NAME

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

DESCRIPTION

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();
    }
}

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;
