Validation of object oriented metrics using open source software system

Abstract

In today's environment the relevance of Free Open Source Software Systems is understood and appreciated both in academia and research. The debate about the pros and cons of the open source vis-à-vis proprietary software has been raging from ages ever since Richard Stallman founded the Free Software Foundation in 1985. With the changing trends in the domain of Object Oriented Systems there is a need to measure the fault predictability of software metrics on open source software systems. In this paper we present the results of empirical study which was conducted using open source software, JHotDraw 7.5.1. We computed the object oriented metrics, proposed by Chidamber and Kemmerer, and performed bug- class mapping for the software under study. We also studied the relationship between the revisions made to open source software and its software metrics measure.
