Tests use the test program in this directory named ``prog``.

Any tabs in the input line simulate the user pressing tab.
    For example, ``self.sh.run_command('prog basic "b\tr\t')`` will
    simulate having the user:

1. Type ``prog basic "b``
    2. Push tab, which returns ``['bar', 'baz']``, filling in ``a``
    3. Type ``r``
    4. Push tab, which returns ``['bar']``, filling in ``" ``
    5. Push enter, submitting ``prog basic "bar" ``

The end result should be ``bar`` being printed to the screen.
