Resumo
Traditionally, mutation testing is used for test set and/or test criteria evaluation
once it is considered a good fault model. Since static analyzers, in general, report a
substantial number of false positive warnings,
Objective: This paper uses mutation testing for evaluating an automated static analyzer.
The intention of this study is to define a prioritization approach of static warnings based
on their correspondence with mutations.
Method: We used mutation operators as a fault model to evaluate the direct correspondence
between mutations and static warnings. The main advantage of using mutation operators
is that they generate a large number of programs containing faults of different types,
which can be used to decide the ones most probable to be detected by static analyzers.
Results: The results obtained for a set of open-source programs indicate that: 1) correspondence
exists when considering specific mutation operators such that static warnings
may be prioritized based on their correspondence level with mutations; 2) correspondence
exists when considering specific warning categories such that, assuming we perform static
analysis considering these warning categories, mutation operators may be prioritized
based on their correspondence level with warnings.
Conclusion: It is possible to provide an incremental testing strategy aiming at reducing
the cost of both static analysis and mutation testing using the correspondence information.
On the other hand, knowing that Mutation Test has a high application cost, we identified
mutations of some specific mutation operators, which an automatic static analyzer is not
able to detect. Therefore, this information can used to prioritize the order of applying
mutation operators incrementally considering, firstly, those with no correspondence with
static warnings.
