摘要：Measuring testability early in the development life cycle especially at design phase is a criterion of crucialimportance to software designers, developers, quality controllers and practitioners. However, most of themechanism available for testability measurement may be used in the later phases of development life cycle.Early estimation of testability, absolutely at design phase helps designers to improve their designs beforethe coding starts. Practitioners regularly advocate that testability should be planned early in design phase.Testability measurement early in design phase is greatly emphasized in this study; hence, consideredsignificant for the delivery of quality software. As a result, it extensively reduces rework during and afterimplementation, as well as facilitate for design effective test plans, better project and resource planning ina practical manner, with a focus on the design phase. An effort has been put forth in this paper to recognizethe key factors contributing in testability measurement at design phase. Additionally, testabilitymeasurement model is developed to quantify software testability at design phase. Furthermore, therelationship of Testability with these factors has been tested and justified with the help of statisticalmeasures. The developed model has been validated using experimental tryout. Finally, it incorporates theempirical validation of the testability measurement model as the author’s most important contribution.
