id3c.tests.test_external_link_target
====================================

.. py:module:: id3c.tests.test_external_link_target

.. autoapi-nested-parse::

   Tests for ``id3c.plans.flyscan_3idc._external_link_target``.

   Pure-Python: builds duck-typed det.hdf1 objects from synthetic
   templates and IOC paths, exercises the common-suffix construction,
   the legacy fallback, and the warning paths.

Module Contents
---------------

.. py:function:: test_strips_write_path_template_prefix()

   write_path_template prefix is stripped from full_file_name.

   The remaining common suffix is appended to the per-detector root.


.. py:function:: test_handles_template_without_trailing_slash()

   write_path_template without a trailing slash is normalized.


.. py:function:: test_custom_ad_files_root()

   A non-default ad_files_root parameter is honoured.


.. py:function:: test_falls_back_when_template_missing(caplog)

   Missing write_path_template falls back to legacy target.

   Encapsulates the full absolute path and logs a WARNING.


.. py:function:: test_falls_back_when_template_does_not_prefix_full_file_name(caplog)

   Stale write_path_template (no prefix match) falls back.

   Logs a WARNING and uses the legacy absolute-path target.


.. py:function:: test_template_equal_to_full_file_name_yields_empty_suffix()

   Empty suffix when full_file_name equals the template.

   The helper handles this rather than raising.


.. py:function:: test_uses_underscore_write_path_template_fallback()

   Falls back to _write_path_template if write_path_template is absent.
