J. Nick Koston cdb2e32518 [water_heater] Fix device_id missing from state responses
Water heater was the only entity type that directly called
encode_message_to_buffer() instead of fill_and_encode_entity_state().
This meant device_id was never set on WaterHeaterStateResponse,
causing entities with device_id to show as unknown in Home Assistant.

Expand the device_id integration test to cover all entity types:
cover, fan, lock, number, select, text, valve, water_heater,
alarm_control_panel, date, time, datetime, and event.

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
