J. Nick Koston 0cb307aea5 Type the platform rejection, prefer bundled deps, parse manifests strictly
check_library_data's platform filter raises IncompatiblePlatform (an
InvalidLibrary subclass) so the arduino backend branches on the type
instead of substring-matching the message. The {"Wire": "*"} dict
shorthand resolves to the bundled library like PIO's
process_dependencies instead of a registry lookup. libArchive parses
booleans and true/false strings and warns on anything else (bool(str)
made "false" archive). A declared-but-falsy srcDir raises instead of
silently probing. The converter-drop warning names the missing requests,
and the bundled-walk comment states what PIO actually does.

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.
