AllPairs is a test combinations generator that allows to create set of tests using 'pairwise combinations' method, which reduces a number of combinations of variables into a lesser set which covers most situations.

What's good:

• Free and Open-Source.
• Produces good enough dataset.
• Good set of useful features:
  • Developer-friendly, Iterator style for use in your scripts.
  • Allows to filter out "invalid" combinations during search for the next combination.
  • Allows to exclude "previously tested" pairs/combinations.
  • Goes beyond pairs! If/when required can generate n-wise combinations.

What's not perfect:

• Not optimal - there are tools that can create smaller set covering all the pairs. However they are missing some other important features.
• Lousy written filtering function may lead to full permutation of parameters.
• v.2 has become slower (as result of possibility to produce n-wise combinations)
• No warranty ;)

History:

• v.1 was developed at May, 2002 and was widely used in MetaCommunications Inc. for multiple testing projects.
• v.2 was developed at September, 2007 and published at the January of 2008.
