Integration tests with fake ssh channel and console

[boxdot]

It is very tedious to test the bot against a running instance of Gerrit. It should rather simple to write a ssh server which will just replay a file on some commands. Gerrit can be simulated as output to stdout and input from stdin. An integration test is then a triple of files: one is replayed on stdin of the bot, one on the output of the ssh server, and the third one is used as expected output of the bot.

Is this addressed by #81 in your opinion? There’s still a real Gerrit (in a container) but events are created automatically.
