+framework called minitest (Or TestUnit for ruby version 1.8.x). There are many
+testing libraries with different goals.
+
+* TestUnit - Ruby 1.8's built-in "Unit-style" testing framework
+* minitest - Ruby 1.9/2.0's built-in testing framework
+* RSpec - A testing framework that focuses on expressivity
+* Cucumber - A BDD testing framework that parses Gherkin formatted tests
