Test::Unit::TestCase

This extension of the standard Test::Unit::TestCase makes RSpec available from within, so that you can do things like:

require ‘spec/test/unit’

class MyTest < Test::Unit::TestCase

  it "should work with Test::Unit assertions" do
    assert_equal 4, 2+1
  end

  def test_should_work_with_rspec_expectations
    (3+1).should == 5
  end

end
