Presentation: Test design revisited I-II

The talk is about the modern art of test design. We discuss shortly how test design is encapsulated into the software testing process, why risk management is unavoidable. We show a better approach for EP and BVA with a reliable test selection criterion using ON/OFF/IN/OUT data points. We also show how to reduce the number of tests in combinatorial testing preserving reliability. Our new methods are demonstrated by several examples and case studies.
