A Development-Testing-Maintenance model for software evolution

1. A Development-Testing-Maintenance model for software evolution Masterant: Galit Friedman Superior advisor: DR. AmirTomer Secondary advisor: Prof. Dov Dori

2. Research Goals • Raising the significant of software testing process • Improving software testing methodology in the following aspects: • Quality • Efficiency • Costs • Aiming for a unified testing process

3. Software testing is mostly referred as a stage in software development process. The outcomes: Testing plans are done in late stages of development Planning against development artifacts instead of user requirements Software testing process parallel to development process in software construction model Related work- Rational UP Origin ProblemSolution for origin problem

4. New Problems • Changes in any stage of development can influence testing integrity • Testing artifacts to manage • Testing is more complicated and resources requirements as time, tools and testers qualification are intensified

5. Research Solution • A triple process model, reserving all connections between development-testing processes for evolution control • Attendant uses of model for testing process improvement • Automating traceability and uses of model for efficiency improvement

6. Solution Methods • Expanding an existing model for software maintenance - The Propagation Graph

7. Solution Methods- Con.. • Using OPCAT for automation and OPM for formalization

8. Research evaluation • Test Case- “ExamPal” • Measurements for Quality: • Measurements for Efficiency: • Costs Evaluation

9. Summary • It started from testing point of view and expanded to complete life cycle • Shared points with some of the new researches • Status- after proposal approval • Next step- Building the test case
