ORA-19903: test recovery not allowed when recovering to new incarnation
Cause : Either a new incarnation was set using RMAN's RESET DATABASE command for a control file that was CURRENT, or the control file is from a prior incarnation. As recovery to a new incarnation requires changing the control file, test recovery is not allowed.

Perform actual recovery or RESET DATABASE to incarnation that was last opened using the control file to do test recovery.
