J. Nick Koston 8e6af6aa8c Name the manifest in every dependency diagnostic, warn where no backend can recover
normalize_dependencies' parameter is manifest_name (the dict branch
already binds owner to a package owner), and the arduino call site
passes the library's name so its unrecognized-entry warning stops
saying 'of manifest'. A version-less dependency warns when the backend
declares no provides tree (espidf/zephyr/nrf52 have no post-emit
pickup), and the shared walk mirrors the typed IncompatiblePlatform
branch: routine platform skips stay at debug, any other InvalidLibrary
cause warns naming the component. The two real-converter tests pin
ESPHOME_DATA_DIR to tmp_path so an ambient data dir cannot leak in.

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.
