A Tool for Regression Testing

Abstract

Regression Testing involves running previous test cases on new versions of software. The challenge is to reduce the number of test cases to be rerun by avoiding cases that are "guaranteed" not to reveal any defects in the new version. The problem is even more difficult when software involves Commercial-off-the-shelf (COTS) components since source code for such components are often not available to component users. In this paper we describe a tool for regression test selection called RegTest. RegTest uses a two stage black-box selection strategy based on information on version changes provided by component developers. RegTest is developed using Java and XML.
