Unit Tests missing

[Sergiu-Cosmin]

hello,

we would love to use your library for our product but our acceptance criteria states that the external libraries that we want to use need to have some kind of tests (Unit Tests or at least some UI Tests) to get a "guarantee" of quality.

may I ask why are there no unit tests present in this library ?
