我正在通過Vagrant框(Ubuntu 32位,Rails 4.0.3,Ruby 2.1.0p0)開發Rails項目。Guard + Spork減慢測試,未收到-drb選項
我剛剛嘗試將Spork添加到我的項目中以加快我的測試(使用RSpec,Capybara),並且看到顯着較慢的測試。如果我只運行「rspec」,我的所有測試通過5.83秒。但是,當我通過「guard -c -p」跑衛隊時,我保存了一個我的規格文件,我得到了26.08秒的時間。
注:我必須運行「guard -p」才能真正得到警惕,通過Vagrant運行我的測試文件保存。
當後衛開始運行測試,它顯示了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」列出兩次,而「--drb」沒有顯示出來的。
這裏是我的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
這裏是我的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的相關部分:
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
我發現,如果我有後衛跑,然後保存文件時,有時我會得到一個錯誤:
Could not start Spork server for rspec after 30 seconds. I will continue
waiting for a further 60 seconds.
我m不知道爲什麼安裝Spork後需要這麼長時間,特別是當rspec通過相同的Vagrant盒時速度更快。有任何想法嗎?
如果我刪除了-p標誌,測試速度可達約5秒(只有12測試,以便遠,但它通過Vagrant運行,所以也許我會看到速度隨着時間的推移而增加)。但是,我必須在運行Guard的控制檯窗口中手動按下'enter',它將運行所有測試,而不是從文件更改中運行。 –
我在這裏找到了一個討論: https://github.com/guard/guard-rspec/issues/183 基本上,問題似乎與VirtualBox不能讓Guard通過查看文件已經改變,除非您添加-p輪詢參數。相反,它試圖在Spork已經運行時運行一切,這會導致「無法啓動spork」錯誤。這也導致了較慢的測試。 現在,我會堅持只在命令行中輸入'enter'來運行所有測試。我不相信通過讓Guard工作正常,可以節省我在Ruby知識水平上編輯所有寶石的時間。 –
