    when(hazelcastInstance.getCluster()).thenReturn(cluster);
    Set<Member> members = asSet(makeMember(1), makeMember(2));
    when(cluster.getMembers()).thenReturn(members);
    // when
    client.start();
    jobScheduler.runJob();
    CoreTopology topology;
    for (int i = 0; i < 5; i++) {
        topology = client.coreServers();
        assertEquals(members.size(), topology.members().size());
    }
    // then
    verify(connector, times(1)).connectToHazelcast();
}

Example 2 with Cluster

@Override
public void writeResponse(ManagementCenterService mcs, JsonObject out) throws Exception {
    String resultString = "SUCCESS";
    try {
        Cluster cluster = mcs.getHazelcastInstance().getCluster();
        cluster.changeClusterState(getClusterState(state));
    } catch (Exception e) {
        ILogger logger = mcs.getHazelcastInstance().node.nodeEngine.getLogger(getClass());
        logger.warning("Cluster state can not be changed: ", e);
        resultString = FAILURE + e.getMessage();
    }
    JsonObject result = new JsonObject().add("result", resultString);
    out.add("result", result);
}

    MembershipListener membershipListener = mock(MembershipListener.class);
    String id = cluster.addMembershipListener(membershipListener);
    boolean removed = cluster.removeMembershipListener(id);
    assertTrue(removed);
    // now we add a member
    HazelcastInstance hz2 = factory.newHazelcastInstance();
    // and verify that the listener isn't called.
    verify(membershipListener, never()).memberAdded(any(MembershipEvent.class));
}
