This document summarizes a presentation on the MiniTest testing framework for Ruby. MiniTest is the default testing framework in Ruby 1.9, replacing Test::Unit. It offers less code and more functionality than Test::Unit. The presentation covers the 6 parts of MiniTest, matchers and expectations, MiniTest::Mock, integrations with tools like Rails and Capybara, and resources for learning more.
