 = Basic End-to-End Integration Test (basice2e)
 
 This test runs several servers and clients as a smoke test against the
-system. We runs a multi node, multi message, multi user test of the
+system. We run a multi node, multi message, multi user test of the
 system over multiple rounds all over network traffic. The basic
 structure is as follows:
 
-* 5 Nodes, BatchSize of 12
-* 3 Clients, each send 4 messages over several rounds:
+* 5 Nodes, BatchSize of 4
+* 5 Gateways, each connected to its own node
+* User Discovery Bot
+* Channel Bot
+* Client sending 2 dummy messages per second, in order to fill batches
+
+Then, the following tests are performed:
+
+* 2 Clients (9 and 18) register with the system and UDB by Email
+** These users look each other up on UDB
+** Test is successful if the first line of gold output file matches
+* The same 2 clients exchange E2E encrypted messages for 65s at a rate of 0.1msg/s
+** This will result in clients sending 6 messages to each other
+** It will also test that 2 rekeys on each side happen properly
+** Test is successful if all the aforementioned messages are accounted for.
+This is done by grep'ing the logs for sent messages, received messages, sent rekeys
+and received rekeys, and comparing to gold output of 6, 6, 2, 2
+* 4 Clients are started at two separate times and send messages to channel and to each other
 ** 2 messages to itself
-** 1 message to each of the other nodes
-* Each client asserts they receive their predefined messages
+** 1 message to each of the other clients
+** Test is successful if all gold output files match for client conversations:
+4-5, 5-6, 6-7, 7-4
 
 For now, we do nothing on assertion of crypto, we just assume
 api-level compliance with sending and receiving messages.
