# This set of tests is for syntax validation, It runs through all of the
# Puppet, Ruby and ERB code in the repositories and validates it with it's
# relevant validator.
#
# If we want to change the scope of these tests the following variables can be
# modified to change which files are in scope:
#   - puppet_search_path
#   - ruby_search_path
#   - erb_search_path
#   - epp_search_path
#
# All paths are relative the the .onceover temporary directory which is created
# as part of a normal Onceover run
require 'puppet'

# Tell Puppet where to find our code. This is relative to the .onceover directory
Puppet.initialize_settings(['--codedir ./etc/puppetlabs/code'])

# Create a Puppet environment that we can interact with
env = Puppet.lookup(:current_environment)
loaders = Puppet::Pops::Loaders.new(env)
