Unit test

[kronenthaler]

In order to tackle more interesting and deeper refactors in necessary to increase the coverage of the unit test so the changes can be made with a higher level of confidence.

The goal is to achieve at least 70-80% coverage in the package before starting any refactor in the affected package(s)
