tests_require doesn't really do anything.  It is used solely by  
setuptools at setup time.  It doesn't create any meta data that can  
be used by any other test runner, like ours.  IMO, it is useless.   
See the discussion of this a while back on the distutils sig mailing  
list.

The easiest way to start is to try creating package buildouts that  
don't use a Zope checkout and seeing if you can make them work.  For  
example, check out the zope.component buildout, modify it so that it  
doesn't exclude the zcml tests, and see if you can get the tests to  
pass.  You'll notice that:

- zope.security should list zope.location as a depenency

- you'll end up with a depenency on zope.app.container, which doesn't  
exist as an egg or project.

When these are fixed, there are probably lots of other issues.

I think we're at the point now where we actually need to try and make  
things work.  If you do, you'll discover, as I did a few weeks ago,  
that tests_require doesn't do anything useful.

I would *greatly* appreciate it if you could work with Alex Heavner.  
He's now working on getting the zc.sharing buildout working without a  
zope3 checkout.  He's starting with the tests.  He could really use  
some help and I'll be at PyCon for the next few days. Note that  
Alex's initial goal is to get this working without getting the  
dependencies right. He's just listing all of the eggs you and he have  
made and trying to get the tests to pass.
