/**
 * <p>Represents the input of a <code>TestFailover</code> operation which tests automatic
 *             failover on a specified node group (called shard in the console) in a replication group
 *             (called cluster in the console).</p>
 *          <p>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. </p>
 *          <p class="title">
 *             <b>Note the following</b>
 *          </p>
 *          <ul>
 *             <li>
 *                <p>A customer can use this operation to test automatic failover on up to 15 shards
 *                     (called node groups in the ElastiCache API and Amazon CLI) in any rolling
 *                     24-hour period.</p>
 *             </li>
 *             <li>
 *                <p>If calling this operation on shards in different clusters (called replication
 *                     groups in the API and CLI), the calls can be made concurrently.</p>
 *                <p> </p>
 *             </li>
 *             <li>
 *                <p>If calling this operation multiple times on different shards in the same Valkey or Redis OSS (cluster mode enabled) replication group, the first node replacement must
 *                     complete before a subsequent call can be made.</p>
 *             </li>
 *             <li>
 *                <p>To determine whether the node replacement is complete you can check Events
 *                     using the Amazon ElastiCache console, the Amazon CLI, or the ElastiCache API.
