Test suite reduction can greatly save the test effort during regression testing. For software development with frequent minor updates, a good policy is to managing selective form regression testing, where the total set of test requirements is divided into two subsets: one is the set of concerned test requirements which ought to be covered by selected regression test cases; the other is the set of...
Combinatorial testing (also called interaction testing) is an effective specification-based test input generation technique. By now most of research work in combinatorial testing aims to propose novel approaches trying to generate test suites with minimum size that still cover all the pairwise, triple, or n-way combinations of factors. Since the difficulty of solving this problem is demonstrated to...
Interaction testing (also called combinatorial testing) is an cost-effective test generation technique in software testing. Most research work focuses on finding effective approaches to build optimal t-way interaction test suites. However, the strength of different factor sets may not be consistent due to the practical test requirements. To solve this problem, a variable strength combinatorial object...
Since automated fault localization can improve the efficiency of both the testing and debugging process, it is an important technique for the development of reliable software. This paper proposes a novel fault localization approach based on multi-level similarity of execution traces, which is suitable for object-oriented software. It selects useful test cases at class level and computes code suspiciousness...
Traditional interaction testing aims to build test suites that cover all t-way interactions of inputs. But in many test scenarios, the entire test suites cannot be fully run due to the limited budget. Therefore it is necessary to take the importance of interactions into account and prioritize these tests of the test suite. In the paper, we use the hybrid approach to build prioritized pairwise interaction...
Interaction testing offers a stable cost-benefit ratio in identifying faults. But in many testing scenarios, the entire test suite cannot be fully executed due to limited time or cost. In these situations, it is essential to take the importance of interactions into account and prioritize these tests. To tackle this issue, the biased covering array is proposed and the Weighted Density Algorithm (WDA)...
