Rails tutorial chapter 10.3.1 having trouble getting Rspec tests to pass

Question

See the title. Here are my failures, for the life of me I can't figure out why this is failing just before 10.3.2. Before 10.3.1 everything worked fine, and testing the site itself, everything seems OK.

Failures:

  1) Authentication authorization in the Microposts controller submitting to the create action 
     Failure/Error: before { post microposts_path }
     NoMethodError:
       undefined method `sign_in?' for #<MicropostsController:0x007faa8eb32898>

     # ./spec/requests/authentication_pages_spec.rb:106:in `block (5 levels) in <top (required)>'

  2) Authentication authorization in the Microposts controller submitting to the destroy action 
     Failure/Error: before { delete micropost_path(FactoryGirl.create(:micropost)) }
     NoMethodError:
       undefined method `sign_in?' for #<MicropostsController:0x007faa8dc18a88>

Answer 1

check the /app/helpers/sessions_helper.rb

the method must be signed_in? not sign_in?

  def signed_in_user
    unless signed_in?
      store_location
      redirect_to signin_url, notice: "Please sign in."
    end
  end
