Maintaining traceability during object-oriented software evolution: a case study

This paper presents an approach to build and visualize traceability links and properties of a set of OO software releases. The process recovers an “as is” design from C++ software releases, compares recovered designs at the class interface level, and helps the user to deal with inconsistencies by pointing out regions of code where differences are concentrated. The comparison process exploits edit distance and a maximum match algorithm and has been experimented with 9 releases of a library of foundation classes. Results as well as consideration related to presentation issues are reported in the paper
