Use the chutney Tor network simulator in our test suite
See parent ticket (#9519 (closed)) for the rationale.
We may want to use chutney to simulate the Tor network for increased determinism in our test suite.
The Tor network is a large part of the test suite’s indeterminism, both from transient network issues when communicating with the Tor network (or internal issues, e.g. bad circuits), and from the chosen exit node being blocked. Simulating the Tor network on the testing host would eliminate all such issues.
There is, however, a potential for making the testing host
blacklisted/blocked if services identifies the repeated connections as
irc.oftc.net blocks lizard because of the multiple IRC
connections made per hour, potentially). If that is a problem, #9520 (closed)
would solve that.
