    A service for testing Python code on multiple platforms and versions

    Hopefully a service like this already exists and I just haven't found
    it yet. If not it could be an idea for some kind soul(s) to pick up
    and run with ;-)

    As someone who writes and releases Python modules for the community, I
    find it difficult to have a decent level of confidence in the efficacy
    of my code on platforms and Python versions other than those that I
    own or use regularly. My documentation states that I support Python
    2.3 or higher. This ends up being more of a statement of good
    intentions than a one of fact.

    A case in point. A bug (in Python), that I believed to have been
    killed off after Python 2.2, resurfaced in a 2.4.x release of Python
    on PowerPC recently. As I don't own any PowerPC kit, it was very
    difficult to a) investigate the bug and b) create an effective fix for
    it in a timely fashion. Fortunately I'd come across it before so the
    fix was easy but it might not have been.

    While I realise one's code can never be perfect, you can cover for
    these sorts of eventualities fairly easily by running your software
    and unit tests under different environments. You'd also like to be
    able to do this on a continual basis rather than just once or twice.
    If this was done with some kind of automated testing and reporting so
    much the better. Bigger projects that take code quality seriously
    probably already have this sort of thing in place for their own
    purposes, but for smaller ones it just isn't possible.

    Wouldn't it be great to have a service/setup out there available for
    Python developers to access that covered a fairly broad base of
    possible Python installations for the purpose of improve overall code
    quality? Am I the only one that would find something like this useful?

    I would love to have such a tool, but have no idea how to create
    something like that.
    Something like a multi-virtual machine on a web server, that you launch
    in the night,
    and in the morning you would get a full report of all problems on the
    specific OSs
    (probably someone is going to say that this is impossible, but
    fortunately I'm not hindered by any knowledge ;-)

    cheers,
    Stef

      How about Buildbot? Here are some Python examples:

        You could run Buildbot on a bunch of virtual machines on your computer
        (assuming your computer is x86 and its OS is supported by something like
        Sun's VirtualBox or VMWare's offerings).
