'''
A Python 3 only module that runs all the braille Tests and no other tests.

Does not run the doctests, unfortunately.  TODO: use mainTest somehow

This module produces a minimum of output which is most helpful
to people who are programming music21 on a screen reader.

For Bo-Cheng Jhan with my thanks.
