Uninitialized constant (NameError) when using FactoryGirl in module

Here's the error I'm getting when I try to run my tests with RSpec:

C:/Ruby193/lib/ruby/gems/1.9.1/gems/activesupport-3.2.11/lib/active_support/infl
ector/methods.rb:230:in `block in constantize': uninitialized constant User (Nam
eError)

I'm trying to run FactoryGirl with RSpec but without Rails. Here are the files that take part in the testing:

user_spec.rb

require 'spec_helper'

module Bluereader
  describe User do
    describe 'login' do
      user = FactoryGirl.build(:user)
    end

    describe 'logout' do

    end

    describe 'create_account' do

    end

    describe 'delete_account' do

    end
  end
end

spec/spec_helper

$LOAD_PATH.unshift(File.join(File.dirname(__FILE__), '..'))
$LOAD_PATH.unshift(File.dirname(__FILE__))

require 'rspec'
require 'lib/bluereader'

require 'factory_girl'
FactoryGirl.find_definitions

spec/factories.rb

require 'digest/sha1'

FactoryGirl.define do
  sequence(:username) { |n| "user-#{n}" }

  factory :user do
    username
    encrypted_password Digest::SHA1.hexdigest('password')
    full_name 'John Doe'
    logged_in_at Time.now
    logged_out_at 0
  end
end

At this point I know that the factories.rb file is being loaded (I tried with the moronic print-debugging). When I remove the user = FactoryGirl.build(:user) line from user_spec.rb I get no errors (and the normal RSpec feedback telling me there are no tests, but no errors). If you are interested, here's my model:

require 'digest/sha1'

module Bluereader
  class User < ActiveRecord::Base
    has_many :categories, :foreign_key => :user_id
    has_many :news, :foreign_key => :user_id
    has_many :settings, :foreign_key => :user_id

    attr_reader :full_name

    class << self
      def login(username, password)
        encrypted_password = Digest::SHA1.hexdigest(password)

        if not User.exists?(:username => username, :encrypted_password => encrypted_password)
          user_id = User.id_from_username(username)
          update(user_id, :logged_in_at => Time.now, :logged_out_at => 0)
        end
      end

      def logout
        update(current_user.id, :logged_out_at => Time.now)
      end

      def validate_account(username, password, full_name)
        if username.empty? or password.empty or full_name.empty?
          return 'Please fill in all the fields.'
        end

        if User.exists?(:username => username)
          return 'That username is already in use.'
        end

        unless username =~ /^\w+$/
          return 'Username field should contain only letters, numbers and underscores.'
        end

        ''
      end

      def create_account(username, password, full_name)
        encrypted_password = Digest::SHA1.hexdigest(password)
        User.create(:username => username,
                    :encrypted_password => encrypted_password,
                    :full_name => full_name,
                    :logged_in_at => Time.now,
                    :logged_out_at => 0)
      end

      def delete_account
        current_user.destroy
      end

      private
      def id_from_username(username)
        user = where(:username => username).first
        user.nil? ? 0 : user.id
      end

      def current_user
        where(:logged_out_at => 0).first
      end
    end
  end
end

SOLUTION

The problem was that the class User was in a module, here's the solution:

factory :user, class: Bluereader::User do

For anyone clumsy like me, you may have FactoryGirl in your code where you meant to have FactoryBot

You need to require the rails environment in your spec helper file. Add the following to spec/spec_helper.rb:

require File.expand_path("../../config/environment", __FILE__)

Update

Even if you're not using Rails, you'll still need to require the models in your spec helper.
