Prioritization techniques in combinatorial testing: A survey

Prioritization techniques have become an indispensable part of the software testing process. They are highly beneficial either due to resource or time constraints or when tester cannot execute the complete test set. Combinatorial test sets are generated with the aim to cover all the possible t-way interactions. In this paper, techniques to prioritize t-way test sets are studied. A comparative study is done of prioritization criteria used by researchers to prioritize t-way test sets. Different evaluation methods used by them are also discussed.
