in thread Optional modules for tests?

Thanks for the response.

I've been experimenting with this and have minimized my test code to the following:

use Test::More tests => 1; SKIP: { eval{ require Data::Dummy }; skip "Data::Dummy not installed", 2 if $@; ok( 1 ); }
This works fine when the required module is present, but in the case of a non-existant module (such as with the above Data::Dummy), the following is reported:
C:\>nmake test Microsoft (R) Program Maintenance Utility Version 1.50 Copyright (c) Microsoft Corp 1988-94. All rights reserved. C:\Perl\bin\perl.exe "-MExtUtils::Command::MM" "-e" "test_harn +ess(0, 'blib\lib', 'blib\arch')" t\test.t t\test....# Looks like you planned 1 tests but ran 1 extra. t\test....dubious Test returned status 1 (wstat 256, 0x100) DIED.

I don't understand why this would complain of skipping two subtests, nor why it says that I planned 1 test but ran 1 extra. Is this what normally happens when tests are skipped?

    skip "Data::Dummy not installed", 2 if $@; # ^ ^ # MESSAGE, NUM_TESTS_TO_SKIP

    You are only skipping 1 test but you are telling Test::More you are skipping 2 but your plan was only to do 1 test.....

    skip "Data::Dummy not installed", 1 if $@; ^ ^

    Will work just fine.....I even tested it ;-) Test::Harness hates plan != number of tests reported. See my Autogenerate Test Scripts for a neat little widget that will re-number your tests and fix your plan as well as writing most of the Test code for you.
