Question

I would like to have unit tests output color in my dev environment. However, I can\'t make it work on Linux (Debian and Ubuntu). When I include the following libs:

Answer 1

simply add these lines to your test_helper.rb file after require 'rails/test_help'

require "minitest/reporters"
Minitest::Reporters.use!

in your gemfile add

gem 'minitest-reporters', '~> 1.0.7'

this will get your rake test to be in red and green, but it also brings up the backtrace. to get rid of all those extra backtrace logs add this to your gemfile then bundle:

gem 'mini_backtrace'

then in config/initializers/backtrace_silencers.rb add this line to cut all the extra rvm stuff

Rails.backtrace_cleaner.add_silencer { |line| line =~ /rvm/ }

hope that works for you, let me know if you need more details.
