Rails Tutorial 9.3 failed test updating User authentication - ruby-on-rails

Question

I am having a problem with the Rails Tutorial (rails 3). I'm currently on 9.28 rSpec tests and I have been in constant search to figure out what I did to make these two errors.
user#ubuntu:~/rails_projects/sample_app$ bundle exec rspec spec/
......................F.F............................................
Failures:
1) Authentication authorization in the Users controller visiting the edit page
Failure/Error: before { visit edit_user_path(user) }
NameError:
undefined local variable or method `user' for #<RSpec::Core::ExampleGroup::Nested_3::Nested_3::Nested_2::Nested_1:0x9685354>
# ./spec/requests/authentication_pages_spec.rb:75:in `block (5 levels) in <top (required)>'
2) Authentication authorization in the Users controller submitting to the update action
Failure/Error: before { put user_path(user) }
NameError:

rspec ./spec/requests/authentication_pages_spec.rb:76 # Authentication authorization in the Users controller visiting the edit page
rspec ./spec/requests/authentication_pages_spec.rb:86 # Authentication authorization in the Users controller submitting to the update action
This is the authentication spec:
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_selector('title', text: full_title('Sign in')) }
end
describe "signin" do
before { visit signin_path }
describe "with invalid information" do
before{ click_button "Sign in" }
it { should have_selector('title', text: full_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 "valid information" do
let (:user) { FactoryGirl.create(:user) }
before { sign_in user }
it { should have_selector('title', text: full_title(user.name)) }
it { should have_link('Users', href: users_path) }
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) }
it { should_not have_link('Sign in', href: signin_path) }
describe "followed by signout" do
before { click_link "Sign out" }
it { should have_link('Sign in', href: signin_path) }
end
end
end
describe "authorization" do
describe "for non-signed-in users" do
let(:user) { FactoryGirl.create(:user) }
describe "when attempting to visit a protected page" do
before do
visit edit_user_path(user)
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
describe "after signing in" do
it "should render the desired protected page" do
expect(page).to have_selector('title', text: ('Edit user'))
end
end
end
end
describe "in the Users controller" do
describe "visiting the edit page" do
before { visit edit_user_path(user) }
it { should have_selector('title', text: full_title('Sign in')) }
end
describe "visiting the user index" do
before { visit users_path }
it { should have_selector('title', text: full_title('Sign in')) }
end
describe "submitting to the update action" do
before { put user_path(user) }
specify { response.should redirect_to(signin_path) }
end
end
describe "as wrong user" do
let(:user) { FactoryGirl.create(:user) }
let(:wrong_user) { FactoryGirl.create(:user, email: "wrong#example.com") }
before { sign_in user, no_capybara: true }
describe "submitting a GET request to the Users#edit action" do
before { get edit_user_path(wrong_user) }
specify { expect(response.body).not_to match(full_title('Edit user')) }
specify { expect(response).to redirect_to(root_url) }
end
describe "submitting a PUT request to the Users#update action" do
before { put user_path(wrong_user) }
specify { expect(response).to redirect_to(root_url) }
end
end
end
end
Really I have been trying to figure this out for quite sometime, if it is possible to walk through explanation ( if it is not typo ) would be awesome. Starting to grasp Rails but not quite there.

Answer 1

If you reindent the messy spec code, you can see that you are missing the user definition in your describe "in the Users controller" block.
Seeing that you are using the user in all three describe blocks in the Authorization, I'd move it one level up, so you'll end up with:
describe "authorization" do
let(:user) { FactoryGirl.create(:user) }
describe "for non-signed-in users" do
...
end
describe "in the Users controller" do
...
end
describe "as wrong user" do
let(:wrong_user) { FactoryGirl.create(:user, email: "wrong#example.com") }
before { sign_in user, no_capybara: true }
...
end
end
