Practical assignment
• List of connected clients on server
– At least 5 clients in parallel
– List with client info kept by server (ID, IP, port…)
– Client can request list of other connected clients
• Communication between client and client
– Connect to another client based on the information from server
– Transfer encrypted data packet with variable length (code from 2. seminar)
• Create (automatic) unit tests
– List clients (0, 1, N+1…)
– Test multiple clients connections to server (load test)
– Connection to client available / not available
– Encrypted data transferred from client to client (and back)
– …

Automate!
• Automate build
– Just Makefile without IDE
• Start server and multiple clients with script
– Port parameterization via cmd line?
• Execute all unit tests by single command
– Prepare your project for Continuous Integration (CI)

Make strong tests
• Packet repeater instead of isConnected()
– Test generated packet with content R
– Test uses client to send packet with R
– Server transform R into R’ (reverse bytes, append string…)
– Client receives R’ and return to Test
– Test verifies R’
• Test on localhost as well as separate machines
• Log data used during test
• Test with multiple clients, not just one
