Sup redundancy and fail over testing should be done during the testing phase of the equipment and/or after major IOS upgrade to make sure it actually works. Once it has been determined that it works with no issue, there is no need to do it every so often.
Hi netsquant, You dont failover them unless you are testing the same in a scheduled test case scenario. You can check the status regularly using the gold feature general online diagnostics feature however as a best practise.
