I am working on a project that needs to do some modifications on the source code of Tor, to add functionalities to Tor relay. To debug I used chutney to setup Tor network locally, and checked the logs of the relay. But it is still painful and slow: I need to restart the script, and wait the network to be up every time I make changes. My question is: is there any fast way to test/debug the functionalities of Tor relay? 

Thanks!
