Verification support apparatus, verification support method, and computer product

摘要

A verification support apparatus includes an identifying unit that, by using a pre-change specification and a post-change specification given before and after a specification change in a subject to be verified, identifies an area that has changed from among a plurality of specification items included in the post-change specification and a selecting unit that selects a specification item from among the areas identified by the identifying unit. The verification support apparatus further includes a searching unit that, by referring a transition graph concerning the specification items included in the post-change specification and by tracing specification items as origins of transitions from a starting point that is the specification item selected by the selecting unit, searches for a route made up of specification items affected by the specification change; and an output unit that outputs a search result of the searching unit.
