As a reminder, [Dependabot Preview will be shut down on August 3rd, 2021][announcement]. You can merge this pull request to migrate to GitHub-native Dependabot. You can [read the docs][docs] to learn more about what's changing, as well as find out how to get support if you need help migrating. [announcement]: https://github.blog/2021-04-29-goodbye-dependabot-preview-hello-dependabot/ [docs]: https://docs.github.com/en/code-security/supply-chain-security/keeping-your-dependencies-updated-automatically/upgrading-from-dependabotcom-to-github-native-dependabot

Also, something that may be interesting in the doc for totally ignorant people (like me :-) ) is how I can run the tests for a specific version of puppet/ruby. As you can see, I have failures only for one version of that couple, but I am struggling in reproducing: https://github.com/puppetlabs/puppetlabs-stdlib/runs/3859406073?check_suite_focus=true I think ultimately what would be nice is a couple of commands, starting with `docker run`, which would put people in the correct environment they need to run `pdk bundle exec rake spec`. I tried reproducing what's in the workflow file (https://github.com/puppetlabs/puppetlabs-stdlib/blob/15e13b2b63f0f4b24e68a46cd4c2703682006d8f/.github/workflows/spec.yml#L77-L130) If I try to set the env variable `PUPPET_GEM_VERSION`, `pdk` complains ```bash root@943f4a62533a:/tmp/puppetlabs-stdlib# PUPPET_GEM_VERSION=6.0 pdk bundle exec rake spec SPEC=spec/functions/loadjson_spec.rb pdk (INFO): Using Ruby 2.7.3 pdk (INFO): Using Puppet 7.12.0 pdk (WARN): PUPPET_GEM_VERSION is not supported by PDK. Use the --puppet-version option on your PDK command or set the PDK_PUPPET_VERSION environment variable instead ``` If I try with `PDK_PUPPET_VERSION`, I have another issue ``` root@943f4a62533a:/tmp/puppetlabs-stdlib# PDK_PUPPET_VERSION=6.0 pdk bundle exec rake spec SPEC=spec/functions/loadjson_spec.rb pdk (INFO): Using Ruby 2.5.9 pdk (INFO): Using Puppet 6.0.10 pdk (WARN): FACTER_GEM_VERSION is not supported by PDK. Bundler could not find compatible versions for gem "puppet": In Gemfile: puppet (= 6.0.10) puppet-module-posix-system-r2.5 (~> 1.0) was resolved to 1.1.1, which depends on puppet_litmus (~> 0.20) was resolved to 0.30.0, which depends on bolt (>= 2.0.1, = 6.18.0) ```

This looks like a valid reproducer. Now all we need is someone to write a patch to make the tests pass.

Moving the files after your change to new filenames and then restoring the original files unchanged would go a long way.

I still think https://github.com/voxpupuli/puppet-syntax/pull/127#discussion_r517325284 is a comment that hasn't been answered.

@sanfrancrisko at this point I'm uncertain what is expected. I'd like some guidance from the maintainers what the behavior should be. That means either changing the tests (as I suggested) or changing the code to pass the tests. Until I get that feedback I'm blocked.
