    The quality of software reengineering tools depends on that of the generic environments used in their construction. Some existing quality reengineering environments, such as the Software Refinery, go a long way to satisfying their particular design criteria, but fail to meet general open systems criteria. One remedial approach is to recreate some of the functionality of these environments by modif... View full abstract»

    Although many CASE tools for object-oriented methods (OO-CASE tools) have been proposed, few, if any, can verify that the constructed analysis and design models actually match the requirements of the system being developed. In order to realize this kind of verification, we propose a software development method amalgamating OO-CASE tools and algebraic specification techniques. We are developing an ...

    Testing of programs is important to increase the reliability of programs. Coverage is a ratio of the number of worked test events to all test events, and it is used as a metric of testing sufficiency and reliability. The test events are defined by a testing criterion. Some testing criteria are proposed for evaluating testing sufficiency of sequential programs. However, the criteria are inadequate ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (704 KB)

    The modular refinement of object-oriented specifications requires a sound theory of behavioural compatibility of classes. Such a theory will depend on the way in which objects of a class interact with their environment. This paper defines two notions of behavioural compatibility. Observational compatibility is relevant when an active object is placed within a passive environment and operational co... View full abstract»

    In contrast to the explosion of activity in object-oriented design and programming, little attention has been given to object testing. In our approach, a driver class and an oracle class are developed for each class-under-test (CUT). The driver class is based on a test-graph which partially models the CUT as a state machine, but with vastly fewer states and transitions. The oracle class provides e... View full abstract»

    Most current software metrics tend to be descriptive with weak prescriptive power; they are not rigid enough to support a successful engineering task as hardware metrics do. We propose the concept of software prescriptive metrics, which set up specific goals to achieve, and thus facilitate, quality control tasks. A general derivation procedure has been developed and applied to derive prescriptive ... View full abstract»

    Concurrent programs are more difficult to test than sequential programs because of nondeterministic behavior. An execution of a concurrent program nondeterministically exercises a sequence of synchronization events, called a synchronization sequence (or SYN-sequence). Nondeterministic testing of a concurrent program P is to execute P with a given input many times in order to exercise distinct SYN-... View full abstract»
