Hi Avinash,
Changes will be recorded in the AUDIT_LOG and AUDIT_PROPERTIES tables only when the History property is checked marked for the respective fields.
Please query these two tables and filter the result using this ENTITY as Test and ENTITY ID as the Test ID.
Example:
SELECT AU_USER,AU_TIME,AU_ACTION,AU_ENTITY_TYPE,AU_ENTITY_ID,AP_TABLE_NAME,AP_FIELD_NAME,AP_OLD_VALUE,AP_NEW_VALUE FROM AUDIT_LOG INNER JOIN AUDIT_PROPERTIES ON AUDIT_LOG.AU_ACTION_ID=AUDIT_PROPERTIES.AP_ACTION_ID where AU_ENTITY_ID='85624'
