[TASK] Add functional test cases to DataHandler (workspace)
In addition to the functional test cases for data handling in
live, these test cases re-use the test scenarios to check the
behaviour in a particular workspace.
The current assertions only check the current behaviour. Parts
that are identified as faults are marked out with the ignore
operator "\*" in the CSV files.
Thus, these tests shall be used to compare the current state
with the target state in combination with accordant bug-fixes
for workspace data handling.
