Universal_Button support note:

This library targets Arduino-framework builds. The regular compile-test matrix
covers AVR, megaAVR, ESP32, ESP8266, RP2040, SAMD, STM32, and Teensy 4.x.
ESP32/FreeRTOS timing examples are ESP32-focused; other boards should use
Arduino millis() or supply their own TimeFn. See the root README for the
full supported/tested target notes.

This directory is intended for PlatformIO Test Runner and project tests.

Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.
