`(3 niveaux) dans <top (obligatoire)> »

Question

Exécution quelques tests et d'obtenir la même erreur sur chaque élément:

Failures: 

    1) Register Frozen Pizza should be $5.00 each 
    Failure/Error: expect(subject.total).to eq 5.00 

     expected: 5.0 
      got: {"Frozen Pizza"=>1} 

     (compared using ==) 
    # ./register_spec.rb:11:in `block (3 levels) in <top (required)>' 

    2) Register Corn should be $0.50 each 
    Failure/Error: expect(subject.total).to eq 0.50 

     expected: 0.5 
      got: {"Corn"=>1} 

     (compared using ==) 
    # ./register_spec.rb:20:in `block (3 levels) in <top (required)>' 

Aucune idée de ce qui cause ces 16 erreurs. Voici une partie du fichier Spec:

require 'register' 

require 'timecop' 

describe Register do 
    subject { described_class.new } 

    describe 'Frozen Pizza' do 
    it 'should be $5.00 each' do 
     subject.ring_up('Frozen Pizza', quantity: 1) 
     expect(subject.total).to eq 5.00 
     subject.ring_up('Frozen Pizza', quantity: 1) 
     expect(subject.total).to eq 10.00 
    end 
    end 

    describe 'Corn' do 
    it 'should be $0.50 each' do 
     subject.ring_up('Corn', quantity: 1) 
     expect(subject.total).to eq 0.50 
    end 
    it 'should be 5 for $2.00' do 
     subject.ring_up('Corn', quantity: 5) 
     expect(subject.total).to eq 2.00 
     subject.ring_up('Corn', quantity: 1) 
     expect(subject.total).to eq 2.50 
    end 
    end 

I Comprise parties de la spécification, mais si je dois je modifier le code complet.

fichier Register.rb:

class Register 
    attr :items 

    def initialize 
    @items = Hash.new(0) 
    end 

    def ring_up(item, args) 
    @items[item] += args[:quantity] 
    end 

    def total 
    total = 0 
    items.each do |item, quantity| 
     case item 
     when 'Frozen Pizza' 
     total += quantity * 5.00 
     when 'Corn' 
     if (quantity % 5 == 0) 
      total += quantity/5 * 2.00 
     else 
      bundles = quantity/5 
      singles = quantity % 5 
      total += bundles * 2.00 + singles * 0.50 
     end 
     when 'Ground Beef' 
     total += (quantity * 4.99).round(2) 
     when /Mayfield Ice Cream/ 
     if (quantity % 2 == 0) 
      if item =~ /^Chocolate/ 
      if Time.now.strftime("%A") == 'Wednesday' 
       total += quantity/2 * 5.99 
      else 
       total += quantity * 5.99 
      end 
      else 
      total += quantity * 5.99 
      end 
     else 
      if item =~ /^Chocolate/ 
      if Time.now.strftime("%A") == 'Wednesday' 
       total += (quantity/2) * 5.99 + (quantity % 2) * 5.99 
      else 
       total += quantity * 5.99 
      end 
      else 
      total += quantity * 5.99 
      end 
     end 
     when 'Mango' 
     if Time.now.strftime("%A") == 'Monday' 
      total += quantity * 0.50 
     else 
      total += quantity * 1.00 
     end 


#Additions 

     when 'Mahi Fillet' 
     total += quantity * 7.99 
     when 'Mac & Cheese' 
     if (quantity % 10 == 0) 
      total += quantity/10 * 1.00 
     else 
      total += quantity/1 * 1.29 
     end 



    end 
    total 
    end 

    end 
end 

Answer 1

Il est difficile de voir, parce que cette méthode est très longue et l'empreinte est pas claire, mais vous devez déplacer le total que vous voulez revenir dans le dernier ligne de la méthode total. Changer

end 
    total 
    end 

    end 
end 

à:

 end 
    end 
    total 
    end 

end
