  1. An Approach to Measure Java Code Quality in Reuse Environment Master: Aline Timóteo Professor: Silvio Meira UFPE – Federal University of Pernambuco alt@cin.ufpe.br http://www.rise.com.br

  2. Summary • Motivation • An Approach to Measure Java Code Quality • Metrics Background • Quality Attributes x Metrics • Current Stage • Conclusion http://www.rise.com.br

  3. Motivation http://www.rise.com.br

  4. Reuse • What is reuse? • [Basili, 1991; Frakes, 1994] [Kruger, 1992] Reuse is a process of creating software systems from existing software rather than building software system from scratch. http://www.rise.com.br

  5. Reuse Program • Griss Model [Griss, 1994] • Reuse leveis • Sametinger Model [Sametinger, 1997] • Domain Abalysis, pilot project, Institutionalization • Commons Points: • Reuse Evironment needs: • Assets Repository • Search and recovery tools • ... http://www.rise.com.br

  6. Search and Recovery Tools [Garcia, 2006] • CodeFinder, Agora, CLARiFi, InteliZap, Strathcona, Bart ... • Efficiency in search time • Communication with different kinds of repository • Support to all development cicle http://www.rise.com.br

  7. The Problem • How to analyze the quality of the assets stored in the repository? http://www.rise.com.br

  8. Work Proposal http://www.rise.com.br

  9. Work Proposal • Basic Asset Retrieval Tool (B.A.R.T.) [Santos, 2006] • Tool for search and recovery assets in version control systems • The mais objective of B.A.R.T. System is: • To minimize the time of analysis and implementation • Increased the quality of software products through the facilitated access to reusable devices http://www.rise.com.br

  10. Work Proposal bartFilter Code Quality Metrics + Quality Attributes http://www.rise.com.br

  11. bartFilter analysis assets according with metrics and quality attributes Work Proposal Customer request bartFilter The server return assets according with the customer request http://www.rise.com.br

  12. Tools Analysis http://www.rise.com.br

  13. Tools Analysis • Metodology • Step 1: Selecting software metrics and quality attributes • Step 2: Apply GQM [GQM, 1994] (Goal, Question, Metrics) in selected metrics and quality attributes • Step 3: Select metrics tools and a project • Step 4: Collects project metrics • Step 5: Results Analysis http://www.rise.com.br

  14. Step 1: Selecting Software Metrics and Quality Attributes http://www.rise.com.br

  15. Step 2: Apply GQM in Selected Metrics and Quality Attributes http://www.rise.com.br

  16. Step 3: Select Metrics Tools and a Project • Metrics • Jdepend • Javancss • Refactorit • JHawk Metrics • Coverlipse • Burn http://www.rise.com.br

  17. Step 4: Collect Project Metrics http://www.rise.com.br

  18. Step 5: Results Analysis • We identified some improvement poits: • The metrics relation can’t be 1 to n, the best way is this relation to be n to m. • Improve the results representation, study statistical forms for it. • Define clear selection criterions for metrics and quality attributes. http://www.rise.com.br
