All Implemented Interfaces:

Serializable, junit.framework.Test

public class EventIdOptimizationDUnitTest
extends DistributedTestCase

This test verifies that eventId, while being sent across the network ( client to server, server to client and peer to peer) , goes as optimized byte-array. For client to server messages, the membership id part of event-id is not need to be sent with each event. Also, the threadId and sequenceId need not be sent as long if their value is small. This test has two servers and two clients , each connected to one server. The events with event-ids having specific values for thread-id and sequence-id are generated by client-1 and sent to server-1 and then to server-2 via p2p and then finally to client-2. It is verified that client-2 recieves the same values for thread-id and sequence-id.
