From: Jithu Joseph <[email protected]> Add tracing support for the SBAF IFS tests, which may be useful for debugging systems that fail these tests. Log details like test content batch number, SBAF bundle ID, program index and the exact errors or warnings encountered by each HT thread during the test.
