------------------
A Simple Test Plan - script version

I recommend using a shell script test_plan.sh to create an automated
test plan; so, you don't have to redo all the tests manually every time
you change your client/server.

Since your client treats each input line as a separate message, you can
automate testing of your client/server using a shell script that contains
your test inputs as "here" documents ("man bash").

#!/bin/sh -u
# This script might be named test_plan.sh
# This script runs tests against the $CLIENT in the current directory.

CLIENT=./client                   # name of client executable
SERVERIP=10.50.15.101             # server IP address
PORT=5000                         # server port
RUN=" $CLIENT $SERVERIP $PORT "   # how to run the client

CLIENTIP=10.50.15.102             # valid IP of another client for /msg
SLEEP=2                           # seconds to sleep between tests

echo "=============================================================="
echo "Test 1: a regular message broadcast to all clients"
echo "=============================================================="

cat <<EOF | $RUN
This is test message one.
This is test message two.
Short message.
Longer message that goes on a bit wider right up to about 80 columns wide or so.
EOF

sleep $SLEEP   # allow server to catch up 

echo "=============================================================="
echo "Test 2: a /msg with a valid IP address"
echo "=============================================================="

# a) test upper/lower case
# b) test random amounts of blanks/tabs on the line

cat <<EOF | $RUN
/msg $CLIENTIP This is a test message 1.
/MSG $CLIENTIP This is a test message 2.
/MsG $CLIENTIP This is a test message 3.
/msg  $CLIENTIP   This is a test message 4.
/msg   	$CLIENTIP 	   This is a test message 5.
    /msg 	 	 $CLIENTIP    	 This is a test message 6.
EOF

sleep $SLEEP   # allow server to catch up
