Test-suite augmentation for evolving software -- the process of augmenting a test suite to adequately test software changes -- is necessary for any program that undergoes modifications as part of its development and maintenance cycles. Recently, we presented a new technique for test-suite augmentation based on leveraging the propagation conditions for the effects of changes. Although empirical studies...
Automatic structural testing of programs becomes more and more popularin software engineering. Among the most rigorous structural coverage criteria, all-paths coverage requires to generate a set of test cases such that every feasible execution path of the program under test is executed by one test case. This article addresses different aspects of computability and complexity of constraint-based all-paths...
A major issue in software testing is the automatic generation of the inputs to be applied to the programme under test. To solve this problem, a number of approaches based on search methods have been developed in the last few years, offering promising results for adequacy criteria like, for instance, branch coverage. We devise branch coverage as the satisfaction of a number of constraints. This allows...
