Provide unittests for this lib

[Jovan-ux]

Sorry if I'm boring you again. I wanted to ask if there are unittests (e.g. gtest or similar) for this lib? If you can provide something, I would be happy to build a project out of it with CMAKE&GTEST and play it back.

So far I haven't had any problems with the code, everything works as it should. Nevertheless, unit tests would of course be an enrichment. Who knows what else is coming, Dave.
