Slator Date Department Chair ABSTRACT A software metric is the measurement of a particular characteristic of a software program. These metrics are very useful for optimizing the performance of the software, managing resources, debugging, schedule planning, quality assurance and periodic calculation of software metrics increases the success rate of any software project. Therefore, a software metrics tool is developed in this research which provides an extensible way to calculate software metrics. The tool developed is a web-based application which has the ability to calculate some of the important software metrics and statistics as well. It also provides a functionality to the user to add additional metrics and statistics to the application. This software metrics tool is a language- dependent tool which calculates metrics and statistics for only C# source files. iii ACKNOWLEDGEMENTS Though only my name appears on the cover of this disquisition, a great many people have contributed to its production.

  • The Use of Summation to Aggregate Software Metrics Hinders the Performance of Defect Prediction Models
    IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, VOL. XX, NO. XX, XXX 2016 1 The Use of Summation to Aggregate Software Metrics Hinders the Performance of Defect Prediction Models Feng Zhang, Ahmed E. Hassan, Member, IEEE, Shane McIntosh, Member, IEEE, and Ying Zou, Member, IEEE Abstract—Defect prediction models help software organizations to anticipate where defects will appear in the future. When training a defect prediction model, historical defect data is often mined from a Version Control System (VCS, e.g., Subversion), which records software changes at the file-level. Software metrics, on the other hand, are often calculated at the class- or method-level (e.g., McCabe’s Cyclomatic Complexity). To address the disagreement in granularity, the class- and method-level software metrics are aggregated to file-level, often using summation (i.e., McCabe of a file is the sum of the McCabe of all methods within the file). A recent study shows that summation significantly inflates the correlation between lines of code (Sloc) and cyclomatic complexity (Cc) in Java projects. While there are many other aggregation schemes (e.g., central tendency, dispersion), they have remained unexplored in the scope of defect prediction. In this study, we set out to investigate how different aggregation schemes impact defect prediction models. Through an analysis of 11 aggregation schemes using data collected from 255 open source projects, we find that: (1) aggregation schemes can significantly alter correlations among metrics, as well as the correlations between metrics and

  • Understanding the Syntactic Rule Usage in Java
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by UCL Discovery Understanding the Syntactic Rule Usage in Java Dong Qiua, Bixin Lia,∗, Earl T. Barrb, Zhendong Suc aSchool of Computer Science and Engineering, Southeast University, China bDepartment of Computer Science, University College London, UK cDepartment of Computer Science, University of California Davis, USA Abstract Context: Syntax is fundamental to any programming language: syntax defines valid programs. In the 1970s, computer scientists rigorously and empirically studied programming languages to guide and inform language design. Since then, language design has been artistic, driven by the aesthetic concerns and intuitions of language architects. Despite recent studies on small sets of selected language features, we lack a comprehensive, quantitative, empirical analysis of how modern, real-world source code exercises the syntax of its programming language. Objective: This study aims to understand how programming language syntax is employed in actual development and explore their potential applications based on the results of syntax usage analysis. Method: We present our results on the first such study on Java, a modern, mature, and widely-used programming language. Our corpus contains over 5,000 open-source Java projects, totalling 150 million source lines of code (SLoC). We study both independent (i.e. applications of a single syntax rule) and dependent (i.e. applications of multiple syntax rules) rule usage, and quantify their impact over time and project size. Results: Our study provides detailed quantitative information and yields insight, particularly (i) confirming the conventional wisdom that the usage of syntax rules is Zipfian; (ii) showing that the adoption of new rules and their impact on the usage of pre-existing rules vary significantly over time; and (iii) showing that rule usage is highly contextual.

  • Development of an Enhanced Automated Software Complexity Measurement System
    Journal of Advances in Computational Intelligence Theory Volume 1 Issue 3 Development of an Enhanced Automated Software Complexity Measurement System Sanusi B.A.1, Olabiyisi S.O.2, Afolabi A.O.3, Olowoye, A.O.4 1,2,4Department of Computer Science, 3Department of Cyber Security, Ladoke Akintola University of Technology, Ogbomoso, Nigeria. Corresponding Author E-mail Id:- [email protected] [email protected] [email protected] 4 [email protected] ABSTRACT Code Complexity measures can simply be used to predict critical information about reliability, testability, and maintainability of software systems from the automatic measurement of the source code. The existing automated code complexity measurement is performed using a commercially available code analysis tool called QA-C for the code complexity of C-programming language which runs on Solaris and does not measure the defect-rate of the source code. Therefore, this paper aimed at developing an enhanced automated system that evaluates the code complexity of C-family programming languages and computes the defect rate. The existing code-based complexity metrics: Source Lines of Code metric, McCabe Cyclomatic Complexity metrics and Halstead Complexity Metrics were studied and implemented so as to extend the existing schemes. The developed system was built following the procedure of waterfall model that involves: Gathering requirements, System design, Development coding, Testing, and Maintenance. The developed system was developed in the Visual Studio Integrated Development Environment (2019) using C-Sharp (C#) programming language, .NET framework and MYSQL Server for database design. The performance of the system was tested efficiently using a software testing technique known as Black-box testing to examine the functionality and quality of the system.

