Hello, I have to  made this challenge as last on of the OOP book Servers answering requests When a server node consumes a packet, it converts the payload to uppercase, then sends that back to the sender of the request. This is yet another subclass which redefines the consume: method, but this time the node is stateless, so we have no initialization or accessor methods to write: KANetworkNode subclass: #KANetworkServer instanceVariableNames: '' classVariableNames: '' category: 'NetworkSimulator-Nodes' KANetworkServer >> consume: aPacket | response | response := aPacket payload asUppercase. self send: (KANetworkPacket from: self address to: aPacket sourceAddress payload: response) Define a test for the behavior of server nodes. I tried but I miss something so far as I have this : testSendToServer     | packet ping pong link |     packet := KANetworkPacket from: #ping to: #pong payload: #ball.     ping := net nodeAt: #ping.     pong := net nodeAt: #pong.     link := net linkFrom: #ping to: #pong.     ping send: packet.     pong consume: packet. but whatever I tried I cannot think of a test that works. I tried assert:  ping payload equals: #BALL assert: ping arrievedpackages equals; 1 but they all fail It looks like ping does not recieve the package back. What do I do wrong or what can I test better ? my code so far : https://github.com/RoelofWobben/network and the problem is the testToServerTest that I cannot make work Regards, Roelof
