I am trying to follow TDD on Rails Tutorial which is available online here

While testing first app, I got an error.

My spec.rb code is this:

require 'spec_helper'

describe "Static pages" do
describe "Home page" do

it "should have the content 'Sample App'" do
  visit '/static_pages/home'
  page.should have_content('Sample App')
end
end
end

After running testing I got this error:

Failure/Error: visit '/static_pages/home'
 NoMethodError:
   undefined method `visit' for #    <RSpec::Core::ExampleGroup::Nested_1::Nested_1:0xa833e5c># ./spec/requests/static_pages_spec.rb:8:in `block (3 levels) in <top (required)>'

I will really appreciate your help.
