You'll find some tickets already exist in the tracker.  For example,

  http://twistedmatrix.com/trac/ticket/3493
  http://twistedmatrix.com/trac/ticket/3431
  http://twistedmatrix.com/trac/ticket/3424
  http://twistedmatrix.com/trac/ticket/3231
  http://twistedmatrix.com/trac/ticket/3153

For other issues, I would lean towards filing a ticket per test_*.py file.
However, this is just a general rule of thumb.  You may find it easy to fix
several test_*.py files at once with one set of changes, or you may find
that the fixes for one set of deprecations from a single test file are
totally unrelated to another set of fixes for other deprecations (cases in
which I would file just one ticket or multiple tickets, respectively).  So
feel free to exercise your own judgment.  We won't bite your head off if
we disagree with your decision, but we might ask you to split one patch
into two or more pieces.

One thing that's probably worth watching out for is that there are a couple
large, old Conch branches outstanding.  Changes to Conch's test suite may
conflict with these branches.  I wouldn't let this stop you from fixing
things in Conch, but it would probably be best to try to coordinate with
Paul Swartz before digging in too deeply.
