J. Nick Koston 17f718e8c9 Simplify the native dispatch and CI cache wiring
A cache-arduino8266 composite action mirrors cache-esp-idf (one key
resolver, dev-writes/PR-restores) and both jobs pin
ESPHOME_ARDUINO8266_PREFIX so YAML and Python agree on the path by
construction. esp32 provides the native_toolchain_module hook, so the
shared dispatcher never names a backend and the unclaimed-native raise
loses its esp-idf carve-out; the esp8266 decode and run_compile hooks
resolve through the same seam. run_compile resolves ccache once and
threads it to the generator, env, and idedata; the compdb rule names
follow the shared kinds; the pio-options warner inlines into the driver
and derives its consumed set from the core routing constant; the
per-toolchain CI narrowing shares one body; create_components_graph is
memoized per run; the decode rate-limit drops its math sentinel.

Tests for ESPHome

This directory contains some tests for ESPHome. At the moment, all the tests only work by simply executing esphome over some YAML files that are made to test whether the yaml gets converted to the proper C++ code.

Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.

When adding entries in test_.yaml files we usually need only one file updated, unless conflicting code is generated for different configurations, e.g. wifi and ethernet cannot be tested on the same device.

Current test_.yaml file contents.
