         Run them using `script/test_build_components`. Use `-c <component>` to test specific components and `-t <target>` for specific platforms.
-    *   **Testing All Components Together:** To verify that all components can be tested together without ID conflicts or configuration issues, use:
-        ```bash
-        ./script/test_component_grouping.py -e config --all
-        ```
-        This tests all components in a single build to catch conflicts that might not appear when testing components individually. Use `-e config` for fast configuration validation, or `-e compile` for full compilation testing.
 *   **Debugging and Troubleshooting:**
     *   **Debug Tools:**
         - `esphome config <file>.yaml` to validate configuration.
