J. Nick Koston 1ba8b838da [cli] Address Copilot review on --prebuilt-dir
- get_ltchiptool_path: use 'Scripts/' on Windows, 'bin/' elsewhere when
  falling back to PlatformIO's libretiny penv. CPython venvs put scripts
  under Scripts/ on win32 and bin/ on POSIX; the prior hardcoded 'bin'
  would never have found ltchiptool on Windows.
- _load_idedata: wrap json.loads on the prebuilt idedata.json in a
  try/except and re-raise as EsphomeError with a one-line diagnostic so
  the failure mode is a clean error instead of an unhandled
  JSONDecodeError stack trace. Update the surrounding comment to match
  the new behavior.
- CORE.prebuilt_dir docstring: drop the dead 'docs/architecture/...'
  pointer (no docs/ tree in this repo); point at esphome-docs#6600 and
  device-builder#572 instead.

New regression test:
- test_load_idedata_prebuilt_malformed_json_raises_esphomeerror

Updated test:
- test_get_ltchiptool_path_pio_penv now uses Scripts/ on win32 to match
  the new platform-aware lookup.

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.
