Feature: Return existing thumb if it exists
  Calling `allmytoes` with a single file for which up-to-date
  thumbnails exists in the thumb database, the path to an existing thumb will
  be returned without any side-effects.

  `allmytoes` provides a switch to choose the size of the returned thumbnail.


  Scenario: Get existing large thumb by default
    Given a JPEG image as input
    And   thumbs exists for the input in standard DB
    When  allmytoes is started without further arguments
    Then  the path to the large thumb is returned
    And   the thumbs have not been changed


  Scenario Outline: Get existing thumb with specific size
    Given a JPEG image as input
    And   thumbs exists for the input in standard DB
    When  allmytoes is started with arguments <sizearg>
    Then  the path to the <size> thumb is returned
    And   the thumbs have not been changed
