  • I tend to use "classic" Test, which can still do the "silencing extra diagnostics" trick; just output the extra diagnostics on STDOUT, and keep STDERR for serious stuff (and perl warnings, of course).

    when run from "make test" or "prove", the STDOUT output is hidden; when run from "make test TEST_VERBOSE=1" or "prove -v", or run directly from the commandline as "./testname.t", the STDOUT diagnostics become visible.

    works great ;)

    • I tend to use "classic" Test ...

      Do you mean the ancient Test.pm? If so, you're missing out on all of the improvements made in the testing world over the years. Test.pm should only be there for legacy support.

      If you must use that interface, at least consider using Schwern's Test::Legacy [cpan.org] module. This will allow you to keep that interface but still use other testing modules. Of course, that changes your diagnostic output and breaks what you've described. However, diagnostics are a small, small price to pay for using the rest of Perl

      • yeah, I do mean that ancient module. and I know there are many goodies available if I was to catch up ;)

        In SpamAssassin, we have a project philosophy of attempting to keep our CPAN dependencies at a minimum, and we support perl 5.6.1 as a platform. even Test::More didn't arrive until 5.6.2, unfortunately...

        I should really use Test::More for my other modules, though.

        'Of course, that changes your diagnostic output and breaks what you've described.'

        really? are you saying the newer test modules remove this (very useful) behaviour? that seems a pity!

          Assuming you have a compatible license, you can do what the darcs project does: Ship a private copy of Test::More with the test suite suite. This eliminates problems between your test suite and different versions of Test::More as well.
