[Puppet Users] rspec-puppet: let( :title ) isn't setting title

[Chris Galli]

I've created a simple module to play with rspec-puppet, and I'm having 
trouble getting my tests to pass because it appears I can't set the value 
of $title -- It's always the name of my module.

I think perhaps I'm not understanding something about $title in puppet or 
let( :title ) in rspec-puppet.


Here's what I'm testing and the results I'm getting.

Create module:
$ puppet module generate --skip-interview poc-filez 



Module contents (*poc-filez/manifests/init.pp*):
class filez {

  file { $title:
    # have also tried "${title}"
    ensure => "present",
  }
}




Spec contents (*poc-filez/spec/classes/init_spec.rb*)
require 'spec_helper'
describe 'filez' do
  expected_title = '/home/me/foo'
  let(:title) { expected_title }
  # have tried variations, e.g. let (:title) { "#{expected_title" }


  # this fails  
  it { should contain_file("#{expected_title}") }
  
  # but when I use the module name, it passes, File[filez] is in the catalog
  # it { should contain_file("filez") }
end



*.fixtures.yml* contents:
fixtures:

  repositories:
    #
  symlinks:
    filez: "#{source_dir}"




Test results:
$ rake spec


Failures:


  1) filez should contain File[/home/me/foo]
     Failure/Error: it { should contain_file("#{expected_title}") }
       expected that the catalogue would contain File[/home/me/foo]



However, if I change the module to use $name, and pass $name as a parameter 
in the spec, then my tests pass, e.g.

*manifests/init.pp*
class filez {
  file { $name:
    ensure => "present",

  }
}


*spec/classes/init_spec.rb*
require 'spec_helper'
describe 'filez' do
  expected_title = '/home/me/foo'
  let(:params) {{ :name => expected_title }}


  # this passes
  it { should contain_file("#{expected_title}") }

  
  # this fails
  # it { should contain_file("filez") } 
end



I've examined other projects that use rspec-puppet and let( :title ) and on 
the surface they seems very similar.  But obviously, I'm missing something 
or not doing something correctly.  Any insight would be greatly 
appreciated.  I've got several legacy modules that use $title, so I'm 
hesitant to simply accept changing them to use name (unless of course 
that's the root of my problem).

Much appreciated,

Chris
