Hmm. So I'm definitely not running a server right now but I'm getting this on the first test

CF416-03/test :) $ python servertests.py -p 42426 -s localhost
running test "is_server_running"
Try to connect to the server, send a join and expect a conn
[join|tom ]
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
[join|tom ][exit]
test passed

It looks like the rest of the tests are failing though...
If I'm reading it right, it looks like [join|tom ] is sent before telnet establishes a connection. Hmm. Probably not a big deal since most everybody who is using this test will probably actually have a server running :p

Should be fixed now.

So, I haven't done much of the networking yet but have been setting up classes and all that good stuff, so I'm not quite ready to write tests, but I did write up a bunch of strings to test if I was parsing and getting correct error messages. I'm going to post them here just incase anybody wants them, and then try to add some of them to the test script. There are a few places in the spec where I'm not sure what error we should be producing, I'll comment there.

good to make sure your server won't die
