[gentoo-dev] Packages with optional test dependencies

[Michał Górny]

Hello,

There are some Python packages which have a bunch of optional tests
utilizing external packages. For example, the dev-python/logilab-common
runs a few additional tests if dev-python/egenix-mx-base is installed;
if the package is not installed, it just skips those tests.

Those tests can't be really considered 'heavy' or in any way suggesting
use of an additional USE flag.

Do you believe that the ebuilds should:

a) depend on all optional test dependencies conditionally to USE=test,
   therefore always requesting the widest (and consistent) testing,

b) not depend on the optional test dependencies, resulting in less
   dependencies for most users but also a bit inconsistent test
   experience,

c) put the optional test dependencies behind an additional USE flag?
