This paper describes a methodology for embedding dynamic behaviour into software components. The implications and system architecture requirements to support this adaptivity are discussed. This work is part of a European Commission funded and industry supported project to produce a...

Software products are often built from commercial-off-the-shelf (COTS) components. When new releases of these components are made available for integration and testing, source code is usually not provided by the COTS vendors. Various regression test selection (RTS) techniques have been developed...

The overall goal of software testing is to disclose defects efficiently (i.e. minimal time and cost) and effectively (i.e. maximum faults detected). It takes time to understand what to test, to generate test cases, to execute the test suite and to analyze the results. In a situation where one...

Access control is a mechanism for achieving confidentiality and integrity in software systems. Access control policies (ACPs) define how access is managed and the high-level rules of who can access what information under certain conditions. Traditionally, access control policies have been...
