Question

我需要帮助弄清楚为什么我的rspec测试运行缓慢。

我正在运行spork，guard和rspec。但是，似乎spork每次都重新初始化rails。我很难搞清楚如何调试此问题。我怀疑我使用的一些宝石是造成这种但没有证据的。

我认为它正在重新加载的原因是：

在spork内部或外部运行需要相同的时间
我得到了这个警告（与SOLR宝石有关），这是我跑步时得到的 rails服务器

运行所有规格

DEPRECATION警告：不再自动包含ActiveSupport :: Concern中的InstanceMethods模块。请直接在Sunspot :: Rails :: SolrInstrumentation中定义实例方法。（来自/home/dougt/replyinline/config/environment.rb:5）

这是我的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'

  # 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|
    # == 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
    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
    config.include Devise::TestHelpers, :type => :view

    #https://github.com/plataformatec/devise/wiki/How-To:-Controllers-and-Views-tests-with-Rails-3-(and-rspec)
    config.extend ControllerMacros, :type => :controller
    config.extend ControllerMacros, :type => :helper
    config.extend ControllerMacros, :type => :view

  end
end

Spork.each_run do
  # This code will be run each time you run your specs.
  #https://github.com/sporkrb/spork/issues/37
#   silence_warnings do
#      Dir["#{Rails.root}/app/models/**/*.rb"].each {|f| load f}
#  end
#  load "#{Rails.root}/config/routes.rb"
#  Dir["#{Rails.root}/app/**/*.rb"].each {|f| load f}

end

您可以对spork进行分析并使用结果来要求prefork块中的内容

http://www.opinionatedprogrammer.com/2011/02/profiling-spork-for-faster-start-up-time/

Devise和其他可能调用reload的宝石也存在问题，可以通过在spec_helper prefork块中添加以下内容来捕获这些方法：

  ...
  ENV["RAILS_ENV"] ||= 'test'      
  # For Devise
  require "rails/application"
  Spork.trap_method(Rails::Application, :reload_routes!)
  Spork.trap_method(Rails::Application::RoutesReloader, :reload!)
  ...

Spork每次初始化导轨并缓慢运行
