Designing test cases for one single input parameter is quite simple - but how do you design test cases for many different input parameters? This is really challenging and results in a combinatorial explosion of test cases. The classic question for effective testing is always, "Given limited time and resources, which of the combinations should be tested?"

This tutorial describes the underlying problems and challenges in test case design for combinatorial testing and discusses many different application scenarios. After explaining possible solutions using different testing techniques, an overview about supporting tools is given. Furthermore, successful experiences gained from real-world projects are presented which clearly show the necessity and benefits of this approach.

After this tutorial participants will not only understand that combinatorial testing occurs everywhere in a tester's (and developer's!) life, but they will especially have the necessary understanding to do effective and efficient test case design for combinatorial testing in their projects.
