Classic RSpec vs rspec-given

# Classic Rspec Style

describe User do
  before(:each) do
    @user = User.new
  end

  describe '#last_login' do
    it 'should return the last login record for the user if there is one' do
      # given
      logins = []
      3.times do |i|
        logins << Login.new(:auth_hash => i)
      end

      @user.stub!(:logins).and_return(logins)

      # expect
      @user.last_login.should == logins.first

    end
  end
end

# Same with rspec-given sugar.
