Method: Inspec::ResourceDSL#method_missing

Defined in:
lib/inspec/plugin/v1/plugin_types/resource.rb

#method_missing(method_name, *arguments, &block) ⇒ Object

Support for Resource DSL plugins. This is called when an unknown method is encountered within a resource class definition. Even tho this is defined as an instance method, it gets added to Inspec::Plugins::Resource via ‘extend`, so this is actually a class defintion.
