Test failover time period

Hi I am new here, sorry if I post duplicate question. I want to ask if I have a VM with a 7 days protection by Zerto, and I trigger a test failover, is there any time limitation of stop the failover test? What happen if I test over 7 days, will it be impact to the replication? And any alert or mail notification will send out for remind me to stop the failover test? Thanks.
