Combinatorial Testing with Constraints for Negative Test Cases
Konrad Fögen, Horst Lichter · 2018
Constraint handling is an important extension of combinatorial testing to exclude irrelevant combinations which could otherwise lead to the input masking effect. A special handling of invalid values is also important because of potential input masking. Unfortunately, existing CT approaches only consider invalid values explicitly. Invalid value combinations are equally important but only indirectly supported . Therefore, we present a concept that allows to specify invalid value combinations as logical expressions to generate negative test cases.
