Moved protected properties to abstract test class and updated some comments.
Reordered the checks in saveDataTable in the persistence adapters. So now first the table name and second the datatable content is checked. It seems to make more senso to check the table to put the data into vbefore parsing the datatable itself.
Fixed missing require-statement in abstract persistence adapter. Translated comments into english. Persistence adapters now can handle tables where the primary key is not "UUID" in datatable functions.
