Testability Assessment of Aspect Oriented Software Using Multicriteria Decision Making Approaches

Testability is an essential criterion for software quality and it is always difficult to measure. Multicriteria Decision Making (MCDM) approaches are very effectively and widely used in predicting the quality of the software. MCDM techniques are very helpful in ambiguous range of decisions. It has the ability to grip the uncertainty of pairwise comparisons. In this paper, multicriteria decision making approach has been used for qualitative assessment of aspect oriented software. MCDM approaches applied in this paper for testability predictions are Analytical Hierarchy Process (AHP), Fuzzy AHP (FAHP) and Preference Ranking Organization Method of Enrichment Evaluations (PROMETHEE-2). These approaches used for decision making through uncertainty of expert decisions. A pairwise comparison has been made based on expert judgements to a certain extent than exact numerical values. Four aspect oriented programs have been compared based on five quality attributes of software testability. Initially, the validations of software testability factors have been made through AHP. Ranking of programs are made through AHP, fuzzy AHP and PROMETHEE-2 approaches. Results show that the applied approaches are efficient and proved its suitability for the prediction of the testability of aspect oriented programs.
