Chef警告ChefSpec的平台和版本运行覆盖率

Coverage 使用 spec_helper.rb 文件如下:

require 'chefspec'
require 'chefspec/berkshelf'

ChefSpec::Coverage.start! do
  add_output do |reportOutput|
    File.open( "coverage.json","w" ) do |f| 
      f.puts(reportOutput[:total])
      f.puts(reportOutput[:touched])
      f.puts(reportOutput[:coverage])
      f.puts(reportOutput[:untouched_resources])
      f.puts(reportOutput[:all_resources])
    end 
  end 
end

rspec

WARNING: you must specify a 'platform' and 'version' to your ChefSpec 
Runner and/or Fauxhai constructor, in the future omitting these will 
become a hard error. A list of available platforms is available at 
https://github.com/chefspec/fauxhai/blob/master/PLATFORMS.md
