plesty.lib.test.grouped_param_keys
==================================

.. py:module:: plesty.lib.test.grouped_param_keys

.. autoapi-nested-parse::

   Tests for grouped parameter key resolution in ConfigSystem.

   The three ``test_*`` functions are collected by pytest when imported into a
   suite, but the module itself imports nothing from pytest: it ships in
   ``plesty-lib``, where pytest is a dev-group dependency (#19).



Functions

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

.. py:function:: _assert_key_error(call: collections.abc.Callable[[], Any], key: str) -> None

   Assert that looking up ``key`` raises KeyError.


.. py:function:: _build_config_system() -> plesty.lib.device.params.ConfigSystem

.. py:function:: test_default_param_uses_bare_key_only() -> None

   Verify default-group params are accessible only by bare key, not prefixed key.


.. py:function:: test_grouped_param_requires_full_key() -> None

   Verify grouped params require the full prefix.key form.


.. py:function:: test_get_config_list_returns_full_keys_for_grouped_params() -> None

   Verify get_config_list returns full keys for grouped params and bare keys for defaults.
