Gem Rails 3.2.13 使用 Spork + Guard + RSpec + Capybara
读这篇比我的好
比较匆忙的同学请看
rails new appname --skip-test-unit --skip-bundle- 复制 Gemfile，替换掉项目下的 Gemfile:
-
安装需要的 Gems，你有两个选择：
-
bundle install，之后使用bundle exec xxx
-
bundle install --binstubs，之后使用bin/xxx
-
rails generate rspec:install- 运行
bin/guard init rspec && bin/guard init spork
- 复制这个 Guardfile，覆盖掉项目下的 Guardfile。
- 添加
--drb至项目的根目录下的.rspec。 复制这个 spec/spec_helper.rb，覆盖
spec/spec_helper.rbbundle exec spork --bootstrap或bin/sprok --bootstrapbundle exec guard或bin/guard
-- FINISH --
有 10 分钟的同学请看
为什么使用 Guard？
- 要切回终端机敲 RSpec 命令
- 启动速度太慢 (使用 Spork 来加速)
Guard 人如其名，自动侦测改动并运行测试。
配置
添加 guard-rspec gem：
Gemfile:
group :development, :test do
gem 'guard-rspec', '1.2.1'
end
在 :test group 加入一些相依的 Gems，OSX 可能需要安装 growl-notify：
Growlnotify 效果圖：
MacOSX
gem 'rb-fsevent', '0.9.1', :require => false
gem 'growl', '1.0.3'
Linux
gem 'rb-inotify', '0.8.8'
gem 'libnotify', '0.5.9'
Windows
gem 'rb-fchange', '0.0.5'
gem 'rb-notifu', '0.0.4'
gem 'win32console', '1.3.0'
范例 Gemfile，放在 Gist:
Gemfile 配置好运行 bundle install ，初始化 Guard：
bundle exec guard init rspec
或是运行 bundle install --binstubs，初始化 Guard：
bin/guard init rspec
会产生一个 Guardfile，最上方加入此行：
require 'active_support/core_ext'
并改动此行 guard 'rspec', :version => 2 do ：
guard 'rspec', :version => 2, :all_after_pass => false do
确保 Guard 一个失败测试通过以后，不会运行所有的测试（加快 红绿重构 周期）
再添加：
guard 'rspec', :version => 2, :all_after_pass => false do
.
.
.
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
.
.
.
end
当 integration tests 及 views 有变动时，会自动运行测试。
这些都设置好了，启动 guard
bundle exec guard
或
bin/guard
更多信息请参考：Guard Github 页面
使用 Spork 来加速测试
运行 RSpec 很慢的原因是每次都得重加载整个 Rails 环境。Spork 测试服务器透过加载 Rails 环境，并维护一个进程池 (pool of processes) 给之后的测试使用。跟 Guard 搭配使用顺风顺水。
配置 Gemfile，将此行加入 :test group：
gem 'guard-spork', '0.3.2'
gem 'spork', '0.9.0'
范例 Gemfile，放在 Gist:
运行 bundle install 并运行 spork：
bundle exec spork --bootstrap
运行 bundle install --binstubs 并运行 spork：
spork --bootstrap # or bin/spork --bootstrap
添加需加载的环境信息至 spec/spec_helper.rb 里的 Spork.prefork：
require 'rubygems'
require 'spork'
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'
# 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
# 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
end
end
Spork.each_run do
# This code will be run each time you run your specs.
end
启动 Spork 服务器：
之前使用 bundle install：
bundle exec spark
之前使用 bundle install --binstubs
bin/spork
加入此行至 .rspec ，让 RSpec 缺省使用 spork：
--drb
提示 ：
如果改动了 routes.rb 需重启 Spork 服务器，如果你觉得测试是对的，但是失败了，也可以重启 Spork 服务器试试看。
更多信息请参考 Spork Github 页面
Guard 搭配 Spork
有了 Guard 与 Spork 以后，让它们合体：
bundle exec guard init spork
bin/guard init spork
加入此段代码至 Guardfile：
guard 'spork', :rspec_env => { 'RAILS_ENV' => 'test' } do
watch('config/application.rb')
watch('config/environment.rb')
watch(%r{^config/environments/.+\.rb$})
watch(%r{^config/initializers/.+\.rb$})
watch('Gemfile')
watch('Gemfile.lock')
watch('spec/spec_helper.rb')
watch('test/test_helper.rb')
watch('spec/support/')
end
guard 'rspec', :version => 2, :all_after_pass => false, :cli => '--drb' do
.
.
.
end
现在全都设定好了，以后只要
bundle exec guard 或 bin/guard
Guard 就会自动启动 Spork 服务器并侦测你的改动！
一个常见的错误
ERROR: Could not start Spork server for Test::Unit & RSpec after 30 seconds.
如果没有使用 Test::Unit，把 test/ 目录移除或更名即可。
：D
不错，不过建议楼主可以用 guard-spork，这样一个 guard 可以全包了
贴一个傻瓜型 Gemfile 带了 guard,livereload 等等一体化自动测试
require 'rbconfig'
HOST_OS = RbConfig::CONFIG['host_os']
source 'http://rubygems.org'
gem 'rails', '3.2.3'
# Gems used only for assets and not required
# in production environments by default.

