"""
Test backwards compatibility for RAW Objects and Unpackers.
 
The ability to unpack all recorded Belle II events also with future release is
vital to be able to reconstruct the full Belle II dataset during the lifetime of the experiment
and after that.
This is the basis of unit tests which execute the unpackers and checks for the properties of the
unpacked sub-detector StoreArrays.
