| Popis: | Companies strive to implement continuous integration into their development process to ensure the quality of their systems. Regression testing within the CI process considers the efficient re-test of systems after changes. However, even with regression testing, it is not feasible to test all configurations from a highly-configurable software system due to the combinatorial-explosion problem. Numerous sampling algorithms have been proposed that aim at computing a considerably smaller yet sufficiently representative set of configurations to be tested. Those algorithms are typically evaluated with regard to efficiency (i.e., number of configurations in a sample and computational effort for generating a sample) and effectiveness (i.e., feature-interaction coverage or number of faults detected). In this paper, we argue that a further crucial characteristic of sampling algorithms is their tendency to produce similar configurations when applied consecutively to an evolving configurable system. We propose sampling stability as a new evaluation criterion for sampling algorithms. We present a procedure to compute the sampling stability of sampling algorithms based on the similarity between consecutive samples. In our evaluation, we compare the sampling stability of multiple established t-wise sampling algorithms on large real-world systems. |
