Based on the EdgeCase Ruby Koans this is a conversion of the exercises. Some of the Ruby tests are removed since they are not possublein groovy and others are added since they are not possible in Ruby.
Install Groovy:
http://groovy.codehaus.org/
Retrieve this project.
git clone git@github.com:esumerfd/Groovy-Koans.git
If you have gradle then
gradle
If you do not then just run the as groovy file.
groovy org/bitbashers/koans/PathToEnlightenmant.groovy
Good luck.
