The Overlord of Fixtures

Warning!!

Deprecated

Going to provide a rails-esque fixture-mock library

FixtureOverlord

• This is an Alpha version and is currently under heavy development.

Setup

require 'minitest/autorun'

class MiniTest::Unit::TestCase
  # include FixtureOverlord's Mixin
  include FixtureOverlord

  # add the fixture accessor that will define 1 method for each YAML file
  # within {spec,test}/fixtures.
  fixture_overloard :rule # set to :off to not define methods
end

How to use in your Tests

Mocks

class GameTest < MiniTest::Unit::TestCase

  # mock will create an OpenStruct Class with accessors
  # to reference the data.
  #
  # Assuming we have a fixture file named games.yml,
  # and inside that file, we have:
  #
  # tron:
  #   name:    'Tron'
  #   type:    'Video Game'
  #   rating:  'Gold'
  #
  #
  # e.g.
  #   OpenStruct.new(hashed_version_of_yaml_file)
  #
  def test_mock_game
    tron = games(:tron).mock

    assert_equal 'Tron',       tron.name
    assert_equal 'Video Game', tron.tyoe
    assert_equal 'Gold',       tron.rating
  end

end

Use as a plain old hash

class GameTest < MiniTest::Unit::TestCase

  # when a fixture is instantiated, it's a hash with super powers,
  # and it's keys are automatically symbolized.
  #
  # games.yml:
  #
  #   tron:
  #     name:    'Tron'
  #     type:    'Video Game'
  #     rating:  'Gold'
  #
  #
  def test_hash_attributes
    tron = games(:tron)

    assert_instance_of Hashish, tron
    assert_equal 'Tron',       tron[:name]
    assert_equal 'Video Game', tron[:type]
    assert_equal 'Gold',       tron[:rating]
  end

end

Remove Attributes

class GameTest < MiniTest::Unit::TestCase

  # removing attributes
  #
  # games.yml:
  #
  #   tron:
  #     name:    'Tron'
  #     type:    'Video Game'
  #     rating:  'Gold'
  #
  #
  def test_hash_attributes
    tron = games(:tron)

    tron.remove(:name)
    assert_nil tron[:name]
  end

end

Add Attributes

class GameTest < MiniTest::Unit::TestCase

  # adding attributes
  #
  # games.yml:
  #
  #   tron:
  #     name:    'Tron'
  #     type:    'Video Game'
  #     rating:  'Gold'
  #
  #
  def test_hash_attributes
    tron = games(:tron)

    tron.add(likes: 20)
    assert_equal 20, tron[:likes]

    tron = tron.mock
    assert_equal 20, tron.likes
  end

end

Change Attributes

class GameTest < MiniTest::Unit::TestCase

  # adding attributes
  #
  # games.yml:
  #
  #   tron:
  #     name:    'Tron'
  #     type:    'Video Game'
  #     rating:  'Gold'
  #
  #
  def test_hash_attributes
    tron = games(:tron)

    tron.change(rating: 'Silver')
    assert_equal 'Silver', tron[:rating]

    tron = tron.mock
    assert_equal 'Silver', tron.rating
  end
