the class ReactiveKafkaConsumerTest method testOffsetResetLatest.

@Test
public void testOffsetResetLatest() throws Exception {
    int count = 10;
    sendMessages(0, count);
    String groupId = UUID.randomUUID().toString();
    MapBasedConfig config = createConsumerConfig(groupId).with("topic", topic).with(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "latest");
    SingletonInstance<KafkaConsumerRebalanceListener> listeners = new SingletonInstance<>(groupId, getKafkaConsumerRebalanceListenerAwaitingAssignation());
    source = new KafkaSource<>(vertx, groupId, new KafkaConnectorIncomingConfiguration(config), listeners, CountKafkaCdiEvents.noCdiEvents, UnsatisfiedInstance.instance(), 0);
    AssertSubscriber<IncomingKafkaRecord<Integer, String>> subscriber = source.getStream().invoke(this::onReceive).subscribe().withSubscriber(AssertSubscriber.create(10));
    await().until(() -> {
        Map<TopicPartition, Long> map = source.getConsumer().getPositions().await().indefinitely();
        return map.values().stream().mapToLong(l -> l).sum() == 10;
    });
    subscriber.assertSubscribed().assertHasNotReceivedAnyItem();
    sendMessages(count, count);
    await().untilAsserted(() -> assertThat(subscriber.getItems()).hasSize(count));
    await().until(() -> {
        Map<TopicPartition, Long> map = source.getConsumer().getPositions().await().indefinitely();
        return map.values().stream().mapToLong(l -> l).sum() == 20;
