我正在通过Vagrant框（Ubuntu 32位，Rails 4.0.3，Ruby 2.1.0p0）开发Rails项目。Guard + Spork减慢测试，未收到-drb选项
我刚刚尝试将Spork添加到我的项目中以加快我的测试（使用RSpec，Capybara），并且看到显着较慢的测试。如果我只运行“rspec”，我的所有测试通过5.83秒。但是，当我通过“guard -c -p”跑卫队时，我保存了一个我的规格文件，我得到了26.08秒的时间。
注：我必须运行“guard -p”才能真正得到警惕，通过Vagrant运行我的测试文件保存。
当后卫开始运行测试，它显示了ARGS：
["--color", "--failure-exit-code", "2", "--format", "progress", "--format",
"Guard::RSpec::Formatter", "--require", "/home/vagrant/.rvm/gems/ruby-2.1.0/
gems/guard-rspec-4.2.7/lib/guard/rspec/formatter.rb", "spec"]...
我看到“--format”列出两次，而“--drb”没有显示出来的。
这里是我的Guardfile：
guard 'spork', :rspec_env => { 'RAILS_ENV' => 'test' }, :test_unit => false do
watch('config/application.rb')
watch('config/environment.rb')
watch('config/environments/test.rb')
watch(%r{^config/initializers/.+\.rb$})
watch('Gemfile.lock')
watch('spec/spec_helper.rb') { :rspec }
end
guard :rspec, :cmd => 'rspec --drb' do
watch(%r{^spec/.+_spec\.rb$})
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$}) { "spec" }
watch('config/routes.rb') { "spec/routing" }
watch('app/controllers/application_controller.rb') { "spec/controllers" }
end
guard 'livereload' do
watch(%r{app/views/.+\.(erb|haml|slim)$})
watch(%r{app/helpers/.+\.rb})
watch(%r{public/.+\.(css|js|html)})
watch(%r{config/locales/.+\.yml})
# Rails Assets Pipeline
watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html|png|jpg))).*}) { |m| "/assets/#{m[3]}" }
end
这里是我的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'
require 'capybara/rspec'
# 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|
config.use_transactional_fixtures = true
config.infer_base_class_for_anonymous_controllers = false
config.order = "random"
#Devise
config.include Devise::TestHelpers, type: :controller
#Capybara
config.include Capybara::DSL
end
end
Spork.each_run do
# This code will be run each time you run your specs.
end
的唯一的事情在我.rspec：
--color
我的Gemfile的相关部分：
group :development, :test do
gem 'rspec-rails', '~> 2.0'
gem 'factory_girl_rails'
gem 'guard-rspec'
gem 'guard-livereload'
gem 'spork-rails'
gem 'guard-spork'
end
group :test do
gem 'shoulda-matchers'
gem 'capybara'
end
我发现，如果我有后卫跑，然后保存文件时，有时我会得到一个错误：
Could not start Spork server for rspec after 30 seconds. I will continue
waiting for a further 60 seconds.
我m不知道为什么安装Spork后需要这么长时间，特别是当rspec通过相同的Vagrant盒时速度更快。有任何想法吗？
如果我删除了-p标志，测试速度可达约5秒（只有12测试，以便远，但它通过Vagrant运行，所以也许我会看到速度随着时间的推移而增加）。但是，我必须在运行Guard的控制台窗口中手动按下'enter'，它将运行所有测试，而不是从文件更改中运行。 –
我在这里找到了一个讨论： https://github.com/guard/guard-rspec/issues/183 基本上，问题似乎与VirtualBox不能让Guard通过查看文件已经改变，除非您添加-p轮询参数。相反，它试图在Spork已经运行时运行一切，这会导致“无法启动spork”错误。这也导致了较慢的测试。 现在，我会坚持只在命令行中输入'enter'来运行所有测试。我不相信通过让Guard工作正常，可以节省我在Ruby知识水平上编辑所有宝石的时间。 –
