"""Tests for the ``rp2`` target-platform component.
|
|
|
|
``rp2`` is the canonical name for the Raspberry Pi RP-series target
|
|
platform. ``rp2040`` is a deprecated alias declared via
|
|
``ALIASES = ["rp2040"]`` on the rp2 component — the framework
|
|
(see ``esphome/loader.py`` and ``esphome/config.py``) handles both
|
|
Python-import aliasing (via a ``sys.meta_path`` finder) and YAML-key
|
|
aliasing (via a pre-pass in ``validate_config``), so there is no
|
|
hand-rolled shim in ``esphome/components/rp2040/``.
|
|
|
|
These tests pin down the canonical board helpers; the alias contract
|
|
itself (Python imports, YAML key rename, deprecation warning) is covered
|
|
by the framework tests under ``tests/unit_tests/``.
