"""Tests for the T9 air-quality (HCHO / VOC) sensor support.
Covers what was added for the WSLink ``t9hcho`` / ``t9voclv`` / ``t9bat`` /
``t9cn`` parameters:
- the new constants (``REMAP_WSLINK_ITEMS``, ``CONNECTION_GATED_SENSORS``,
``BATTERY_NON_BINARY``, ``VOCLevel`` / ``VOC_LEVEL_MAP``)
- the ``utils.voc_level_to_text`` and ``utils.battery_5step_to_pct`` helpers
- the connection gating in ``utils.remap_wslink_items``
- the new ``SENSOR_TYPES_WSLINK`` entity descriptions
- the ``hcho`` / ``voc`` / ``t9_battery`` entries in the translation files
