Abstract

Testability is an important quality factor of object oriented software. Its correct measurement or evaluation always facilitates and improves the test process. A lack of testability contributes to a higher level test cost and changeable effort. However testability has always been an indefinable concept and its absolute estimation (measurement) or evaluation is a tough job. Researchers and practioners have always claimed that testability should be considered as key factors which have positive impact on software development in order to ensure the software quality customer satisfaction especially at design face. [29].

The purpose of this review report is to proposing a conceptual comparative evaluation considering the testability issues, limitation and to investigate the general testability factors and commonly accepted minimal set of testability factors with the help of the systematic literature review. In this paper initially we conduct a literature review to have broad knowledge of testability and its quality factors and associated measurements that are found exhibiting the number of different testability factors that are presented by different researchers in different perspective. Next we do a comparative analysis on software testability proposed by various experts/researchers including their contribution and limitation.
