IDS mode shouldn't log without there being alerts, however the test rule 
you describe makes EVERY tcp/ip packet an alert.

alert tcp any any -> any any should more-or-less turn snort into a "log 
everything", with the only exception being that udp and icmp traffic won't 
get logged.

So what makes you conclude that there are "no alerts"?
