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

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

  Scenario: Indicate smells and print them as JSON when using files
    Given a smelly file called 'smelly.rb'
    When I run reek --format json smelly.rb
    Then the exit status indicates smells
    And it reports this JSON:
      """
      [
          {
              "smell_category": "Duplication",
              "smell_type": "DuplicateMethodCall",
              "source": "smelly.rb",
              "context": "Smelly#m",

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