An AssertionError is documented under http://docs.python.org/library/exceptions.html#exceptions.AssertionError:

Raised when an assert statement fails.

Your unittest is asserting that SetTarget will return something that is boolean True; however, your method is returning {}, which is equivalent to boolean False, causing the AssertionError. To fix this, either test if SetTarget has returned {} or change it to return something that will be interpreted as True.

If you're wondering why the device code is not working, it's because you're running your unittests before starting the device - and if a unittest fails, your script will stop there.
