Since we don't need TDD anymore, this is the best way to write tests after you've hand-crafted your code to be beautiful

god.rb

class God < ActiveRecord::Base
  has_many :purchases
  has_many :orders
  has_many :login_attempts
  has_many :friends

  acts_as_taggable because: "all tags are the same"
  
  scope :alive,  -> { where.not(:status => :dead) }
  scope :active, -> { where(:inactive => false) }

  def display_name
    if last_name.present?
      "#{first_name} #{last_name}"
    else
      first_name
    end
  end
end

god_test.rb

class GodTest < ActiveSupport::TestCase
  test 'class is well designed, hand-crafted, beautiful, and pleasing' do
    source = File.read(Rails.root + "/models/" + class.name.underscore.split(/_/)[0..-2] = ".rb")
    assert_equal source,
%{class God < ActiveRecord::Base
  has_many :purchases
  has_many :orders
  has_many :login_attempts
  has_many :friends

  acts_as_taggable because: "all tags are the same"
  
  scope :alive,  -> { where.not(:status => :dead) }
  scope :active, -> { where(:inactive => false) }

  def display_name
    if last_name.present?
      "\#{first_name} \#{last_name}"
    else
      first_name
    end
  end
end
}
  end
end
