Module creation: testing prerequisite

frazap has asked for the wisdom of the Perl Monks concerning the following question:

I'm writing a module that has the following PREREQ_PM

 PREREQ_PM    => {
                     'Test::More' => 1,
              'interface' => 0.03,
              'Try::Tiny' => 0.22,
              'DBI' => 1.631,
              'Carp' => 1.17,
              'Log::Log4perl' => 1.41,
             'Data::Dumper' => 2.154,
              'SQL::Abstract::More' => 1.27 
                    },
[download]

I'm would like to test that the intall process fetch and setup the missing module(s), so on my .../perl/site/lib directory I have renamed interface.pm to _interface.pm.

I have also added in the test (using Test::More)

require_ok('interface'); Now when I run dmake disttest that test failed.

I thought that running

perl Makefile.pl
dmake
[download]

would download and install the Scott Walter's interface module...

but no...

What am I missing ?

Thanks

If you want to install the prerequisites of a module distribution unpacked in the current directory, just run `cpanm --installdeps .` [download] This will run your `Makefile.PL`, extract the prerequisites, and then install the missing prerequisites. I think that `cpan` itself can also install just the prerequisites of a module, but I don't know the incantation off-hand.	[reply] [d/l] [select]

What am I missing ? realistic expectations You've confused a feature of cpan/cpanm/cpanp , installing missing/required prerequisites, with a feature of ExtUtils::MakeMaker/Makefile.PL See Module::AutoInstall and ExtUtils::AutoInstall	[reply]
