Answer 1

How can I send fake data to the accelerometer from a unit test?

AFAIK, you can't.

Have your shaker logic accept a pluggable data source. In the unit test, supply a mock. In production, supply a wrapper around the accelerometer.

Or, don't worry about unit testing the shaker itself, but rather worry about unit testing things that use the shaker, and create a mock shaker.
