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

Try this line. In the describe block and it should fail.

people(:one).name.must_equal 'America!'

This won't work on 1.8 with Rails 3.2. You can get full-ish integration on 1.8 with Rails 3.2 simply by doing Gem.activate 'minitest_tu_shim' before require 'rails/test_help'. You'll need the 'minitest_tu_shim' gem, which ideally you want to include with :platforms => :mri_18 in your Gemfile.

The gem name is now https://github.com/metaskills/minitest-spec-rails
