@Test
public void testRouteHint() {
    Cluster cluster = VoldemortTestConstants.getNineNodeCluster();
    HintedHandoffStrategy handoffStrategy = new HandoffToAnyStrategy(cluster, false, 0);
    for (Node origin : cluster.getNodes()) {
        List<Node> nodes = handoffStrategy.routeHint(origin);
        assertTrue("hint preflist is correctly sized", nodes.size() == cluster.getNumberOfNodes() - 1);
        assertFalse("hint preflist doesn't include self", nodes.contains(origin));
    }
