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.
