A considerable percentage of maintenance costs are due to regression testing, which consists of retesting the software after it is modified and is a crucial part of maintenance. Previous research on regression testing has mostly focused on the efficiency of this activity, while little emphasis has been placed on assessing and improving regression-testing effectiveness. The goal ofthis project is to fill this gap through the definition of techniques for (1) determining the adequacy of a test suite with respect to a set of software changes, and (2) providing automated support for designing and developing test cases that target inadequately-exercised changes. To achieve this goal, the research will perform three main tasks: define techniques that combine dependence- and state-related information to generate regression-test requirements for changed software; define techniques based on static and dynamic analysis for developing test cases that satisfy the identified requirements; and evaluate the techniques defined in the project through rigorous experiments and industrial case studies. This research directly addresses the stated goals of this program by targeting the development of techniques that can improve the processes ofconstructing and modifying software-intensive systems.
