MiniTest: Refactoring Test Unit and RSpec back to version 0.0.1
summary
MiniTest presents a tiny, readable test framework that ships with Ruby 1.9 and Rails 4 and serves as a drop-in replacement for Test::Unit while reproducing RSpec-style expectations by using infect_an_assertion to map assertions to spec-like methods. The mock library is about 100 lines and stubbing relies on per-object singleton methods; tests run in random order by default, minitest-pride colorizes output, and one refactor example deletes 72 lines and replaces them with six.
