Michael Hartl's Rails Tutorial Exercise 8.1 Rspec Failures

Question

I'm a Rails newbie working my way through Michael Hartl's latest Rails Tutorial. I'm running Ruby 2.0.1 and Rails 4.0.

When testing for Authentication my Rspec returns the following errors.

I apologize in advance if my post is not detailed enough, please let me know if there is anything else I can include to help crack this problem.

I appreciate everyones time.

Thanks!

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  # root to: 'welcome#index'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end
  #
  #     collection do
  #       get 'sold'
  #     end
  #   end

  # Example resource route with sub-resources:
  #   resources :products do
  #     resources :comments, :sales
  #     resource :seller
  #   end

  # Example resource route with more complex sub-resources:
  #   resources :products do
  #     resources :comments
  #     resources :sales do
  #       get 'recent', on: :collection
  #     end
  #   end

  # Example resource route within a namespace:
  #   namespace :admin do
  #     # Directs /admin/products/* to Admin::ProductsController
  #     # (app/controllers/admin/products_controller.rb)
  #     resources :products
  #   end
end

Thanks I really appreciate your answer. After adding the click_button "Sign in" line I began to receive the following errors when I run Rspec.

Answer 1

After you fill in email and password, you also need to click that button in "with valid infomration" example so the form is submitted and the next page is rendered.

describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before do
        visit signin_path
        fill_in "Email",    with: user.email.upcase
        fill_in "Password", with: user.password
        click_button "Sign in"   # <------------------- Add this line
      end
      it { should have_title(user.name) }
      it { should have_link('Profile',     href: user_path(user), visible: false) }
      it { should have_link('Sign out',    href: signout_path) }
      it { should_not have_link('Sign in', href: signin_path) }
end
