All Pairs

All Pairs is a Windows tool for creating test cases when a system has many configurable variables. It addresses situations where each variable can have several possible values, making complete combination testing impractical. Its purpose is to produce a smaller group of tests that still covers interactions between pairs of values.

The tool pairs each value of one variable with each value of every other variable at least once. This approach focuses testing on two-variable interactions rather than requiring every possible combination across all variables. All Pairs finds a reasonably small set of test cases that meets this pair-coverage standard.

It can be used for configuration testing involving variables such as printers, print options, and documents. It is intended for people who need to plan systematic tests without manually examining every combination. The resulting cases provide a structured basis for checking which combinations work or fail.

As a Windows product, All Pairs fits the software tools category for test planning and configuration analysis on that platform.