# Use unicorn as the web server

group :test do
# Pretty printed test output
gem 'turn', :require => false
gem 'factory_girl_rails' , "~> 1.1.0" ,:require => false

gem 'guard-spork'

end
执行guard init 然后按照需要调整 Guardfile，确保 spork 在 rspec 的上面
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
guard 'livereload' do
watch(%r{app/.+\.(erb|haml)})
watch(%r{app/helpers/.+\.rb})
watch(%r{(public/|app/assets).+\.(css|js|html)})
watch(%r{(app/assets/.+\.css)\.s[ac]ss}) { |m| m[1] }
watch(%r{(app/assets/.+\.js)\.coffee}) { |m| m[1] }
watch(%r{config/locales/.+\.yml})
end
guard 'pow' do
watch('.powrc')
watch('.powenv')
watch('.rvmrc')
watch('Gemfile')
watch('Gemfile.lock')
watch('config/application.rb')
watch('config/environment.rb')
watch(%r{^config/environments/.*\.rb$})
watch(%r{^config/initializers/.*\.rb$})
watch(%r{^config/settings(\.local)?\.yml$})
end
guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, :rspec_env => { 'RAILS_ENV' => 'test' } do
watch('config/application.rb')
watch('config/environment.rb')
watch(%r{^config/environments/.+\.rb$})
watch(%r{^config/initializers/.+\.rb$})
watch('spec/spec_helper.rb')
end
guard 'rspec', :version => 2 ,:cli => "--drb",:notification => true do
watch(%r{^spec/.+_spec\.rb$})
watch(%r{^lib/(.+)\.rb$}) { |m| "spec/lib/#{m[1]}_spec.rb" }
watch('spec/spec_helper.rb') { "spec/" }
# Rails example
watch(%r{^spec/.+_spec\.rb$})
watch(%r{^app/(.+)\.rb$}) { |m| "spec/#{m[1]}_spec.rb" }
watch(%r{^lib/(.+)\.rb$}) { |m| "spec/lib/#{m[1]}_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('spec/spec_helper.rb') { "spec/" }
watch('config/routes.rb') { "spec/routing" }
watch('app/controllers/application_controller.rb') { "spec/controllers" }
# Capybara request specs
watch(%r{^app/views/(.+)/.*\.(erb|haml)$}) { |m| "spec/requests/#{m[1]}_spec.rb" }
end
然后参照楼主的文章设置一下 spec_helper.rb
执行guard即可开始自动测试，自动重启服务，自动 bundle 等等
guard 挺好的，只是我每写几行代码就很习惯地保存一下，guard 跑个不停...而且有时会出现一些灵异错误怎么跑都跑不过，最后重启 guard 才过了，可能没配置好。@Juanito 有没有出现过这种问题？
#3 楼 @aNdReW_Qx 有个问题，guard-livereload 怎么连不上浏览器呢？我都已经装了浏览器扩展，但是当我修改一个 view 的时候，浏览器都没有自动刷新。我在 ubuntu 下，guardfile 里面的 pow 段没用，被我删掉了。
看了这篇文章，才真正知道咱社区常说的 Guard 是个啥玩意儿。
之前一直以为是一个 Mac 下专用的，类似于 autotest 的玩意儿，现在才明白，Guard 原来是全方位的...
太谢谢@Juanito啦。
bundle exec guard init spec ，新版本中应改为 bundle exec guard init rspec ，另外，在 windows xp，还需要 gem wdm ,否则出错。
我这边 windows7 用 unit test 在 opensuse 下什么问题都没有 切 windows 下面提示，然后修改文件是没有反应的。也就是说没有监视到文件的变化
Please add the following to your Gemfile to avoid polling for changes:
require 'rbconfig'
if RbConfig::CONFIG['target_os'] =~ /mswin|mingw|cygwin/i
gem 'wdm', '>= 0.1.0'
end
然后我加了 wdm，再然后
11:21:07 - INFO - Guard is now watching at 'F:/src/guard'
Process finished with exit code -1073741819
rubymine 中会有Process finished with exit code -1073741819
而 cmd 终端显示 now watching 之后就直接显示
F:\src\guard>
同样的代码，opensuse 完全木有问题，求问是怎么回事
