Provide tests for a selection of method
The core algorithm is still not tested because I do not see how I could get the required objects in the necessary state. The unfortunate thing about the implemented selection algorithms is that they rely on an open editor for a normal execution, which seems to be hard to set up for a unit test. Any feedback and help on this is highly appreciated!
