Test-Kitchen serverspec testing exception on windows - windows

Question

When using chef generate cookbook hello command, the serverspec spec_helper.rb file generated will not work with Test-Kitchen 1.4.1 and windows.
kitchen verify command will throw the following on windows platform:
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)

Changing the test-kitchen spec_helper.rb file to test for windows and setting the backend and os accordingly, fixes the issue:
require 'serverspec'
if (/cygwin|mswin|mingw|bccwin|wince|emx/ =~ RUBY_PLATFORM).nil?
set :backend, :exec
else
set :backend, :cmd
set :os, family: 'windows'
end
You can then test against different platforms, for example:
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
