While your advice for when to write tests seems spot on—before writing (much) code, and when bugs are found—your advice for when not to write them seems suspect. Even when a complete, working application is in place, it's appropriate to buttress it with tests—they will help with maintenance, so that changes can be seen not to break existing behaviour, and, well, testing, perhaps revealing that an application that seemed to be both complete and working is neither. Since writing tests, especially in Perl, can be very cheap, and need not be done all at once, it seems harmless at worst.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.

    [tye]: Is it just me, or do most python things have terrible logging/errors?
    [LanX]: but but but ... the errors are nicely formatted!
    [tye]: 1) The python stack traces show you the names of variables, not the values of variables. Almost never informative.
    [LanX]: do you have a py job now?
    [tye]: Right now I have errors trying to fetch stuff from graphite. It says 'apps not ready, check startup logs'. I eventually find the startup logs and see 'no apps found'. Looking for fixes to this problem...
    [LanX]: no idea ... ask py monks! ;-p
    [tye]: it turns out that this can be caused by almost anything going wrong. If you want to know what caused the problem, you have to try to load each app by-hand to see what problems it is having, because none of those will be logged.
    [tye]: No, I write more Perl than py at work. But I have to deal with plenty of py things.
    [tye]: py monks would just be offended.
