  1. Shoulda: with vs. without

    ActiveRecord spec without shoulda:

    describe Address do
  let(:address) { Factory.build :valid_address }
  %w(street_address locality region postal_code country).each do |attribute|
    it "is invalid without #{attribute}" do
      address.send "#{attribute}=", nil
      address.should_not be_valid
      address.errors.on(:"#{attribute}").should include "can't be blank"
      address.send "#{attribute}=", 'valid input'
     address.should be_valid
    end
  end
end

    ActiveRecord spec with Shoulda:

    describe Address do
  it { should validate_presence_of :street_address }
  it { should validate_presence_of :locality }
  it { should validate_presence_of :region }
  it { should validate_presence_of :postal_code }
  it { should validate_presence_of :country_name }
end

    Even using a healthy dash of metaprogramming to make the first example as brief as possible, it’s clear shoulda wins hands down for brevity, readability, and concision.
