Pairwise Testing

Generate pairwise (all-pairs) test combinations to reduce test cases while maintaining coverage.

What is Pairwise Testing?

Pairwise testing covers all possible pairs of input parameter values. Research shows most software defects are caused by interactions between just 2 parameters.

How to use Pairwise Testing Generator?

  1. Add parameters (e.g., Browser, OS, Language)
  2. Add values for each parameter (e.g., Chrome, Firefox, Safari)
  3. Click Generate to create the minimal test set
  4. Export the test cases to use in your test plan

When to use pairwise testing

Use pairwise testing when you have many parameters with multiple values and cannot test all combinations. It reduces test cases from thousands to dozens while maintaining coverage.
