IMPORTANT.
In this testcase i follow a different approach than usual: I don't use the full power of
QtTestTable and QtTestData. This is done deliberately because QtTestData uses a QDataStream
itself to handle its data. So it would be a bit inapropriate to fully rely on QtTestData in this
testcase.
I do use QString in QtTestData because this is thouroughly tested in the selftest.
