+# Colorful Output With MiniTest
+
+Ruby's
+[`MiniTest`](http://ruby-doc.org/stdlib-2.0.0/libdoc/minitest/rdoc/MiniTest.html)
+is a minimal testing framework that you can easily drop-in to any Ruby
+project. For those used to using [`RSpec`](http://rspec.info/) with it's fancy
+red/green output, MiniTest can be a little disappointing. It prints boring,
+uncolored text to the screen that lacks visual feedback. Fortunately, red
+and green coloring can be added with
+[`minitest/reporters`](https://github.com/kern/minitest-reporters).
+
+Update your `Gemfile`:
+
+```ruby
+gem 'minitest-reporters'
+```
+
+Then require and configure `minitest-reporters` in your testing setup file
+(e.g. `test/test_helper.rb`):
+
+```ruby
+require 'minitest/reporters'
+Minitest::Reporters.use! [Minitest::Reporters::DefaultReporter.new(:color => true)]
+```
+
+You can now enjoy that Red, Green, Refactor cycle.
