test::requires
Test::Requires(3) User Contributed Perl Documentation Test::Requires(3)NAME
Test::Requires - Checks to see if the module can be loaded
SYNOPSIS
# in your Makefile.PL
use inc::Module::Install;
test_requires 'Test::Requires';
# in your test
use Test::More tests => 10;
use Test::Requires {
'HTTP::MobileAttribute' => 0.01, # skip all if HTTP::MobileAttribute doesn't installed
};
isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile';
# or
use Test::More tests => 10;
use Test::Requires qw(
HTTP::MobileAttribute
);
isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile';
# or
use Test::More tests => 10;
use Test::Requires;
test_requires 'Some::Optional::Test::Required::Modules';
isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile';
DESCRIPTION
Test::Requires checks to see if the module can be loaded.
If this fails rather than failing tests this skips all tests.
Test::Requires can also be used to require a minimum version of Perl:
use Test::Requires "5.010"; # quoting is necessary!!
# or
use Test::Requires "v5.10";
