Clean up carrierwave's files for rspec. Ruby 2.0, Rails 4.0.2.

spec_helper.rb

Dir["#{Rails.root}/app/uploaders/*.rb"].each { |file| require file }
if defined?(CarrierWave)
  CarrierWave::Uploader::Base.descendants.each do |klass|
    next if klass.anonymous?

    klass.class_eval do
      def cache_dir
        "#{Rails.root}/spec/support/uploads/cache"
      end

      def store_dir
        "#{Rails.root}/spec/support/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
      end
    end
  end
end

config.after(:all) do
  if Rails.env.test?
    FileUtils.rm_rf(Dir["#{Rails.root}/spec/support/uploads"])
  end
end

In my case it worked fine if I wrote in rails_helper.rb instead of spec_helper.rb.

Thank you for the idea!