  • DRE) for Software
    Exceeding 99% in Defect Removal Efficiency (DRE) for Software Draft 11.0 September 6, 2016 Capers Jones, VP and CTO, Namcook Analytics LLC Abstract Software quality depends upon two important variables. The first variable is that of “defect potentials” or the sum total of bugs likely to occur in requirements, architecture, design, code, documents, and “bad fixes” or new bugs in bug repairs. Defect potentials are measured using function point metrics, since “lines of code” cannot deal with requirements and design defects. (This paper uses IFPUG function points version 4.3. The newer SNAP metrics are only shown experimentally due to insufficient empirical quality data with SNAP as of 2016. However an experimental tool is included for calculating SNAP defects.) The second important measure is “defect removal efficiency (DRE)” or the percentage of bugs found and eliminated before release of software to clients. The metrics of Defect Potentials and Defect Removal Efficiency (DRE) were developed by IBM circa 1973 and are widely used by technology companies and also by insurance companies, banks, and other companies with large software organizations. The author’s Software Risk Master (SRM) estimating tool predicts defect potentials and defect removal efficiency (DRE) as standard quality outputs for all software projects.

This combination of defect potentials using function points and defect removal efficiency (DRE) are the only accurate and effective measures for software quality.

  • Empirical Evaluation of the Effectiveness and Reliability of Software Testing Adequacy Criteria and Reference Test Systems
    Empirical Evaluation of the Effectiveness and Reliability of Software Testing Adequacy Criteria and Reference Test Systems Mark Jason Hadley PhD University of York Department of Computer Science September 2013 2 Abstract This PhD Thesis reports the results of experiments conducted to investigate the effectiveness and reliability of ‘adequacy criteria’ - criteria used by testers to determine when to stop testing. The research reported here is concerned with the empirical determination of the effectiveness and reliability of both tests sets that satisfy major general structural code coverage criteria and test sets crafted by experts for testing specific applications. We use automated test data generation and subset extraction techniques to generate multiple tests sets satisfying widely used coverage criteria (statement, branch and MC/DC coverage). The results show that confidence in the reliability of such criteria is misplaced. We also consider the fault-finding capabilities of three test suites created by the international community to serve to assure implementations of the Data Encryption Standard (a block cipher). We do this by means of mutation analysis. The results show that not all sets are mutation adequate but the test suites are generally highly effective. The block cipher implementations are also seen to be highly ‘testable’ (i.e. they do not mask faults). 3 Contents Abstract ............................................................................................................................ 3 Table of Tables ...............................................................................................................

  • Differences in the Definition and Calculation of the LOC Metric In
    Differences in the Definition and Calculation of the LOC Metric in Free Tools∗ István Siket Árpád Beszédes Department of Software Engineering Department of Software Engineering University of Szeged, Hungary University of Szeged, Hungary [email protected] [email protected] John Taylor FrontEndART Software Ltd. Szeged, Hungary [email protected] Abstract The software metric LOC (Lines of Code) is probably one of the most controversial metrics in software engineering practice. It is relatively easy to calculate, understand and use by the different stakeholders for a variety of purposes; LOC is the most frequently applied measure in software estimation, quality assurance and many other fields. Yet, there is a high level of variability in the definition and calculation methods of the metric which makes it difficult to use it as a base for important decisions. Furthermore, there are cases when its usage is highly questionable – such as programmer productivity assessment. In this paper, we investigate how LOC is usually defined and calculated by today’s free LOC calculator tools. We used a set of tools to compute LOC metrics on a variety of open source systems in order to measure the actual differences between results and investigate the possible causes of the deviation. 1 Introduction Lines of Code (LOC) is supposed to be the easiest software metric to understand, compute and in- terpret. The issue with counting code is determining which rules to use for the comparisons to be valid [5]. LOC is generally seen as a measure of system size expressed using the number of lines of its source code as it would appear in a text editor, but the situation is not that simple as we will see shortly.

  • Lightweight Requirements Engineering Metrics Designing And
    Universiteit Leiden ICT in Business and the Public Sector Lightweight Requirements Engineering Metrics Designing and evaluating requirements engineering metrics for software development in complex IT environments – Case study Name: Jenny Yung Student-no: s0952249 Date: 18/04/2019 1st supervisor: Werner Heijstek 2nd supervisor: Guus Ramackers Pagina 1 van 83 Abstract The software development industry is relatively young and has matured considerably in the past 15 years. With several major transformations, the industry continues to seek ways to improve their delivery. A while ago, the waterfall method was the standard option for software development projects. Today, agile methodology is used more frequently. New development engineering practices are developed like standardization, continuous integration or continuous delivery. However, the consensus of being predictable and repeatable is not yet there. Agile software development and delivery are still not sufficiently reliable, resulting in expensive and unpredictable projects. In this thesis, measurements in requirements engineering are introduced. This paper presents a maturity model to assess the requirements engineering in complex IT environments. Companies strive to improve their software production and delivery, and the study aims to find a lightweight requirements metric method. The method is compared with a library of abstract metric models. The case study is performed at three different companies, and experts evaluated the conceptual metric system. As a result, a Requirements Engineering Maturity scan (REMS) is created. The tool suggests appropriate generic requirements metrics to deal with the encountered project. The paper concludes a review with related work and a discussion of the prospects for REMS.
