Puppet user type fails using rspec-puppet-augeas

[gtjwilkicki]

I have written an rspec for an augeas resource I want to test and I'm getting an error when I try to run the test:

Failure/Error: should execute.with_change

My spec_helper looks like this:

require 'rubygems'
require 'puppetlabs_spec_helper/module_spec_helper'
require 'rspec-puppet-augeas'

# Create temporary config file
require 'erb'
require 'fileutils'
require 'tempfile'
require 'tmpdir'

tempdir = Dir.mktmpdir("my-spec")
parentdir = File.dirname(File.expand_path(__FILE__))
config_template = File.join(parentdir,'fixtures','puppet','puppet.conf.erb')

renderer = ERB.new(File.read(config_template))

user = Etc.getpwuid(Process.uid).name

temp_conf_name = File.join(tempdir,"puppet.conf")
temp_conf = File.open(temp_conf_name,"w+")

begin
  temp_conf.puts(renderer.result(binding))
ensure
  temp_conf.close
end

RSpec.configure do |c|
   c.config = temp_conf_name
   c.module_path = File.join(parentdir, 'fixtures', 'modules')
   c.manifest_dir = File.join(parentdir, 'fixtures', 'manifests')
  c.augeas_fixtures = File.join(parentdir,'fixtures','augeas')

  c.after(:all) do
    FileUtils.remove_entry_secure(tempdir,true)
  end
end

The code with the temp file is my attempt to provide a custom puppet.conf that forces the user to be the process owner, since issue 15 seemed to indicate that Puppet might not like running as a non-root user. I've also tried without a custom puppet.conf, per the example in the README file.

My spec is pretty basic:

require 'spec_helper'

describe 'my::class' do

   describe 'has augeas resource' do
          it {
              should contain_augeas('my attrs')
         }
  end
end

Puppet version is 3.8.3 and I'm using rspec 3.4.0 with rspec-puppet-augeas 0.4.0 on Ruby 2.1.5.
