Testability Measurement Framework Design Phase Perspective

Abstract: Measuring testability early in the development life cycle considerably reduces the overall development cost, effort and rework. It is very expensive and error prone decision to correct the design to get better testability after the coding has started.
This paper proposes a testability measurement framework for object oriented software concerning at design phase. This framework correlates the testability factor with object oriented design properties and also correlates design properties with object oriented design metrics. No such framework has been presented in the literature that accurately measure testability of object oriented software taking design phase into consideration. The proposed framework reduces the gap between object oriented design properties, metrics and testability. This framework measures effort in measuring testability of object oriented software early at design phase and makes it possible to produce reliable end product within time and budget.
