SOFTWARE TESTING

STRUCTURE-BASED (WHITE-BOX) TECHNIQUES

Structure-based test techniques are used to explore system or component structures at several levels. At the component level, the structures of interest will be program structures such as decisions; at the integration level we may be interested in exploring the way components interact with other components (in what is usually termed a calling structure); at the system level we may be interested in how users will interact with a menu structure. All these are examples of structures and all may be tested using white-box test case design techniques. Instead of exercising a component or system to see if it functions correctly white-box tests focus on ensuring that particular elements of the structure itself ...
