Location tracking tests for JSON Feed parser
===========================================

This test suite verifies that jsont combinators correctly track location
information for both valid and invalid JSON feeds.

Valid Feeds
-----------

Test minimal valid feed:
  $ ./test_location_errors.exe data/minimal_valid.json title
  {"status":"ok","field":"title","value":"Minimal Feed"}

  $ ./test_location_errors.exe data/minimal_valid.json version
  {"status":"ok","field":"version","value":"https://jsonfeed.org/version/1.1"}

  $ ./test_location_errors.exe data/minimal_valid.json item_count
  {"status":"ok","field":"item_count","value":"0"}

Test complete feed with all fields:
  $ ./test_location_errors.exe data/complete_valid.json title
  {"status":"ok","field":"title","value":"Complete Feed"}

  $ ./test_location_errors.exe data/complete_valid.json item_count
  {"status":"ok","field":"item_count","value":"1"}

  $ ./test_location_errors.exe data/complete_valid.json first_item_id
  {"status":"ok","field":"first_item_id","value":"https://example.com/item1"}

Test mixed content types:
  $ ./test_location_errors.exe data/mixed_content.json item_count
  {"status":"ok","field":"item_count","value":"3"}

Test feed with extensions:
  $ ./test_location_errors.exe data/with_extensions.json title
  {"status":"ok","field":"title","value":"Feed with Extensions"}
