Testability Analysis of Framework Based Software at Requirement Analysis Phase

Dependency on automated systems in every sphere of our life has raised a demand for enhanced quality and productivity along with the improved business performance of the software system. Researchers and practitioners in the field of software engineering are striving to achieve the same by applying many techniques. Reuse-oriented software development technique is one of the prevalent techniques, which promises to enhance the quality of the software. Testability is one of the external quality factors of the software, which affects quality of the software. This calls for the need of high testability of the system. Effectiveness of quality of software is increased if the testability analysis of a software system, developed by reuse-oriented approach, is performed in the very early stagerequirement analysis of the reuseoriented development life-cycle. The effort used to develop software systems using the reuse-oriented approach must be less than the effort used to develop them from scratch. The present paper identifies the factors, which affect the testability of the reuse-based software and presents few testability metrics and a model, which quantifies testability of the application in the requirement analysis phase of the application engineering.
