Having learnt about unit testing in rails during my short internship stint at Novell, I've always thought that rake tests would always have colored output. Little did I know that you'd have to install a gem to do so.So, to get your rake test output in a more readable format, install the gem 'redgreen'
gem install redgreenand add the following
require 'redgreen'at the top of your test_helpers.rb.
This would return red/green/yellow colored output on your tests to indicate whether it has passed, has errors or failed. Makes running test much more easy on the eyes :)
