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' containing two clean files
    When I run reek --format yaml clean
    Then it succeeds
    And it reports this yaml:
    """
    --- []
    """

  Scenario: Indicate smells and print them as yaml when using files
    Given the smelly file 'smelly.rb'
    When I run reek --format yaml smelly.rb
    Then the exit status indicates smells
    And it reports this yaml:
      """
      ---
      - context: Smelly#x
        lines:
        - 4
        message: has the name 'x'
        smell_type: UncommunicativeMethodName
        source: smelly.rb
        name: x
        wiki_link: https://github.com/troessner/reek/blob/master/docs/Uncommunicative-Method-Name.md
      - context: Smelly#x
        lines:
        - 5
        message: has the variable name 'y'
        smell_type: UncommunicativeVariableName
        source: smelly.rb
        name: y
        wiki_link: https://github.com/troessner/reek/blob/master/docs/Uncommunicative-Variable-Name.md
      """

  Scenario: Indicate smells and print them as yaml when using STDIN
    When I pass "class Turn; end" to reek --format yaml
    Then the exit status indicates smells
    And it reports this yaml:
      """
      ---
      - smell_type: IrresponsibleModule
        source: "STDIN"
        context: Turn
        lines:
