Rails Tests Not Found - Undefined local variable or method "response" - ruby-on-rails-3

Question

I'm trying to follow Michael Hartl's Rails 3 tutorial and I'm running into an error I can't find explained elsewhere. Under Section 9.2.1, I'm getting an error when trying to run a test for non-signed-in users trying to update a profile page.
describe "submitting to the update action" do
before { put user_path(user) }
specify { response.should redirect_to(signin_path) }
end
The error I'm getting is "undefined local variable or method 'response' for # (NameError)". This is a response to "bundle exec rspec spec/". When I comment out the offending line, all tests instantiate and pass. I've tried replacing "response" with things like "response.body" and "page" but neither seem to help.
I'm not sure what the issue is because as I'm moving forward with the tutorial, similar blocks are passing without incident.
Here's the full error text:

I'm pretty sure it's not a typo somewhere but here's the offending file (authentication_pages_spec.rb). (have_title() is a method I found here for fixing an error because apparently have_selector('title',...) is no longer valid syntax.)
require 'spec_helper'
describe "Authentication" do
subject { page }
describe "signin page" do
before { visit signin_path }
it {should have_selector('h1', text: 'Sign in') }
it {should have_title('Sign in') }
end
describe "signin" do
before { visit signin_path }
describe "with invalid information" do
before { click_button "Sign in" }
it { should have_title('Sign in') }
it { should have_selector('div.alert.alert-error', text: 'Invalid') }
describe "after visiting another page" do
before { click_link "Home" }
it { should_not have_selector('div.alert.alert-error') }
end
end
describe "with valid information" do
let(:user) { FactoryGirl.create(:user) }
before { sign_in user }
it { should have_title(user.name) }
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Settings', href: edit_user_path(user)) }
it { should have_link('Sign out', href: signout_path) }

Answer 1

What version of Capybara are you running?
$ bundle exec gem list | grep capybara
If you're running version >= 2.0 you should look again at your Gemfile and specifically mark the version to be the same as the tutorial (1.1.2).
Gemfile
group :test do
gem 'capybara', '1.1.2'
end
If you desperately want to use the latest version, you'll have to make some changes, outlined in the following StackOverflow Q&As:
Capybara methods are undefined
capybara: post, get methods not working when changing name of requests directory to features
RSpec & Capybara 2.0 tripping up my have_selector tests
Update
Okay, you're going to kick yourself, but after cloning your repo and getting the same error, your problem is obvious (syntax highlighting is your friend):
On Line 77 of your spec/requests/authentication_pages_spec.rb you have:
specify ( response.should redirect_to(signin_path) )
It should be:
specify { response.should redirect_to(signin_path) }
After fixing that, your tests will pass.
