Feature: Configurable
  As a Ruby developer
  I want to be able to configure tailor to my style likings
  So that tailor only detects the problems that I care about.

  Scenario: No config file exists
    Given a file named ".tailorrc" should not exist
    When I successfully run `tailor --show-config`
    Then the output should contain:
      """
      +---------------------------+------------------+
      |                Configuration                 |
      +---------------------------+------------------+
      |    Indentation                               |
      +---------------------------+------------------+
      |    spaces                 |    2             |
      |    allow_hard_tabs        |    false         |

    And the exit status should be 0
