The developers of the software are not the only folks who run its tests.
 In particular, "downstream" consumers need to run them, too,  Keeping
the burden of running them as low as possible helps make sure that folks
who are considering using the project can run its tests easily, as well
as tools like 'cheesecake',

If we want to encourage "casual" contributors to test the code (e.g.,
users who finnd a bug, or help out during a bug day) we need to make it
easy and documented how to do so.  The "hacking" page I wrote for
zope.event is aimed at such contributors, and describes both ways to run
the tests:


Finally, keeeping the required infrastructure for running the ZTK tests
minima is essential to the topic of this thread, which is helping
Lennart's efforts porting to Zope3.  Right now, their reliance on
zc.buildout + zope.testing for running the tests is the major blocker to
porting the other ZTK packages to Python 3.
