J. Nick Koston 57e738adf8 Simplify the library backend: share the dependency filter, drop the request-key drop diff, dedupe test scaffolding
Validate manifest shape once in the converter (every backend dereferences
data/build), share the InvalidLibrary filter as dependency_is_usable(),
and let the walk's reconciliation own version-less drop reporting so the
arduino backend's request-key diff, owner-no-version warning, and
node_key plumbing all go away. One memoized _provided() predicate now
answers bundled-name checks at all three sites. Tests gain shared
scaffold helpers and lose the assertions that pinned deleted messages.

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
test2.yaml ESP32 ethernet esp32_ble_tracker
test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None
test5.yaml ESP32 wifi ble_server
test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
