J. Nick Koston a19e817d28 [core] Shrink apply_to_core to what upload/logs actually read
apply_to_core was over-populating: it restored friendly_name,
loaded_integrations, and loaded_platforms even though every
consumer of those three lives inside a component validator
(esp32_camera, esp32, deep_sleep, zigbee, lvgl, zephyr_mcumgr),
and the whole point of the fast path is to skip validation.

Drop them. CORE.__init__ already leaves all three at safe defaults
(None / empty set) for any incidental reader.

What's left is exactly what upload/logs walk:

  - CORE.name (api.client.run_logs, firmware_bin path, mDNS)
  - CORE.build_path (firmware_bin / partition_table_bin / bootloader_bin)
  - CORE.data[KEY_CORE][KEY_TARGET_PLATFORM] (module dispatch, .is_esp32 etc)
  - CORE.data[KEY_CORE][KEY_TARGET_FRAMEWORK] (.is_arduino, firmware_bin branch)

Method body shrinks from 9 statements to 4; setdefault + two
conditional inserts collapse into one dict literal; the
function-local import moves to module top. Drift surface drops
from 7 paired fields to 4. The wizard-only-sidecar None case is
gated once at the load_compiled_config boundary so apply_to_core
no longer has to defend against it.

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
