Object Oriented Software Testability Survey at Designing and Implementation Phase

Software testability is coming out to be most frequent talked about subject then the underrated and unpopular quality factor it used to be in past few years. The correct and timely assessment of testability can lead to improvisation of software testing process. Though many researchers and quality controllers have proved its importance, but still the research has not gained much momentum in emphasizing the need of making testability analysis necessary during all software development phases. In this paper we investigate and review the factors, issues and methods of testability estimation of object oriented software systems during various phases of development life cycle. The paper hopes to change some common prejudices about testability. Improving software testability is key objective of our research by high lighting and relating the various factors individually affecting testability.
