Case Study: Object-oriented Refactoring of Java Programs using Graph Transformation

In this case study for the transformation tool contest (TTC), we propose to implement object-oriented program refactorings using transformation techniques. The case study proposes two major challenges to be solved by solution candidates: (1) bi-directional synchronization between source/target program source code and abstract program representations, and (2) program transformation rules for program refactorings. We require solutions to implement at least two prominent refactorings, namely Pull Up Method and Create Superclass. Our evaluation framework consists of collections of sample programs comprising both positive and negative cases, as well as an automated before-after,testing procedure.
