[SOLVED] Puppet: rake spec could not find class ::splunk

I'm trying to tests my puppet modules, but I get an error message that it can't find class.

I've written a couple of internally used Puppet modules; now that I have my head around puppet, I want to write tests. Since I ran into issues, I decided to essentially start over with a new clean module to figure out what I need to do.

$puppet module generate wet-splunk
<<snip interactive questions>>
$cd splunk
$rake spec
<path snip>ruby -I/Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-support-3.4.1/lib:/Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-core-3.4.1/lib /Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-core-3.4.1/exe/rspec --pattern spec/\{classes,defines,unit,functions,hosts,integration,types\}/\*\*/\*_spec.rb --color

Checking the files though I think they contain what they should:

manifests/init.pp

# <snip documentation boilterplate>
class splunk {    
}

spec/classes/init_spec.rb

require 'spec_helper'
describe 'splunk' do

  context 'with defaults for all parameters' do
    it { should contain_class('splunk') }
  end
end

The Could not find class ::splunk is the part that has me confused.

The way I read the spec file is it looking inside init for class{'splunk': ... } That could be me misreading it as it seems odd they would start with a broken spec file, but just in case I tried testing for package instead.

manifests/init.pp

class splunk {
  package{'splunk':
    ensure => 'present',
  }
}

spec/classes/init_spec.rb

require 'spec_helper'
describe 'splunk' do

  context 'with defaults for all parameters' do
    it { should contain_package('splunk') }
  end
end

I still get a similar error message:

$ rake spec

Sorry to ask such a basic question; I really appreciate your help. I'd really love links to good tutorials on testing Puppet code; I'd love to use Vagrant to have some confidence my code is actually going to do what I want it to.

Update: I believe I have followed @Peter_Souter's suggestions; I still get the error that it can't find the class. I'm posting the contents of the files referenced to try and validate I did the right thing and in case there are other errors.

$ cat .fixtures.yml 
fixtures:
  symlinks:
    "splunk": "#{source_dir}"
$ cat spec_helper.rb 
require 'puppetlabs_spec_helper/module_spec_helper'
$ cat Rakefile 
require 'puppetlabs_spec_helper/rake_tasks'
require 'puppet-lint/tasks/puppet-lint'
PuppetLint.configuration.send('disable_80chars')
PuppetLint.configuration.ignore_paths = ["spec/**/*.pp", "pkg/**/*.pp"]

desc "Validate manifests, templates, and ruby files"
task :validate do
  Dir['manifests/**/*.pp'].each do |manifest|
    sh "puppet parser validate --noop #{manifest}"
  end
  Dir['spec/**/*.rb','lib/**/*.rb'].each do |ruby_file|
    sh "ruby -c #{ruby_file}" unless ruby_file =~ /spec\/fixtures/
  end
