Rails Project Init

 1.rspec

$ rails generate rspec:install

 2.guard

$ bundle exec guard init rspec

 3.加入默认 Guardfile 的代码，注意顶部的 require

require 'active_support/inflector'

guard 'rspec', all_after_pass: false do
  .
  .
  .
  watch('config/routes.rb')
  # Custom Rails Tutorial specs
  watch(%r{^app/controllers/(.+)_(controller)\.rb$}) do |m|
    ["spec/routing/#{m[1]}_routing_spec.rb",
     "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb",
     "spec/acceptance/#{m[1]}_spec.rb",
     (m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
                       "spec/requests/#{m[1].singularize}_pages_spec.rb")]
  end
  watch(%r{^app/views/(.+)/}) do |m|
    (m[1][/_pages/] ? "spec/requests/#{m[1]}_spec.rb" :
                      "spec/requests/#{m[1].singularize}_pages_spec.rb")
  end
  watch(%r{^app/controllers/sessions_controller\.rb$}) do |m|
    "spec/requests/authentication_pages_spec.rb"
  end
  .
  .
  .
end

 4.spork

$ bundle exec spork --bootstrap

 5.将环境加载代码加入 Spork.prefork 代码块:spec/spec_helper.rb 

require 'rubygems'
require 'spork'

Spork.prefork do
  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}

  # Checks for pending migrations before tests are run.
  # If you are not using ActiveRecord, you can remove this line.
  ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

  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

    # 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 Capybara::DSL
  end
end

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

end

 6.Guard 和 Spork 协作

 

$ bundle exec guard init spork

 7.为使用 Spork 而修改的 Guardfile 

require 'active_support/inflector'

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', all_after_pass: false, cli: '--drb' do
  .
  .
  .
end

 8.修改完之后，我们就可以通过 guard 命令同时启动 Guard 和 Spork 了：
