即使我只想使用组为 rspec 启动它，为什么 guard 会同时为 rspec 和 cucumber 启动 spork？答案

【问题标题】：Why does guard start spork both for rspec and cucumber even if I wanted to start it only for rspec using groups?即使我只想使用组为 rspec 启动它，为什么 guard 会同时为 rspec 和 cucumber 启动 spork？

【问题描述】：

在我的 Gemfile 中...

group :development, :test do
  gem 'capybara', "1.1.2"
  gem 'database_cleaner', "0.7.0"

  gem 'cucumber', "1.1.2"
  gem 'cucumber-rails', "1.2.0"

  gem 'rspec-rails', "2.7.0"

  gem 'spork', "0.9.0.rc9"

  gem 'launchy' #launches the page

  gem 'guard-spork', "0.3.1"
  gem 'guard-rspec', "0.5.4"
  gem 'guard-cucumber', "0.7.4"

  gem 'factory_girl_rails'
end

我的 Guardfile 有两个组（:specs 和 :features）。

group :specs do

  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('spec/spec_helper.rb')
  end

  guard :rspec, :version => 2 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

end

group :features do

  guard 'spork', :cucumber_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 'cucumber' do
    watch(%r{^features/.+\.feature$})
    watch(%r{^features/support/.+$})          { 'features' }
    watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
  end

end

当我尝试运行 :specs 组时，我希望警卫只为 Rspec 运行 Spork。

guard -g specs start

但是，我可以从输出中看到，guard 为 Rspec 和 Cucumber 运行了 Spork。

~/current[master]% guard -g specs start
WARNING: You are using Guard outside of Bundler, this is dangerous and may not work. Using `bundle exec guard` is safer.
Guard could not detect any of the supported notification libraries.

是否有任何我可能遗漏的 SPORK 或警卫配置文件？

更新：

去掉保护黄瓜
删除或重命名功能文件夹

【问题讨论】：

标签： rspec cucumber spork guard

【解决方案1】：

您必须在 RSpec 组的 Spork 中禁用 Cucumber，反之亦然：

specs :specs    
  guard :spork, :cucumber => false do
    # ...
  end
end

specs :features    
  guard 'spork', :rspec => false do
    # ...
  end
end

【解决方案2】：

我知道它很旧，但我现在也偶然发现了这个问题并想通了：

我的项目中有一个features 子目录，其中包含一个文件： features/step_definitions/email_steps.rb

查看提交后，我意识到这是从 rails_apps_composer: testing framework 添加的。

所以：

删除子目录features 可防止spork 尝试使用黄瓜。
