Abstract

Lazy systematic unit testing with JWalk is compared against regression testing with JUnit, the leading agile testing tool. JWalk produced exhaustive test sets more quickly and recalculated full state and transition coverage, when testing modified or extended classes. For the same time and effort invested, JWalk tested up to two orders of magnitude more paths than manual tests created for JUnit by an expert tester.
