Bootstrap new rails project

gistfile1.md

Setup new rails 3 project with rspec, factory_girl, guard and spork

Init Rails project

rails new APP_NAME --skip-bundle --skip-test-unit

The Gemfile - pry, rspec, factory_girl, capybara, guard, shoulda and spork

gem 'pry-rails', group: :development  
  
group :development, :test do  
  gem 'debugger'  
  gem 'rspec-rails'  
  gem 'jasminerice'  
  gem 'launchy'  
end  
  
group :test do  
  gem "factory_girl_rails"  
  gem "capybara"  
  gem 'shoulda-matchers'  
  gem "guard-rspec"  
  gem "spork-rails"  
  gem "guard-spork"  
end  

Setup gems

bundle install # --without=production  
rails g rspec:install  
mkdir spec/support spec/models spec/routing spec/requests  
touch spec/{support,models,routing,requests}/.gitkeep  
guard init rspec  
spork --bootstrap  
guard init spork

Prepare spec_helper

require 'rubygems'
require 'spork'

Spork.prefork do
  require "rails/application"

  Spork.trap_method(Rails::Application, :reload_routes!)
  Spork.trap_method(Rails::Application::RoutesReloader, :reload!)

  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'

  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    config.mock_with :rspec

    config.use_transactional_fixtures = false
  end
end

Spork.each_run do
  FactoryGirl.reload
end

Tune guard file

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, :rspec_env => { 'RAILS_ENV' => 'test' } do
  watch('config/application.rb')
  watch('config/environment.rb')
  watch('config/environments/test.rb')
  watch(%r{^config/initializers/.+\.rb$})
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('spec/spec_helper.rb') { :rspec }
  watch('test/test_helper.rb') { :test_unit }
  watch(%r{features/support/}) { :cucumber }
end

guard 'rspec', :version => 2, :cli => '--drb' do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$})          { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }
  
  # Capybara request specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml)$})          { |m| "spec/requests/#{m[1]}_spec.rb" }
  
  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }
end  

Example spec/factories.rb file

FactoryGirl.define do
  factory :user do
    sequence :username do |n|
      "jack#{n}"
    end

    sequence :email do |n|
      "jack#{n}@example.com"
    end

    password 'secret'
  end
end

Add version control

git init  
git remote add origin REPO_END_POINT
git add -A . 
git commit -a -m 'initial commit'
git push -u origin master
