MiniTest is the unit testing library that comes in the Ruby 1.9 standard library and which also acts as a compatibility layer for test/unit on 1.9.

I was frustrated by the lack of documentation and examples on the web so I has put together a handy round up of the assertions and matchers offered by MiniTest::Unit and MiniTest::Spec.

I watch a lot of tests run in a given day. So I figured why not make it more fun. So I created Nyan Cat RSpec Formatter gem. (Includes Screencast)
