id3c.tests.test_wait_for_openable
=================================

.. py:module:: id3c.tests.test_wait_for_openable

.. autoapi-nested-parse::

   Tests for ``id3c.plans.flyscan_3idc._wait_for_openable``.

   Pure-Python: builds real HDF5 files in a tmp dir, no IOC, no
   ophyd, no bluesky.  Exercises the success path, the
   missing-file path, and the bounded-timeout behaviour.

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

.. py:function:: test_wait_for_openable_returns_true_for_existing_file(tmp_path)

   A valid HDF5 file opens on the first try.


.. py:function:: test_wait_for_openable_returns_false_for_missing_file(tmp_path)

   A nonexistent path returns False after retries (no raise).


.. py:function:: test_wait_for_openable_returns_false_for_non_hdf5_path(tmp_path)

   A path that exists but is not a valid HDF5 file returns False.


.. py:function:: test_wait_for_openable_append_mode_works(tmp_path)

   Append mode opens a writable file successfully.


.. py:function:: test_wait_for_openable_respects_timeout_budget(tmp_path)

   Helper exits within the timeout budget on persistent failure.
