A Practical Extension of Pairwise Testing

For the interaction testing, there have been a variety of tools to efficiently generate test cases using Pair wise or In-Parameter-Order (or IPO) technique. Especially, PICT and AETG among these tools provide not only a combination technique of input parameters to generate test cases but also practical features to create feasible test cases in industry. Nonetheless, practicing these tools in industry has still some difficulties, designing test cases using these tools is applied into only very few areas of features of a system to be tested. Therefore, this paper proposes additional features which could overcome these limitations and extend features to be designed, it could reflect test engineers´ considerations or behaviors when designing feasible test cases related to generating sequential test scenario, considering exceptional test cases, writing readable test cases, and iteratively updating test cases. Consequently, the given system this paper suggests could give test engineers free time to focus on test design engineering to advance test design skills or techniques, because it makes it possible that a time consuming and labor-intensive work like not only repetitively executing test cases but also even iteratively re-designing test cases could be assigned to outsourcing resources or testers with low-cost or low-capability.
