-# What does this implement/fix?
-
-Removes redundant ESP32 Arduino test files for the `opentherm` component and cleans up redundant preprocessor conditionals. The ESP-IDF tests provide complete coverage since the opentherm component has no framework-specific implementation differences for ESP32.
-
-Also fixes incorrect preprocessor conditionals - changes `#if defined(ESP32) || defined(USE_ESP_IDF)` to `#ifdef USE_ESP32`. The macro `ESP32` is only defined for the original ESP32 variant, while `USE_ESP32` covers all ESP32 variants (C3, S2, S3, etc.). The `|| defined(USE_ESP_IDF)` was unnecessary since ESP-IDF can only run on ESP32 platforms.
-
-## Background
-
-As part of the ongoing effort to reduce Arduino-specific test redundancy (esphome/backlog#66), this PR removes ESP32 Arduino tests that duplicate IDF test coverage.
-
-**Analysis of opentherm component:**
-- Previously used `#if defined(ESP32) || defined(USE_ESP_IDF)` to check for ESP32 **platform**
-- This was incorrect: `ESP32` is only defined for the original ESP32 variant, not C3/S2/S3
-- Changed to `#ifdef USE_ESP32` which covers all ESP32 variants
-- The `|| defined(USE_ESP_IDF)` part was unnecessary since ESP-IDF can only run on ESP32 platforms
-- ESP32 timer APIs (`timer_init`, `timer_set_counter_value`, `timer_isr_callback_add`) are ESP-IDF APIs
-- These timer APIs work identically in both Arduino and ESP-IDF frameworks since Arduino is now built on ESP-IDF
-- Only ESP8266 has framework-specific code (using Arduino's `timer1_*` functions)
-- ESP32 implementation is identical across frameworks

-## Changes
-
-### Code Cleanup
-
-**OpenTherm component:**
-- Fixed incorrect `#if defined(ESP32) || defined(USE_ESP_IDF)` to `#ifdef USE_ESP32` in:
-  - `esphome/components/opentherm/opentherm.h` (3 locations)
-  - `esphome/components/opentherm/opentherm.cpp` (4 locations)
-- `ESP32` is only defined for the original ESP32 variant, not C3/S2/S3
-- `USE_ESP32` correctly covers all ESP32 variants
-- The `|| defined(USE_ESP_IDF)` part was unnecessary since ESP-IDF can only be defined on ESP32 platforms
-
-### Test Files Removed
-
-- `tests/components/opentherm/test.esp32-ard.yaml`
-- `tests/components/opentherm/test.esp32-c3-ard.yaml`
-
-### Test Coverage Maintained
-
-ESP-IDF test files remain and cover both frameworks:
-- `tests/components/opentherm/test.esp32-idf.yaml`
-- `tests/components/opentherm/test.esp32-c3-idf.yaml`
-
-### Platform-Specific Tests Retained
-
-Arduino tests remain for ESP8266 (uses Arduino-specific `timer1_*` functions):
-- `tests/components/opentherm/test.esp8266-ard.yaml`
-
-## Benefits
-
-- **Reduces CI test time** - 2 fewer redundant test configurations
-- **Simplifies code** - Removes redundant preprocessor conditionals
-- **Maintains coverage** - IDF tests cover both frameworks for ESP32
