Hi,
One of easy way maybe Data Refresh(expdp and impdp for oracle database).
You will get DEV Database dump(PPM and Dataware house) and import them to TEST environment.
Of course, you need to remap scheme to import them.
After import dump to TEST, you will lose all existing data in TEST. So you may need to take backup some objects in TEST before import. (To take backup data, you can use content package or XOG)
For jasper reports, you may be able to use export function for jasper report.
You will export jasper report from DEV and import it to TEST.
