how to impements gem shoulda in unit testing rails 4 without rspec? - ruby-on-rails

Question

how to implements gem shoulda in unit testing without respec?, this is my gemfile file :
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.4'
group :production do
# Use PostgreSQL as the database for Active Record on Heroku
gem 'pg'
end
group :development, :test do
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
gem "minitest"
gem 'byebug'
end
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc
# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
gem 'spring', group: :development
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

# gem 'byebug', group: [:development, :test]
gem 'devise'
gem 'shoulda'
gem 'omniauth-facebook'
gem 'omniauth-google-oauth2'
and this is my test_helper.rb file :
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
include Devise::TestHelpers
require 'minitest/autorun'
require 'shoulda/rails'
class ActiveSupport::TestCase
# Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
fixtures :all
# Add more helper methods to be used by all tests here...
end
this is my example model testing unit :
require 'test_helper'
class UserTest < ActiveSupport::TestCase
should validate_presence_of(:name)
should validate_presence_of(:last_name)
should validate_presence_of(:id_number)
should ensure_inclusion_of(:id_issuing_country).in_array(["Spain"])
should validate_presence_of(:birth_date)
should validate_presence_of(:email)
should validate_presence_of(:bank_account)
end
when i runing this in my console : bin/rake test test/models/user_test.rb
i get error like this :
LoadError: cannot load such file -- shoulda/rails

gem 'capybara'
gem 'database_cleaner'
gem 'shoulda-matchers', '~>2.6.2'
