$ chef exec inspec version
1.11.0

Your version of InSpec is out of date! The latest version is 1.18.0.

Setup

Create profile

$ chef exec inspec init profile inspec-resource-error

Create simple resources with the following class inheritance

  • resource_a.rb: ResourceA < ResourceB
  • resource_b.rb: ResourceB < Inspec.resource(1)
  • resource_c.rb: ResourceC < ResourceB

Create controls to test resources

  • example_a.rb
  • example_b.rb
  • example_c.rb

Works

libraries/resource_a.rb

class ResourceA < Inspec.resource(1)
  name 'resource_a'
  ...
end # class

Rename resource_b.rb to _resource_b.rb

libraries/_resource_b.rb

class ResourceB < Inspec.resource(1)
  name 'resource_b'
  ...
end # class

class ResourceA < ResourceB
