Presentation Transcript

  1. Testing research directions: an industrial perspective Ashok Sreenivas TRDDC, Pune

  2. Primary problems • Still very expensive • 40-50% of time/effort • Guarantees on quality very poor • What kind of defects cannot occur? • What have I tested?

  3. Test evolution • All software has very long lives • Maintenance / enhancement cycles • Developing regression test-suites • Test selection • Some work done on test prioritisation • How to evolve test-suites for such systems? • Testing often inadequate and ad-hoc • Completeness, coverage …

  4. Use of formal methods • Precise descriptions • Can verify correctness at each step • Possibly other aspects than correctness too … • Guarantees on quality of testing • Quality improvement • Tools are a possibility • Cost reduction • The test-oracle problem?

  5. Domain specific formalisms • Formal spec idea not new! • Unfortunately, has not worked • General purpose formalisms may be too general! • Domain specific formalisms may be useful • Telecommunications: SDL, MSCs • Help in productivity and quality improvements • Systems with a persistent component?
