I have an class that should connect to a server and just wait for
responses. Here’s the class, it’s very basic
class Connection
def initialize(host, port)
@host, @port = host, port
@server = TCPSocket.new @host, @port
listen
end
private
def listen
Thread.new do
while cmd = @server.gets
puts cmd
end
end
end
end
This seems to work if I connect to a live server. It’s not working
perfectly, because it only gets a couple of responses and then quits
before it has all of them. However, if do t = Thread.new… and then
call t.join after the thread block, it just hangs there. So I’m not
sure what to do about that.
Secondly, I don’t know how to mock up the server. I have this class:
class TCPSocket
def gets
while $server_messages.empty?
# just sit and do nothing
end
$server_messages.shift
end
end
and in my unit tests I add a string to $server_messages. If I join my
thread in Connection#listen it just hangs, and if I don’t join, it
just exits without getting any messages. How can I listen for
arbitrary messages in another thread, and how can I mock up the
server?
