Question

Estoy intentando pasar mis especificaciones del modelo para la validación pero no puedo hacer que pasen. He colocado todas las reglas de validación en mi archivo de modelo también

app / model / user.rb

class User < ActiveRecord::Base
  has_many :friendships
  has_many :friends, :through => :friendships
  has_many :plans
  has_many :memberships, class_name: "PlanMemebership"
  has_many :notes
  has_many :replies, class_name: "NoteReply"
  has_many :upvotes, class_name: "NoteUpvote"

  validates :first_name, presence: true
  validates :last_name, presence: true
  validates :email, presence: true
  validates :facebook_user_id, presence: true, uniqueness: true
  validates :facebook_user_token, presence: true, uniqueness: true
  validates :token, presence: true, uniqueness: true
  validates :birthday, presence: true
  validates :gender, presence: true

  def name
    first_name + " " + last_name
  end

end

especificaciones / modelos / user_spec.rb

require ''rails_helper''

describe User, :type => :model do

  context "valid Factory" do
    it "has a valid factory" do
      expect(FactoryGirl.build(:user)).to be_valid
    end
  end

  context "validations" do
    it { should validate_presence_of :first_name }
    it { should validate_presence_of :last_name }
    it { should validate_presence_of :email }
    it { should validate_presence_of :birthday }
    it { should validate_presence_of :gender }
    it { should validate_presence_of :facebook_user_id }
    it { should validate_presence_of :facebook_user_token }

    context "uniqueness" do
      before { create(:user) }
      it { should validate_uniqueness_of :facebook_user_id }
      it { should validate_uniqueness_of :facebook_user_token }
      it { should validate_uniqueness_of :token }
    end
  end
end

spec / factories / users.rb

FactoryGirl.define do
  sequence(:facebook_id) { |n| "#{n}1004453333331" }
  sequence(:facebook_user_token) { |n| "#{n}CAA" + ("X" * 216) }

  factory :user do
    first_name "Ralph"
    last_name "Robot"
    email "[email protected]"
    facebook_user_id { generate(:facebook_id) }
    facebook_user_token

    birthday { Date.current }
    gender "Male"

    token { Token.new.generate }
  end

end

Salida de prueba

Token
  #generate
    returns a 20-byte token

User
  valid Factory
    has a valid factory

Answer 1

Agrega rspec-rails y shoulda-matchers en tu Gemfile :

group :development, :test do
  gem ''rspec-rails'', ''~> 3.4'', ''>= 3.4.2''
  gem ''shoulda-matchers'', ''~> 3.1'', ''>= 3.1.1''
end

Establezca su spec/rails_helper.rb para usar rspec-rails y shoulda-matchers :

require ''rspec/rails''
require ''shoulda/matchers''

Y agregue su spec/spec_helper.rb :

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :rspec
    with.library :rails
  end
end

Answer 2

Creo que debes agregar lo siguiente a tu spec_helper.rb

require ''shoulda/matchers''

Sus especificaciones están perdiendo los métodos de shoulda matcher.

Aquí está la fuente. Puedes comprobar. La gente se queja cosas similares. https://github.com/thoughtbot/shoulda-matchers/issues/384
