Abstract— Software testing efficiency is very important factor for all test organizations. By conducting case studies in various test environments, this paper is proving that we can improve the testing efficiency of the test organization using combinatorial test design techniques (CTD) and also showing the benefits of applying a formal tool aided test design technique to come up with an optimized test plan.

I. INTRODUCTION

Various studies conducted in testing industry showing the importance of testing combination of input variables that affecting common output. Some of the studies concluded that variable interactions are common cause of multi-modal bugs in software. An exhaustive kind of testing using all combination of input variable is not practical in all cases. So how do we derive a suitable set of test cases when it’s just not feasible to use all the possible combinations and variations of test parameters? The article is trying to address…
