Pairwise testing is an effective test case generation technique that is based on the observation that most faults are caused by interactions of at most two factors. Pairwise-generated test suites cover all combinations of two therefore are much smaller than exhaustive ones yet still very effective in finding defects.

### Tools
There are many [tools](./tools.md) that adopted and integrated pairwise testing as one of the test generation methods.
