Multi-objective Genetic Optimization for Noise-Based Testing of Concurrent Software

conference paper

English

Testing of multi-threaded programs is a~demanding work due to the many possible thread interleavings one should examine. The noise injection technique helps to increase the number of thread interleavings examined during repeated test executions provided that a~suitable setting of noise injection heuristics is used. The problem of finding such a~setting, i.e., the so called test and noise configuration search problem (TNCS problem), is not easy to solve. In this paper, we show how to apply a~multi-objective genetic algorithm (MOGA) to the TNCS problem. In particular, we focus on generation of TNCS solutions that cover a~high number of distinct interleavings (especially those which are rare) and provide stable results at the same time. To achieve this goal, we study suitable metrics and ways how to suppress effects of non-deterministic thread scheduling on the proposed MOGA-based approach. We also discuss a~choice of a~concrete MOGA and its parameters suitable for our setting.  Finally, we show on a~set of benchmark programs that our approach provides better results when compared to the commonly used random approach as well as to the sooner proposed use of a~single-objective genetic approach.
