Pairwise testing , also known as all-pairs testing is the method of finding defects by using a combinational method of two test cases. It relies on the observation that most defects are caused by interaction of at most two factors. For Example, If we have to test the below test scenarios and to generate combinatorial test ideas. I recently encountered a new tool, "AllPairspy" Step 1: Online Tool for Combinatorial Test Case Generation It is very easy tool, a single page application with How to Use.
