@Test
public void shouldReOrder() throws Exception {
    // given
    ClusterState clusterState = new ClusterState(asSet(member(0)));
    clusterState.queues.get(member(0)).add(new Election(member(0)));
    clusterState.queues.get(member(0)).add(new Heartbeat(member(0)));
    // when
    ClusterState reOrdered = new OutOfOrderDelivery(member(0)).advance(clusterState);
    // then
    assertEquals(new Heartbeat(member(0)), reOrdered.queues.get(member(0)).poll());
    assertEquals(new Election(member(0)), reOrdered.queues.get(member(0)).poll());
}

Example 2 with Heartbeat

use of org.neo4j.causalclustering.core.consensus.RaftMessages.Timeout.Heartbeat in project neo4j by neo4j.

// TODO: test that shows we don't commit for previous terms
@Test
public void leaderShouldSendHeartbeatsToAllClusterMembersOnReceiptOfHeartbeatTick() throws Exception {

    Leader leader = new Leader();
    // make sure it has quorum.
    leader.handle(new RaftMessages.HeartbeatResponse(member1), state, log());
    // when
    Outcome outcome = leader.handle(new Heartbeat(myself), state, log());
    // then
