Cucumber is a behaviour driven development tool written in Ruby, and primarily (but not exclusively) for use in Ruby.

I'm logging this largely for the record - Cucumber comes as a Ruby Gem and easily installs.

Here's the help message after install

  WomanWithCat:cuc grahamellis$ cucumber --help

  Usage: cucumber [options] [ [FILE|DIR|URL][:LINE[:LINE]*] ]+

  

  Examples:

  cucumber examples/i18n/en/features

  cucumber @rerun.txt (See --format rerun)

  cucumber examples/i18n/it/features/somma.feature:6:98:113

  cucumber -s -i http://rubyurl.com/eeCl

  etc ... all options listed!

First use turns out to be not quote so simple - you need to specify a behaviour, then code that tests that behaviour, then the class / code that implements that behaviour. Easy if you're lead through it on one of our Ruby courses or you might like to take the very first steps from [here]
