Overview

Inspec::Runner coordinates the running of tests and is the main entry point to the application.

Users are expected to insantiate a runner, add targets to be run, and then call the run method:

“‘ r = Inspec::Runner.new() r.add_target(“/path/to/some/profile”) r.add_target(“url/to/some/profile”) r.run “`

  # About reading inputs:
  #   @conf gets passed around a lot, eventually to
  # Inspec::InputRegistry.register_external_inputs.
  #
  #   @conf may contain the key :attributes or :inputs, which is to be a Hash
  # of values passed in from the Runner API.
  # This is how kitchen-inspec and the audit_cookbook pass in inputs.
  #
  #   @conf may contain the key :attrs or :input_file, which is to be an Array
  # of file paths, each a YAML file. This how --input-file works.

Instance Method Details

#add_target(target, _opts = []) ⇒ Object

add_target allows the user to add a target whose tests will be run when the user calls the run method.

A target is a path or URL that points to a profile. Using this target we generate a Profile and a ProfileContext. The content (libraries, tests, and inputs) from the Profile are loaded into the ProfileContext.

If the profile depends on other profiles, those profiles will be loaded on-demand when include_content or required_content are called using similar code in Inspec::DSL.

Once the we’ve loaded all of the tests files in the profile, we query the profile for the full list of rules. Those rules are registered with the @test_collector which is ultimately responsible for actually running the tests.

TODO: Deduplicate/clarify the loading code that exists in here, the ProfileContext, the Profile, and Inspec::DSL

end

#all_rules ⇒ Object

In some places we read the rules off of the runner, in other places we read it off of the profile context. To keep the API’s the same, we provide an #all_rules method here as well.
