@ortex, all my functionality is covered by tests, but the codecov ignores it. Tests for which blocks of code do I need to write in order to pass the codecov check for patch coverage with tests?

This is because there aren't happy path for setters. In tests there are always thrown exception.

But I don't think we need tests for that, especially since we going to rework configs in #110

Thanks for PR!
