Combinatorial Robustness Testing with Negative Test Cases

Error-handling is an important means to improve the robustness of a system and testing error-handling is crucial to ensure its correctness. In this paper, we argue that error-handling leads to input masking which requires special treatment in for combinatorial testing. Therefore, we propose an extension to combinatorial testing including a robustness fault model and robustness combination strategy. We also provide an evaluation which compares its efficiency to normal combinatorial testing.
