3 Performance Test Necessities 3 > Have a test setup that resembles production in Hard- and Software setup Client load (LoadRunner, JMeter) Data(base) content (production data, benerator) > Neglecting any of these makes performance test results useless for production performance prediction! Load Generator 800 concurrent users Application Under Test Production Application Database Production Under Test Database 10M customers

4 4 benerator is the leading open source tool to address an essential necessity of performance testing: creating production-like data!

5 Production data 5 > performance testers like testing with production data, >...but face problems (e.g. for new software, outsourcing, privacy protection): availability and applicability of production data > Production data always reflects the past: No scenario testing No worst-case checks No fuzz tests > but performance testing always target at predicting future performance!

6 Data generator requirements 6 > Must-haves passing complex validation customizability / extendability performance > Desirable production data export + anonymization early applicability in projects (little initial effort) little maintenance effort with ongoing implementation > Nice to have platform independence reusability among companies and technologies

7 Databene Benerator 7 > Is the leading open source test data generator > Fulfills all the requirements above > available at > Reduces data definition effort from weeks to days! > Is easily extended for new system types and file formats > Has an Eclipse Plugin: Benclipse (
