Alright. I've pushed the updated version. Let's see.

No.

Only if you do some mocking in a unity test.

But you can record and then replay multitouch events straight out of a /dev/input/eventX file using utouch-evemu-tools (for the recording) and libutouch-evemu1 in your test. But it would be a functional or integration test since several layers would be involved (events coming out of /dev/input/eventX into xserver and then sent as XInput2 events to compiz)
