Feature: Report smells using simple YAML layout
  In order to parse Reek's output simply and consistently, simply
  output a list of smells in Yaml.

  Scenario: output is empty when there are no smells
    Given a directory called 'clean_files' containing some clean files
    When I run reek --format yaml clean_files
    Then it succeeds
    And it reports this yaml:
    """
    --- []
    """

  Scenario: Indicate smells and print them as yaml when using files
    Given a smelly file called 'smelly.rb'
    When I run reek --format yaml smelly.rb
    Then the exit status indicates smells
    And it reports this yaml:
      """
