[tor-commits] [tor/master] Practracker: add an integration test.

commit 8d3f3e5d30fa97479bc218a2896cb538ea220514
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Tue Jul 30 12:07:40 2019 -0400

    Practracker: add an integration test.
    
    This test runs practracker with a set of 0 thresholds, to make sure
    that it enumerates all its values right.  It tries running with an
    empty exceptions file, and with an exceptions file that covers
    _some_ of the data, and it makes sure that the outputs are as expected.
