This is a library for "shrinking" failure cases. All the major QuickCheck-like testing libraries use a similar approach. I am building Midje support for generative testing, and in the process noticed that test.generative doesn't shrink and (at least at the time) ClojureCheck didn't either. Thus I decided a library like this might be of some general purpose use to the test-library writers in the community.
As usual feedback, and involvement in the project are welcome.
Best,
Alex
