• Tom Metro commented on A Date with CPAN, Update #3: Golden Jubilee

  >hardcoding test results has other problems

  We always coach developers to use hard coded test data to the extent practical. When writing tests you have to unlearn a lot of DRY principles. We tolerate a lot more repetition, and factor it out sparingly.

  There are two main reasons why you do this:
  1. Any bit of clever calculation in your test could could be wrong. Hard coded values are easy to hand verify.
  2. Your test should read like an example of how to use your API, and having lots of layers of indirection and data generators makes the code less readable.

  It looks like it's there already! I'm looking forward to converting over to using these new functions: timegm_posix and timelocal_posix. Should make my job much easier. :-)

  What you're suggesting can be good advice—I certainly agree that repeating yourself in unit tests is often preferable to being too clever in them, for instance—but I don't believe it is always good advice. Unfortunately, I think a proper response is beyond a comment here; perhaps I'll compose a larger blog post on this very topic in order to discuss the pros and cons.

  And there's also Acme::SvGrow from back in the day, which uses either Data::Peek::DGrow, or the `push( '.' . $length)` approach.

  I implore everyone to read this post, made just days after the one I am replying to. Among other things, the author who was quite *literally* there, discusses the "success" of the Python3 transition.
