in reply to Issues when testing module loading

When you test your modules, don't test if the prerequisites work - your Makefile.PL should test if they are available, and their specific test suites should check that they work the way they are expected to.

So just test use_ok 'Your::Module';.

(I know that doesn't answer the underlying question of how to test module loading; if you just want to silence these warnings, use no warnings qw(redefine prototype);)

    Thanks for that reply - yes if I were distributing things using a Makefile.PL then this would be a non-issue. But right now I distribute things as Debian packages, and raw .tar.gz files.

    (This particular case came up when I made a new release of my chronicle blog compiler.)

    Changing my test case to read as follows still fails though:

    #/usr/bin/perl -w # use strict; use warnings; no warnings "all"; use Test::More qw( no_plan ); BEGIN{ use_ok( 'CGI' ); } BEGIN{ use_ok( 'Date::Format' ); } BEGIN{ use_ok( 'POSIX' ); }
      my bad, warnings only effects the lexical scope, and the warnings are generated inside the POSIX module.

      One workaround is to explicitly only import a non-conflicting sub BEGIN{ use_ok( 'POSIX', 'setsid' ); }. Or use require_ok, which doesn't import anything.

      Or don't test for POSIX at all, it's been core since perl 5, and not likely to go away any time soon.

        I will stop testing for POSIX, as you suggest. (The test file is automatically generated; but I can add an exception to it without too much difficulty!)
