Testability estimation model (TEM OOD)

Abstract

Testability analysis early in the development process is a criterion of crucial importance to software developers, designers and the managers. Early estimation of testability, exclusively at design phase assists designers to improve their designs before the coding starts. Consequently, it significantly reduces rework during and after implementation, as well as designing effective test plans, better project and resource planning. An effort has been put forth in this paper to identify the major factors contributing in testability estimation at design phase. Further, a model is developed to quantify software testability in design phase. Furthermore, the correlation of Testability with these factors has been tested and justified with the help of statistical measures. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
