J. Nick Koston 5f8e991ed8 [api] Populate schema defaults for transitive cpp test deps; add json override
- script/build_helpers.py: when injecting a non-MULTI_CONF component
  into the post-validation config, run its CONFIG_SCHEMA with {} so
  defaults are populated. Without this, socket got config = {} and
  socket.FILTER_SOURCE_FILES crashed with KeyError on
  'implementation' (the schema's defaulted key was never filled in).
  Falls back to {} if the schema can't validate empty input.

- tests/components/json/__init__.py: enable codegen for json so its
  to_code runs during cpp unit test builds, registering the
  ArduinoJson library. Required for any api dep test, since
  json_util.cpp #includes <ArduinoJson.h>.

Locally verified 'script/cpp_unit_test.py api' now compiles and runs;
ProtoMacVarint test suite (9 cases) passes.

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
