Reuse

open access: yesACM SIGSOFT Software Engineering Notes, 2013
Testing effort consumes more than half of all development effort and is one of the important factors, which obstruct quality assurance. Software reuse enhances quality and productivity and at the same time reduces the time-to-market of the software products. As reuse applies to the development process, so too, it applies to the testing process. In this
