The frontend dev would launch Guard like this: [bundle exec] guard -g frontend

While the backend dev would launch it like this: [bundle exec] guard -g backend

Example of excluding files started with dot:

guard 'livereload' do
  watch(%r{app/.*/[^.][^/]+\.(erb|haml|slim)})
  watch(%r{app/helpers/.*/[^.][^/]+\.rb})
  watch(%r{public/(.*/[^.][^/]+\.(css|js|html))}) {|m| m[1] }
  watch(%r{app/assets/(.*/[^.][^/]+\.css)(\.s[ac]ss)?}) { |m| "/assets/#{m[1]}" }
  watch(%r{app/assets/(.*/[^.][^/]+\.js)(\.coffee)?}) { |m| "/assets/#{m[1]}" }
  watch(%r{config/locales/[^.].+\.yml})
end

Using 2 guard-rspec: 1 for spork, 1 for unit tests

I have adopted Avdi Grimm's naming convention for integration specs: *_integration_spec.rb

I use Spork for specs which load the full rails stack such as controllers, integration models specs, ... For models unit tests and libs, I don't want the overhead of Spork.

The challenge was to come up with a simple regex using "Negative lookbehind assertion" in order to avoid running specs twice each time a file is saved.

group 'tests-with-spork' do

  guard 'rspec', :version => 2, :cli => "--drb", :all_after_pass => false do
    watch('spec/spec_helper.rb') { "spec" }

    watch(%r{^spec/controllers/.+_spec\.rb$})
    watch(%r{^spec/models/.+integration_spec\.rb$})
    watch(%r{^spec/helpers/.+_spec\.rb$})
    watch(%r{^spec/routing/.+_spec\.rb$})
    watch(%r{^spec/requests/.+_spec\.rb$})

    watch(%r{^app/models/(.+)\.rb$}) { |m| "spec/models/#{m[1]}_integration_spec.rb" }
    watch(%r{^app/helpers/(.+)\.rb$}) { |m| "spec/helpers/#{m[1]}_spec.rb" }
    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"
      ]
    end

    watch(%r{^spec/support/(.+)\.rb$}) { "spec" }
    watch('config/routes.rb') { "spec/routing" }
    watch('app/controllers/application_controller.rb') { "spec/controllers" }

    watch(%r{^spec/lib/.+_integration_spec\.rb$})
  end
end

group 'unit-tests' do
  guard 'rspec', :version => 2, :all_on_start => false, :all_after_pass => false, :bundler => false do
    watch(%r{^lib/(.+)\.rb$}) { |m| "spec/lib/#{m[1]}_spec.rb" }

    # ?<! Negative lookbehind assertion: ensures that the preceding characters do not match 'integration',
    # but doesn't include those characters in the matched text
    watch(%r{^spec/models/.*(?<!integration)_spec\.rb$})
    watch(%r{^spec/lib/.*(?<!integration)_spec\.rb$})
  end
end
