Use minitest/spec with Rails 3

person_test.rb

require 'test_helper'
require 'minitest/autorun'

module Tenderlove
  class Spec < MiniTest::Spec
    include ActiveSupport::Testing::SetupAndTeardown
    include ActiveRecord::TestFixtures

    alias :method_name :__name__ if defined? :__name__
    self.fixture_path = File.join(Rails.root, 'test', 'fixtures')
  end
end

class PersonTest < Tenderlove::Spec
  fixtures :people

  describe 'holy shit' do
    it 'does awesome stuff' do
      1.must_equal 1
    end
  end

  it 'finds a fixture' do
    people(:one).name.must_equal 'America!'
  end
end
