# 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();
        }
    }

    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;
