J. Nick Koston 612775908e Never substitute a URL-pinned dependency; rename the header-suffix set; warn on real bundled suppression
A dependency whose version is a repository URL names one specific
source, so it is now detected before the backend-provided skip and
resolves as git instead of being replaced by the bundled copy. The
library header-suffix set becomes LIBRARY_HEADER_SUFFIXES so it cannot
shadow esphome.const's narrower HEADER_FILE_EXTENSIONS. Suppressing a
genuinely bundled name on an external short-name match warns (an
accidental collision would surface as link errors), a converted library
with no sources and no headers warns by name, and the walk's
unreachable nameless-dependency check is gone.

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.
