Scenario based testing & test plan metrics based on a use case approach for real time UPS (uninterruptible power system)

Abstract

This paper describes a part of an extended use case approach for real time object-oriented software development. Its foundation is an object-oriented software design approach which partitions design schema into layered design component architecture of functional components called "design component unit". A use case action matrix contains a collection of related scenarios each describing a specific variant of an executable sequence of use case action units, which reflects the behavioral properties of the real time system design. Proposed scenario based testing and test plan metric measure and produce an ordering of this scenario set to enhance productivity, and promote and capitalize on test case reusability of existing scenarios. To illustrate the proposed approach uses an example of real time UPS (uninterruptible power system).
