Abstract: Testability can be used as a high impact quality indicator in the modern era of software development process. The complete process of testability always helps the developer by its correct measurement or evaluation. But its correct evaluation is not an easy task for the practitioners. Practitioners as well as researchers have always suggested that testability should be considered as a primary attribute towards achievement of quality software process. Software quality’s accurate measure depends on testability measurement, and as an outcome estimating efforts in measuring testability is a complex problem that requires considerable attention of researchers. Primary objective of this review report is to raise the testability issues with the limitation and to investigate the general testability factor and minimal set of commonly accepted testability factors, and proposing a conceptual comparative evolution. Here we review the literature to gain wide knowledge of testability and its quality factors and measurement presented by various researchers in different perspective.
