Poster: CUTER: ClUstering-based TEst suite Reduction

Test Suite Reduction (TSR) approaches speed up regression testing by removing redundant test cases. TSR approaches can be classified as adequate or inadequate. Adequate approaches reduce test suites so that they completely preserve the test requirements (e.g., statement coverage) of the original test suites. Inadequate approaches produce reduced test suites that only partially preserve the test requirements. We propose a tool prototype for inadequate TSR and named it CUTER (ClUstering-based TEst suite Reduction). CUTER implements a clustering-based approach and a number of instances of its underlying process. We implemented CUTER as an Eclipse plug-in and applied it on 19 versions of four Java programs.
