ALLPAIRS

ALLPAIRS is a command-line tool by James Bach that generates a small set of test cases satisfying all-pairs coverage: each value of each variable is combined with each value of every other variable at least once. It is intended for configuration testing and other situations with many variables, where testing every combination is not practical.

The tool is an executable built from a Perl script; the source is included in the download. It is distributed free of charge from the Satisfice website, without stated licence terms. The download page was last updated in June 2023.
