More clarity on use case

The problem we have today is that if 1 of these 244 fails, I'd like to capture some information(flows on OVS, data on ODL etc.) at that point. but we don't get control back till entire suite including the teardown/cleanup is done. if we can get a hook to capture information in case of failure, before teardown is done, that is also good enough.
