I am trying to write some rspec tests for my modules. Most of them now use hiera.

I have a .fixures.yml:

fixtures:
  repositories:
    stdlib: https://github.com/puppetlabs/puppetlabs-stdlib.git
    hiera-puppet: https://github.com/puppetlabs/hiera-puppet.git
  symlinks:
    mongodb: "#{source_dir}"    

and a spec/classes/mongodb_spec.rb:

require 'spec_helper'

describe 'mongodb', :type => 'class' do

  context "On an Ubuntu install, admin and single user" do
    let :facts do
      {
        :osfamily => 'Debian',
        :operatingsystem => 'Ubuntu',
        :operatingsystemrelease => '12.04'
      }
    end

    it {
      should contain_user('XXXX').with( { 'uid' => '***' } )
      should contain_group('XXXX').with( { 'gid' => '***' } )
      should contain_package('mongodb').with( { 'name' => 'mongodb' } )
      should contain_service('mongodb').with( { 'name' => 'mongodb' } )
    }
  end
end

but when I run the spec test, I get:

# rake spec
/usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color
F

Failures:

  1) mongodb On an Ubuntu install, admin and single user
     Failure/Error: should contain_user('XXXX').with( { 'uid' => '***' } )

Module spec testing is relatively new, as is hiera. So far I have been unable to find any suitable solutions. (the back and forth on puppet-dev was interesting, but not helpful).

What changes do I need to make to get this to work? Installing puppet from a gem and hacking on rubylib isn't a viable solution due to corporate policy.

I am using Ubuntu 12.04 LTS + Puppet 2.7.17 + hiera 0.3.0.
