J. Nick Koston 2d9d1eabfa [core] Download external_files in parallel
Each component that uses external_files (audio_file, speaker
media_player, ...) currently calls download_content once per file
inline inside a per-item config validator. With ~24 cached audio
files in a Home Assistant Voice PE config, that means ~24 sequential
HEAD round-trips, even when every response is a 304.

This adds download_content_many(items, ...) which fans the per-file
checks out across a ThreadPoolExecutor (capped at 16 workers so
configs with hundreds of files don't open hundreds of sockets), then
refactors audio_file and speaker.media_player to collect URLs at the
list level and call the batch helper once instead of downloading
inside each per-item validator.

Wall time for the validation phase drops from sum(latency) to roughly
max(latency) when the cache is warm.

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

test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None

test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
