PAIRWISE TESTING

Example

What is pairwise testing?

• Pairwise Testing also known as all-pairs testing is a testing approach taken for testing the software using combinatorial method for two test inputs.

n-way combinations

• n = 2, 3, 4, 5, 6• Focus on testing all possible combinations of

two test inputs (2-way)

Benefits of pairwise testing

• Tool generates test cases• Reduce time and effort• Find flaws efficiently: 50%-90%
