ABSTRACT:
A test case generating apparatus for generating test cases used for verifying operations of an object, includes operation specification describing unit for describing operation specifications of the object using a plurality of parallel and/or hierarchical state transition diagrams, state transition diagram searching unit for searching the plurality of state transition diagrams described by the operation specification describing unit to select a transition from a predetermined state to a state on the state transition diagram, and outputting a selection result, and action/event relation managing unit for storing relations between actions and events, and controlling a transition selection operation of the state transition diagram searching unit by managing transitions which never occur in practice. The apparatus further includes parallel (hierarchy) relation managing unit for controlling the transition selection operation of the state transition diagram searching unit by managing the searching order of the plurality of parallel and/or hierarchical state transition diagrams described by the operation specification describing unit (and adequacy of transition coverage).
