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. More information about PlatformIO Unit Testing: - https://docs.platformio.org/en/latest/advanced/unit-testing/index.html
