Is there a good way to detect if cookbook is being run using chef-zero?

This would be useful for switching test credentials, etc. A piece of documentation about it in README.md would be nice.

How does test-kitchen not already cover this use case?

Technically you can probably look for Chef::Config.local_mode, if you are doing chef-client -z. But I would not suggest this: we've seen if Chef::Config.solo exceptions strewn about through cookbooks, and what it really means is that when you test your cookbook, you aren't testing the cookbook that will run in production. I would use node attributes for your cookbooks to tell it credentials and such.

Thanks for the answer. I want to use these exceptions only for not having to use encrypted data bags when running test-kitchen - didn't find an easy way to distribute required .pem files into VMs during test run.
