This talk will present change impact analysis, presenting the algorithms and empirical results obtained with Chianti, our CHange Impact Analysis Tool. Chianti is implemented as an Eclipse plug-in, and now is publicly available from the Prolangs website (http://prolangs.rutgers.edu/). We also will discuss experiences with our newer tool JUnit/CIA and the Crisp module in Chianti. JUnit/CIA links change impact analysis with unit testing (in the JUnit system) to identify those parts of an edit most likely to have contributed to a worsening test outcome, by classifying the changes according to the outcomes of the tests they affect. Crisp forms intermediate versions of a program by adding a partial edit to the original program version, allowing incremental exploration of the effects of an edit. We also will present a new heuristic for ranking the likelihood that a part of the edit might be failure-inducing, thus directing the exploration of intermediate program versions. Initial empirical results will be reported.
