J. Nick Koston 22fa536fa5 Simplify the native toolchain driver
Drops the ninja dry-run probe (a second full manifest load and stat
sweep per build to suppress one line), the compile-database stamp file
(a plain mtime compare says the same), and the ccache sentinel
(resolve_ccache_path only spawns when it returns a value, so a plain
fallback never re-probes). The crash decoder resolves addr2line and
the ELF once per run instead of once per address, which removes the
module-level warn-dedup dict along with its test fixture. The size
summary uses the toolchain path it was handed rather than re-deriving
it, and its two failure branches merge.

The framework import moves into the functions that need it: the serial
upload and logs fast path resolves this module for artifact paths
alone and was paying 16 ms and 29 modules for the package-download
stack. test_lazy_imports now guards that module so it cannot come
back. analyze-memory's idedata candidate list learns the suffixed
native cache name, and warn_if_idedata_missing goes back to being a
one-for-one extraction.

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.

Test name Platform Network BLE
test1.yaml ESP32 wifi None
test2.yaml ESP32 ethernet esp32_ble_tracker
test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None
test5.yaml ESP32 wifi ble_server
test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
