effective.
