In OpenFlow, all stats are wrapped in a stats_request or stats_reply object. So, the table_stats object that you're looking for (there may be more than one in a reply) will be in the list returned from response.stats.
Take a look at how the ./tests/flow_stats.py test works. Also, fwiw, there is a forum to discuss oftest at http://oftest.openflowhub.org/ Hope this helps, - Rob .
