pairwise-test-coverage

Pairwise testing reduces combinatorial explosion by covering all interactions between factors with near-minimal test cases. It ensures reliable defect detection across multi-parameter configurations without requiring exhaustive test suites.

You can generate a pairwise test matrix by running a greedy algorithm on your factor set. The generator outputs a minimal test matrix covering all 2-wise or 3-wise interactions, exportable as markdown tables or TypeScript test-case snippets.

Yes, pairwise test generation works for state machine testing and fault injection matrices. The technique applies to any scenario involving 3 or more interacting parameters where you need near-minimal test cases ensuring full coverage.

The best way to validate combinatorial test matrix coverage is using validation utilities that verify full 2-wise or 3-wise factor interactions and compute your matrix size. This ensures all required parameter interactions are tested.

Limitations of pairwise testing include enforced practical limits of a maximum of 20 factors and 50 values per factor. These constraints ensure the greedy algorithm generates test matrices efficiently without exceeding processing capabilities.
