Install Rails

gem install rails

generate new app, skipping Test::Unit file generation

rails new my_app -T

Set up Gemfile

gem 'jquery-rails'
gem 'haml-rails'
gem 'simple_form'

group :development do
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'meta_request' #https://github.com/dejan/rails_panel
end


group :test, :development do
  gem "rspec-rails"
  gem 'rspec-instafail'
  gem 'rb-fsevent'
  gem 'growl'
  gem 'pry'
  gem 'factory_girl_rails'
  gem 'database_cleaner'
  gem "factory_girl_rails"
  gem "capybara"
  gem 'guard-spork'
  gem "guard-bundler"
  gem "guard-rspec"
  gem "guard-migrate"
  gem 'awesome_print'
end

Install our gems, and scope them to our app

bundle install --path vendor

Use this for all subsequent ````bundle install``` commands. Why? http://ryan.mcgeary.org/2011/02/09/vendor-everything-still-applies/

Configure generators to use the gems we want, and skip view spec generation

# in config/application.rb

config.generators do |g|
  g.test_framework :rspec, :fixture => true
  g.fixture_replacement :factory_girl, :dir => 'spec/factories'
  g.form_builder :simple_form
  g.template_engine :haml
end

turn on autoloading of lib directory and all its subdirectories

In Rails 3+, the lib directory is no longer autoloaded.

# in config/application.rb
config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]

run install tasks for our gems

rails g rspec:install
rails g simple_form:install

Setup spork.

spork --bootstrap

Setup the correct spec_helper.rb

This is the full spec_helper.rb

require 'rubygems'
require 'spork'
require 'database_cleaner'

#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|
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.start

    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

    # Run specs in random order to surface order dependencies. If you find an
    # order dependency and want to debug it, you can fix the order by providing
    # the seed, which is printed after each run.
    #     --seed 1234
    config.order = "random"

    config.include FactoryGirl::Syntax::Methods

    config.treat_symbols_as_metadata_keys_with_true_values = true
    config.filter_run :focus => true
    config.run_all_when_everything_filtered = true
  end
end

Spork.each_run do
  # This code will be run each time you run your specs.
  DatabaseCleaner.clean
  FactoryGirl.reload
end

RSpec Instafail

echo '--colour
--drb
--require rspec/instafail
--format RSpec::Instafail' > .rspec

The --drb is needed for spork and --colour is for color, because it's pretty.

Pry

In your config/environments/development.rb, near the end before the YourAppName::Application.configure block, put this:

silence_warnings do
  begin
    require 'pry'
    IRB = Pry
  rescue LoadError
  end
end

Now rails c will startup using pry. You can also add bindings.pry anyplace and your app will stop there with a pry prompt until you exit it.

Guard

Run these commands:

guard init
guard init bundler
guard init spork
guard init migrate
guard init rspec

Order matters in your Guardfile
