Feature: Create thumbs for an image if they don't exist
  `allmytoes` will create missing thumbnails when called with an image file for which no up-to-date
  thumbnail exists.

  `allmytoes` only checks the existance of the thumb with the requested size.
  However, if that thumb does not exist or is outdated, _all_ missing or outdated thumbs
  will be created for the input file.

  Scenario Outline: Request thumbnail for image for which no thumbnail exists
    Given a JPEG image as input
    And no thumbs exist
    When allmytoes is started with arguments <sizearg>
    Then the path to the <size> thumb is returned
    And valid thumb exist for size <size>
    And no thumb exists for sizes other than <size>

    Examples: size-args and sizes
      | sizearg         | size         |
      | -sn             | normal       |
      | -sl             | large        |
      | -sx             | x-large      |
      | -sxx            | xx-large     |


  Scenario: Request thumbnail for 16 bit image
    Given a 16-bit RGB PNG image as input
    And no thumbs exist
    When allmytoes is started without further arguments
    Then the path to the large thumb is returned
    And valid thumb exist for size large
    And no thumb exists for sizes other than large
