+## Test failover behavior
+
+You can test your app's failover behavior in Redis Cloud by running a failover test. A failover test in Redis Cloud simulates a controlled disruption such as an endpoint migration, node failure, or cluster outage to confirm that your app can reconnect, recover, and continue operating without data loss. These tests are a critical part of validating high-availability and disaster recovery, ensuring that applications meet recovery time and recovery point objectives.
