Colorize MiniTest Output

I use MiniTest all the time for my hobby Ruby projects. I like its simple syntax and easy setup.

The test output can be a little sparse. Today I learned that it's easy to colorize the output of MiniTest, just like the defaults in more heavyweight test frameworks.

Add this to your Gemfile:

gem 'minitest-rg'

Then require the package in any test:

# test/my_test.rb

require 'minitest/rg'

Now we get a nice red, green, yellow colorized output.

minitest-rg
