I can't get by without redgreen to colorize my test output. You can get it to work with all your Rails test tasks by requiring the redgreen gem in
test_helper.rb. The problem is, it messes up your test output formatting when you run tests in TextMate using Command-R. The solution is trivial - check to see if any of the TextMate execution environment variables are present:
require 'redgreen' unless ENV['TM_MODE']
Now back to your regularly scheduled internets...
