=head1 NAME
Test2::Tools::Defer - Write tests that get executed at a later time
=head1 DESCRIPTION
Sometimes you need to test things BEFORE loading the necessary functions. This
module lets you do that. You can write tests, and then have them run later,
after C<Test2> is loaded. You tell it what test function to run, and what
arguments to give it. The function name and arguments will be stored to be
executed later. When ready, run C<do_def()> to kick them off once the functions
are defined.
=head1 SYNOPSIS
use strict;
use warnings;
use Test2::Tools::Defer;
BEGIN {
def ok => (1, 'pass');
def is => ('foo', 'foo', 'runs is');
...
}
use Test2::Tools::Basic;
do_def(); # Run the tests
# Declare some more tests to run later:
def ok => (1, "another pass");
...
do_def(); # run the new tests
done_testing;
=head1 EXPORTS
=over 4
=item def function => @args;
This will store the function name, and the arguments to be run later. Note that
each package has a separate store of tests to run.
=item do_def()
This will run all the stored tests. It will also reset the list to be empty so
you can add more tests to run even later.
