There ought to be a cheat sheet for fixing z3c.recipe.paster issues.

There are two buildouts involved: the main one, which you set up
yourself and run tests in, and the testing one, created in the setUp.
The testing one gets copies of eggs from the main one, for speed reasons
(I assume).

"Could not find PACKAGE-THAT-IS-RIGHT-THERE-ON-PYPI-LOOK-LOOK!" means
one of the packages copied from the main buildout into the testing one
has new dependencies that now need to be explicitly copied over too.

  Fix: add zc.buildout.testing.install('THAT-PACKAGE', test)

"AttributeError: 'NoneType' object has no attribute 'location'" means
one of those packages that used to be pulled in through dependencies is
no longer a dependency, is gone from the main buildout, and therefore
cannot be copied any more.

  Fix: remove zc.buildout.testing.install('THAT-PACKAGE', test)

I've a feeling this is not the first time I'm figuring this out.


This sort of manual babysitting is counter-productive and I wish I had
the time/energy to fix zc.buildout.testing.install() to pull in all the
requisite dependencies by itself.
