Generating the test inputs, that have high code coverage while minimizing the number of test inputs, is a practical but difficult problem. The application of symbolic execution in combination with SMT solvers gives a promising way to solve it. Recently, there have been several tools that help generating the test inputs for C programs, but their abilities are still limited, depending on the particular...
We describe a benchmark of publicly-available multi-threaded programs with documented bugs in them. This project was initiated a few years ago with the goal of helping research groups in the fields of concurrent testing and debugging to develop tools and algorithms that improve the quality of concurrent programs. We present a survey of usage of the benchmark, concluding that the benchmark had an impact...
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...
Software specification is an important element of the software development process. However, in most cases the specifications are out-of-date or even missing. One solution for this kind of problem is to use some process that infers the specification automatically. Work by Ernst et al (2000 ; 2002) has shown how specifications can be generated using program execution traces. These approaches are dependent...
We propose an approach to generate and execute tests of the conformance of a system to a given security policy. The method is rule-based: it generates test cases directly from a security policy expressed as a set of security requirements, using two relations: one between predicates appearing in the rules and elementary test cases, called tiles, used to test predicates in the system, and another one...
