Rspec-Puppet tests fails with undefined variable for all custom facts used, when using STRICT_VARIABLES

[cardil]

Tests in rspec-puppet fails with message similar to:

Undefined variable "::augeasversion"; Undefined variable "augeasversion" at /code/puppet/jboss/spec/fixtures/modules/jboss/manifests/internal/augeas.pp:4

Those issues can be fixed by setting those facts in test like this:

on_supported_os do |os, facts|
  let(:facts) { facts.merge(:jboss_running => false) }
end
