Transcript

  • 1. Software Testing: |Art - Practice|=? Aditya Mathur Purdue University Department of Computer Science SERC Showcase Ball State University Muncie, IN November 11-12, 2009
  • 2. Objective <ul><ul><li>Identify gaps, and their cause, in state-of-the-art and state-of-practice in the area of software testing and quality assurance. </li></ul></ul><ul><ul><li>Make recommendations on how to close the gaps identified. </li></ul></ul>
  • 3. Benefits <ul><li>Companies </li></ul><ul><ul><li>Aid to strategic planning </li></ul></ul><ul><ul><li>Improvement in product quality </li></ul></ul><ul><li>NSF </li></ul><ul><ul><li>Determination of funding priorities </li></ul></ul><ul><li>Researchers </li></ul><ul><ul><li>Choice of problems </li></ul></ul>
  • 4. Current Scenario Faculty NSF Proposals Accept Reject Companies Available (..but are these used?) Tools Techniques Are these useful? Are these scalable? Does novelty really matter? How does NSF assess the utility of an engineering tool/technique?
  • 5. Method: Subjects <ul><ul><li>12 companies who are willing to participate in the study </li></ul></ul><ul><ul><li>SERC and non-SERC companies to be considered </li></ul></ul>
  • 6. Method: State of the Art <ul><ul><li>Test generation </li></ul></ul><ul><ul><li>Test quality </li></ul></ul><ul><ul><li>Test process, metrics </li></ul></ul><ul><ul><li>Others? </li></ul></ul>
  • 7. Method: State of practice <ul><li>Specific techniques in </li></ul><ul><ul><li>Test generation </li></ul></ul><ul><ul><li>Test quality </li></ul></ul><ul><ul><li>Test process, metrics </li></ul></ul><ul><ul><li>Test phases: unit, integration, system, regression </li></ul></ul><ul><ul><li>Debugging </li></ul></ul><ul><ul><li>Others? </li></ul></ul>
  • 8. Method: Data collection <ul><li>Visit each company for 1-week </li></ul><ul><li>Interview testers and managers </li></ul><ul><li>Write summary report for each company </li></ul><ul><li>Write project report </li></ul><ul><ul><li>Companies anonymized </li></ul></ul><ul><ul><li>Gaps </li></ul></ul><ul><ul><li>Causes </li></ul></ul><ul><ul><li>Recommendations </li></ul></ul>
  • 9. Sample Questions <ul><li>What test generation techniques do you use in unit testing? System testing? </li></ul><ul><li>What metrics do you use to determine the adequacy of your tests in system testing? </li></ul><ul><li>Do you use finite state modeling and test generation using advanced methods such as the Wp method? </li></ul><ul><li>What commercial/open source tools, e.g., UPPAAL, do you use for testing real-time properties of your application? </li></ul><ul><li>Do you use timed I/O Transition Systems for modeling and test generation for real time systems? </li></ul><ul><li>Do you generate tests during the requirements phase of the life cycle? </li></ul>
  • 10. Past Work <ul><li>Grindal, Jeff Offutt, and Jonas Mellin, 2006 </li></ul><ul><ul><li>12 companies surveyed </li></ul></ul><ul><ul><li>Focus on process </li></ul></ul><ul><ul><li>Lacks specific techniques and tools </li></ul></ul><ul><li>Beer and Ramler 2008 </li></ul><ul><ul><ul><li>One company [Siemens] </li></ul></ul></ul><ul><ul><ul><li>Focus on “role of experience” in software testing </li></ul></ul></ul>
  • 11. Budget <ul><li>Duration: July 2010-June 2011 </li></ul><ul><li>Total: $100K (Salary, indirect costs, travel) </li></ul><ul><li>NSF: $50K </li></ul><ul><li>Companies: $50K. (approx) $5K/company </li></ul>
