So, the first bits for improving chutney would be to automate the
network generation as much as possible (leaving no loose ends)?

Now, we want chutney to be robust enough to encompass all the manual
that is mentioned above & automate it as much as possible or atleast
print the tasks to be performed by the tester sequentially. We would
need a set of static reliable web pages if we want to automate the
traffic testing?

Also, we would parse the log files for errors or warnings so that
we dont have to manually check for them.

  * Construct a circuit to an exit which allows port 80 and request a
site through it.
  * Do the same for an exit which rejects port 80.
  * Construct a one-hop circuit through an exit.
  * Try to use a circuit that runs through a bridge.
  * Let tor pick the path of a circuit and assert that the first
relay's a guard and the last is an exit.
  * Attempt to request a page from a hidden service.
  * Host a hidden service and request something from ourselves.
  * Act as a relay and try to construct a circuit that includes ourselves.
  * ... etc...

As Damian listed down all the tests one needs to carry out for actual
network testing (keeping in mind unreliability of the network at times),
what all additional tests would we like chutney to have?
