# Crystalball

Crystalball is a Ruby library which implements [Regression Test Selection mechanism](https://tenderlovemaking.com/2015/02/13/predicting-test-failues.html) originally published by Aaron Patterson.
Its main purpose is to select a minimal subset of your test suite which should be run to ensure your changes didn't break anything.
