Rails Guide

1) Create a new rails app

rails new APP_NAME --skip-test-unit
cd APP_NAME

2) The GEMFILE

source 'https://rubygems.org'

gem 'rails', '3.2.1'
gem 'bcrypt-ruby', '3.0.1'
gem 'faker', '1.0.1'
gem 'will_paginate', '3.0.3'

group :development do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.8.1'
  gem 'guard-rspec', '0.5.5'
  gem 'annotate', '~> 2.4.1.beta'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.3'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.0.3'
end

gem 'jquery-rails', '2.0.0'

group :test do
  gem 'rspec-rails', '2.8.1'
  gem 'capybara', '1.1.2'
  gem 'rb-fsevent', '0.4.3.1', :require => false
  gem 'growl', '1.0.3'
  gem 'guard-spork', '0.3.2'
  gem 'spork', '~> 0.9.0.rc'
  gem 'factory_girl_rails', '1.4.0'
  gem 'cucumber-rails', '1.2.1'
  gem 'database_cleaner', '0.7.0'
end

group :production do
  gem 'pg', '0.12.2'
end





3) Installer les dépendances de l'environnement de dev et de tests (pas besoin de l'env de prod)

bundle install --without production


4) Gérer les tests RSpec

rails generate rspec:install


5) Integrer Bundler (pour éviter les bundle exec)

rvm get head && rvm reload
chmod +x $rvm_path/hooks/after_cd_bundler
bundle install --without production --binstubs=./bundler_stubs

6) Initialiser guard

guard init rspec

7) Ajout au Guardfile

require 'active_support/core_ext'

guard 'rspec', :version => 2, :all_after_pass => false do
  .
  .
  .
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  do |m|
    ["spec/routing/#{m[1]}_routing_spec.rb",
     "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb",
     "spec/acceptance/#{m[1]}_spec.rb",
     "spec/requests/#{m[1].singularize}_pages_spec.rb"]
  end
  watch(%r{^app/views/(.+)/}) do |m|
    "spec/requests/#{m[1].singularize}_pages_spec.rb"
  end
  .
  .
  .
end

8) Relancer binstubs

bundle --binstubs=./bundler_stubs

9) Spork

spork --bootstrap

10) spec/spec_helper.rb

require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However, 
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.
  # This file is copied to spec/ when you run 'rails generate rspec:install'
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'

  # Requires supporting ruby files with custom matchers and macros, etc,
  # in spec/support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    # == Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr
    config.mock_with :rspec

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, remove the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    # If true, the base class of anonymous controllers will be inferred
    # automatically. This will be the default behavior in future versions of
    # rspec-rails.
    config.infer_base_class_for_anonymous_controllers = false
  end
end

Spork.each_run do
  # This code will be run each time you run your specs.

end

# --- Instructions ---
# Sort the contents of this file into a Spork.prefork and a Spork.each_run
# block.
#
# The Spork.prefork block is run only once when the spork server is started.
# You typically want to place most of your (slow) initializer code in here, in
# particular, require'ing any 3rd-party gems that you don't normally modify
# during development.
#
# The Spork.each_run block is run each time you run your specs.  In case you
# need to load files that tend to change during development, require them here.
# With Rails, your application modules are loaded automatically, so sometimes
# this block can remain empty.
#
# Note: You can modify files loaded *from* the Spork.each_run block without
# restarting the spork server.  However, this file itself will not be reloaded,
# so if you change any of the code inside the each_run block, you still need to
# restart the server.  In general, if you have non-trivial code in this file,
# it's advisable to move it into a separate file so you can easily edit it
# without restarting spork.  (For example, with RSpec, you could move
# non-trivial code into a file spec/support/my_helper.rb, making sure that the
# spec/support/* files are require'd from inside the each_run block.)
#
# Any code that is left outside the two blocks will be run during preforking
# *and* during each_run -- that's probably not what you want.
#
# These instructions should self-destruct in 10 seconds.  If they don't, feel
# free to delete them.
