2 2TSI-11/02 TSI Company background Enterprise NATURAL development today Categories of testing Testing tools Conclusion Agenda

3 3TSI-11/02 Company Background Established in Personnel Leading provider of systems software products and consulting services for Software AG customers Over 500 customers Worldwide presence

4 4TSI-11/02 Enterprise NATURAL Development Today Do more and do faster with less Wear many hats: analyst, designer, coder, tester, DBA, guru… Maintain unfamiliar, undocumented systems Adapt legacy systems to new technologies Work in teams of varying skill levels –People without ADABAS/NATURAL skills –Contractors

5 5TSI-11/02 Categories of Testing Unit Integration Performance/Load/Stress System Regression/Maintenance User Acceptance Documentation

6 6TSI-11/02 Unit Testing Module-oriented Parallelizable White box approach Stubs and drivers (Construct sites have advantage)

7 7TSI-11/02 Integration Testing Test units as a whole structure Discover interface errors Incremental build-up

8 8TSI-11/02 Performance/Load/Stress Testing Oriented to tested integrated system Test performance under various load conditions, including extreme Monitor resource usage

9 9TSI-11/02 System Testing Oriented to tested integrated system Exercise all required functions Verify completeness of functions and testing strategies

10 10TSI-11/02 Regression/Maintenance Testing Identify where changes have resulted in unintended behavior or new errors Comparative in nature Defined test cases
