使用chef generate cookbook hello 命令时，生成的serverspec spec_helper.rb 文件将不适用于Test-Kitchen 1.4.1 和windows。

kitchen verify 命令在 windows 平台上会抛出以下内容：

C:/Users/vagrant/AppData/Local/Temp/verifier/gems/gems/specinfra-2.37.5/lib/specinfra/backend/exec.rb:98:in `spawn': No such file or directory - /bin/sh -c ls\ /etc/arch-release (Errno::ENOENT)

【解决方案1】：

更改 test-kitchen spec_helper.rb 文件以测试 windows 并相应地设置后端和操作系统，解决问题：

require 'serverspec'

if (/cygwin|mswin|mingw|bccwin|wince|emx/ =~ RUBY_PLATFORM).nil?
  set :backend, :exec
else
  set :backend, :cmd
  set :os, family: 'windows'
end

然后您可以针对不同的平台进行测试，例如：

require 'spec_helper'

case os[:family]
when 'windows'
  describe file('C:\Users\vagrant\foo.txt') do
    it { should be_file }
  end
when 'darwin' # mac os x
  describe file('/user/vagrant/foo.txt') do
    it { should be_file }
  end
when 'ubuntu'
  describe file('/home/vagrant/foo.txt') do
    it { should be_file }
  end
end
