ANALYSIS OF TOOLS FOR OBTAINING CHIDAMBER AND KEMMERER METRICS FROM SOFTWARE PROJECTS DEVELOPED IN JAVA

Abstract

Chidamber and Kemerer Metrics (CK Metrics) is a widely used set of metrics designed to measure properties in object- oriented software. The CK Metrics set includes six indicators, each of which provides representation into different aspects of software development and implementation. The object-oriented Java programming language still remains one of the main ones for creating both server-side software and native mobile applications for Android OS and desktop applications for stationary PCs. This paper provides an analysis of tools that can be used to obtain numerical values of metrics from the CK Metrics set from software projects written using the Java programming language. A description and a brief assessment of the usability of the following tools are provided: ck, ckjm, ckjm-extended, CodeMR,, Metrics Reloaded, Metrics Tree.The tools are mainly presented, which are distributed open source, with the exception of CodeMR, which has a limited free and paid full-featured version. The tools presented in the analysis can be divided into two groups in terms of user interaction: via the command line interface and as plugins for the IntelliJ integrated development environment, which can be de facto called the standard for developing software implemented in Java. Tools for interaction via the graphical user interface are not presented in this analysis.The results of the analysis will help to make the right choice of a tool for obtaining numerical values of metrics from the CK Metrics set, based on the specific requirements of the developer or researcher and achieve the desired result with less time spent on independently studying the capabilities of the corresponding tool.
