The Testability of Distributed Real-Time Systems / Edition 1

by Werner Schütz

Overview

BY H. KOPETZ A real-time computer system must provide the intended service in two di­ mensions: the functional (value) dimension and the temporal dimension. The verification of a real-time system implementation is thus necessarily more com­ plex than the verification of a non-real-time system which has to be checked in the value dimension only. Since the formal verification techniques of temporal properties have not yet matured to the point where these techniques can be used in practical system development, systematic design and testing are the only alternatives for the development of dependable real-time systems. At present, up to and more than fifty percent of the development eff'ort of complex real-time computer systems is spent on testing. The test activities are thus a significant cost element in any real-time system project. The attack on this cost element has to proceed from two fronts: the design for testability and the development of a systematic test methodology supported by an appropriate tool set. This book covers both of these topics.

Editorial Reviews

For readers with some general knowledge of testing both distributed and real-time systems, focuses on the operational aspect of testing such systems. Identifies the principal problems that must be kept in mind, such as organization, observability, and environment simulation; argues that, even more than for ordinary software, the testing is highly influenced by the particular architecture; and derives a test methodology for the time-triggered system MARS, explaining how the method exploits the particular characteristics of the architecture.
