Hi all,

I've retitled this thread to reflect the current topic, and CC'd the open-bio-l
mailing list as Raoul suggested. Can we continue the discussion there?

Note that this is a small Amazon cloud machine, and doesn't actually run
the tests itself (that would require a more expensive machine due to the
higher load). Instead we need client machines (covering a range of OS,
Python version etc) whose run-time is donated (currently by Biopython
developers or their employers).

When setting up http://testing.open-bio.org/ the intention was to have
it host other Bio* projects too - and they don't have to be using the
buildbot software (but they could if they wanted to).

This is something we're pushing much more with Biopython in recent
years (a depressing amount of legacy code had no tests when I first
got involved, things are a lot better now). For any new code contributions
we do ask for tests and minimal documentation (and try and work
with the contributor to help this happen).

With Biopython we're starting to make more use of testable docs
(Python's doctest system) which is really good I think. But you are
right, you need proper unit tests AS WELL. With our doctests,
the primary aim is to be useful documentation (which can double
as a basic functional test).

I'm not quite following - it may be a terminology difference.

Same here :)
