// Represents the input of a TestFailover operation which test automatic failover
// on a specified node group (called shard in the console) in a replication group
// (called cluster in the console). This API is designed for testing the behavior
// of your application in case of ElastiCache failover. It is not designed to be an
// operational tool for initiating a failover to overcome a problem you may have
// with the cluster. Moreover, in certain conditions such as large-scale
// operational events, Amazon may block this API. Note the following
// - A customer can use this operation to test automatic failover on up to 5
// shards (called node groups in the ElastiCache API and Amazon CLI) in any rolling
// 24-hour period.
// - If calling this operation on shards in different clusters (called
// replication groups in the API and CLI), the calls can be made concurrently.
// - If calling this operation multiple times on different shards in the same
// Redis (cluster mode enabled) replication group, the first node replacement must
// complete before a subsequent call can be made.
// - To determine whether the node replacement is complete you can check Events
// using the Amazon ElastiCache console, the Amazon CLI, or the ElastiCache API.
// Look for the following automatic failover related events, listed here in order
// of occurrance:
// - Replication group message: Test Failover API called for node group
// - Cache cluster message: Failover from primary node to replica node completed
// - Replication group message: Failover from primary node to replica node
// completed
// - Cache cluster message: Recovering cache nodes
// - Cache cluster message: Finished recovery for cache nodes For more
// information see:
// - Viewing ElastiCache Events (https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/ECEvents.Viewing.html)
// in the ElastiCache User Guide
// - DescribeEvents (https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_DescribeEvents.html)
