ruby-on-rails – Rails,Minitest和Guard – 为什么rb-fsevent占

如果我很幸运,它会运行所有测试一次,也许两次.在那之后,即使一个小的测试文件被更改,使用gem变得徒劳也需要很长时间才能响应.

当测试运行时跟随顶部时,我可以看到有一个ruby进程不断占用CPU的100％以上.即使所有测试都运行完毕,我也没有对文件进行任何更改.

ruby过程是：

/Users/Bodacious/.rvm/gems/ruby-2.0.0-p247@MyApp/gems/rb-fsevent-0.9.3/bin/fsevent_watch --latency 0.1 /Users/Bodaiou/Clients/MyApp

Ruby 2.0.0-p247

这是我的设置：

# Gemfile (with irrelevant gems removed)
gem 'rails','4.0.0'
group :test do
  gem 'launchy'
  gem "mocha",require: false
  gem 'database_cleaner'
  gem 'selenium-webdriver'
  gem 'capybara-webkit' # for headless javascript tests
  gem 'timecop'
  gem "minitest-focus"
end

group :development,:test do
  gem "minitest-rails"
  gem "minitest-rails-capybara"
  gem 'zeus'
  gem 'guard'
  gem 'guard-minitest'
  gem 'factory_girl_rails'
end


# Guardfile
guard :minitest,all_on_start: false do
  # Rails 4
  watch(%r{^app/(.+).rb})                               { |m| "test/#{m[1]}_test.rb" }
  watch(%r{^app/controllers/application_controller.rb}) { 'test/controllers' }
  watch(%r{^app/controllers/(.+)_controller.rb})        { |m| "test/integration/#{m[1]}_test.rb" }
  watch(%r{^app/views/(.+)_mailer/.+})                   { |m| "test/mailers/#{m[1]}_mailer_test.rb" }
  watch(%r{^lib/(.+).rb})                               { |m| "test/lib/#{m[1]}_test.rb" }
  watch(%r{^test/.+_test.rb})
  watch(%r{^test/test_helper.rb})                       { 'test' }

  ignore(%r{^tmp/})

end

# test_helper
ENV["RAILS_ENV"] = "test"
require File.expand_path("../../config/environment",__FILE__)

require 'rails/test_help'
require 'minitest/autorun'
require 'minitest/pride'

Dir[Rails.root.join('test','support','*.rb')].each do |file|
  require file
