I'm playing with a solution that involves the use of the 'vcr' package, which as its name implies (well, at least for us, um, mature programmers ;) is a facility to record and replay HTTP traffic. It's compatible with both Python 2 and 3 and is available on the Cheeseshop. So the basic idea is to set up an MM3 installation (`tox --notest -r` suffices), then start up its REST server with a fresh mailman.db, and run the test suite against it. This will capture the traffic in a yaml file, which we could ship with mailman.client. Then to run the test suite, you'd use vcr in replay mode against the captured yaml file. Any time the API changes, you'd have to re-record the traffic against a fresh database. I have a branch that's working in this direction and it's promising, but I've also had to rewrite the testing infrastructure for mailman.client, and make some other changes. It also points out what I think are some bugs in Mailman core, so I'm working those out on my py3 branch in parallel. It's not yet ready for review, but if you want to keep an eye on things, look here: lp:~barry/mailman.client/bilingual Feel free to provide feedback on the approach, or the changes so far, but I will submit a merge proposal when/if it's ready to go. Cheers, -Barry
