J. Nick Koston 864d31aa65 [core] Put ComponentMarker outside the IIFE as a visual bracket
The marker comment was being emitted as the first line *inside* each
IIFE:

  []() {
    // === logger ===
    // logger:
    //   ...
    ...
  }();

That works but buries the component label inside the lambda body, so
scanning generated main.cpp to find "where does component X's setup
live" is harder than it needs to be. Emit the marker before and after
the IIFE instead:

  // === logger ===
  []() {
    // logger:
    //   ...
    ...
  }();
  // === logger ===

Comment-only components (e.g. sha256, async_tcp, empty platforms like
binary_sensor:) don't grow a useless trailing duplicate marker —
when there's no IIFE to bracket, the marker is emitted once.

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
