Java-based Combinatorial Test Modeling

Combinatorial testing is a black-box testing technique, which detects failures in the system under test. It reduces the number of test cases compared to exhaustive testing by applying combination strategies. Many generation algorithms and combinatorial testing tools have already been developed. Recent studies have focused on the integration of combinatorial… Read more
