Purpose – The primary purpose of this paper is to present a comprehensive strategy for performance, reliability and scalability (PSR) testing of multi-tier web applications. Design/methodology/approach – The strategy for PSR testing is presented primarily through examination of the intangible knowledge base in the PSR testing field. The paper also draws on relevant recent work conducted in the ...

As more third-party software components are available in the commercial market, more people begin to use the component-based software engineering approach to developing component-based programs. Since most ebusiness and e-commerce application systems are net-centered distributed systems, customers usually have very restricted system performance requirements. Hence, performance testing and evalu...

Performance prediction and measurement approaches for component-based software systems help software architects to evaluate their systems based on component performance specifications created by component developers. Integrating classical performance models such as queueing networks, stochastic Petri nets, or stochastic process algebras, these approaches additionally exploit benefits of compone...

Distributed Software Systems (DSS) are used these days by many people in the real time operations and modern enterprise applications. One of the most important and essential attributes of measurements for the quality of service of distributed software is performance. Performance models can be employed at early stages of the software development cycle to characterize the quantitative behavior of...

Software testing is indispensable for all software development. In software development practice, testing accounts for as much has 50% of total development efforts. Regression testing has been used to support software testing activities and assure the acquirement of appropriate quality through several versions of a software program. Regression testing, however, is too expensive because it requi...

Recent advances in mobile equipments and wireless communications are making the Internet increasingly heterogeneous in terms of network, hardware and software capacities. Moreover, resources availability on the Internet varies unexpectedly. Thus, providing an efficient access to multimedia services requires that multimedia streams be adapted according to the environment constraints. One approac...
