NAME

Test2::Require − Base class and documentation for skip−unless type test packages.

Test2::Require::* packages are packages you load to ensure your test file is skipped unless a specific requirement is met. Modules in this namespace may subclass Test2::Require if they wish, but it is not strictly necessary to do so.

HOW DO I WRITE A ’REQUIRE’ MODULE?

AS A SUBCLASS

package Test2::Require::Widget;
use strict;
use warnings;
use base 'Test2::Require';
sub HAVE_WIDGETS { ... };
sub skip {
my $class = shift;
my @import_args = @_;
if (HAVE_WIDGETS()) {
# We have widgets, do not skip
return undef;
}
else {
# No widgets, skip the test
return "Skipped because there are no widgets" unless HAVE_WIDGETS();
}
}
1;

A subclass of Test2::Require simply needs to implement a skip() method. This method will receive all import arguments. This method should return undef if the test should run, and should return a reason for skipping if the test should be skipped.

STAND-ALONE

If you do not wish to subclass Test2::Require then you should write an import() method:

package Test2::Require::Widget;
use strict;
use warnings;
use Test2::API qw/context/;
sub HAVE_WIDGETS { ... };
sub import {
my $class = shift;
# Have widgets, should run.
return if HAVE_WIDGETS();
# Use the context object to create the event
my $ctx = context();
$ctx−>plan(0, SKIP => "Skipped because there are no widgets");
$ctx−>release;
}
1;
