Ruby Koans

Simply a set of unit test files which are executed in a certain order and initially all fail. The unit test runner directs you to which file to fix next.

Ensure you have ruby, download the zip file of koans from http://rubykoans.com/ and run ruby path_to_enlightenment.rb inside the directory to execute the test runner.

34 files in total consisting of 282 tests.
