Pairwise testing is a technique that generates test cases to cover all possible combinations of two test input parameters (2-way) to efficiently find flaws. For an audit testing application with 14 input parameters, traditional testing would require over 18 million test cases, but pairwise testing could cover all 2-way combinations with far fewer test cases, reducing time and effort while still effectively finding 50-90% of flaws.

2. Example

3. 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.

4. n-way combinations
• n = 2, 3, 4, 5, 6
• Focus on testing all possible combinations of
two test inputs (2-way)

5. Benefits of pairwise testing
Total test cases:
> 2^87 = 154.742.504.910.762.534.362.390.528
Pairwise: 16

7. Benefits of pairwise testing
• Tool generates test cases
• Reduce time and effort
• Find flaws efficiently: 50%-90%
