Feature: ascii-data-qdiff support
  In order to see the difference between the contents of ascii-encoded record streams
  As a tester
  I want a tool to decode, normalise, sort, pretty print the streams and show them in a diffing editor
  
  Scenario: comparing identical files
    When ascii-data-qdiff is invoked on files containing:
      """
      EXAMPLE01MO 1112345678      442012345678    0012\n  ||  EXAMPLE01MO 1112345678      442012345678    0012\n
      """
    Then the user receives the following feedback:
      """
      The files are identical.
      
      """

  Scenario: normal execution
    When ascii-data-qdiff is invoked on files containing:
      """
      EXAMPLE01MO 1112345678      442012345678    0012\n  ||  EXAMPLE01MO 9954321098      442012345678    0012\n

    Then the diffed result should be:
