    SubscribeFieldToMQTTtopic subscriber = new SubscribeFieldToMQTTtopic(scheduler, field, changed, "homie/device123", false);
    CompletableFuture<@Nullable Void> future = subscriber.subscribeAndReceive(connection, 1000);
    // Simulate a received MQTT message
    subscriber.processMessage("ignored", "10".getBytes());
    // No timeout should happen
    future.get(50, TimeUnit.MILLISECONDS);
