ruby 1.9.3 - Rspec test issue not producing proper response -

i receive following response when try run rspec tests.

user.respond_to?(:name)

should "true" following error instead

(added)    **nameerror: undefined local variable or method `user' main:object (irb):2 /users/mwsage/.rvm/gems/ruby-1.9.3-p429@rails3tutorial2nded/gems/railties-3.2.13/lib/rails/commands/console.rb:47:in `start' /users/mwsage/.rvm/gems/ruby-1.9.3-p429@rails3tutorial2nded/gems/railties-3.2.13/lib/rails/commands/console.rb:8:in `start' /users/mwsage/.rvm/gems/ruby-1.9.3-p429@rails3tutorial2nded/gems/railties-3.2.13/lib/rails/commands.rb:41:in `<top (required)>' script/rails:6:in `require' script/rails:6:in `<main>' 

instead of receiving "true" or "false" response. ideas?

from gemfile gem 'rails', '3.2.13' gem 'rspec-rails', '2.11.0' ruby '1.9.3'

here exact test , erro hartl tutorial 6.2.2 validating presence

user = user.new(name: "", email: "mhartl@example.com") >> user.save => false 

*false response supposed get, error above receive.

here user.rb file

class user < activerecord::base    attr_accessible :name, :email    validates :name, presence: true end 

here user_spec.rb file

require 'spec_helper'  describe user     before { @user = user.new(name: "example user", email: "user@example.com") }     subject { @user }    { should respond_to(:name) }   { should respond_to(:email) } end
