=head1 NAME

Test2::Tools::Expressive -- Expressive tools for Perl's Test2 framework

=head1 VERSION

Version 0.01_01

=cut

our $VERSION = '0.01_01';

use parent 'Exporter';

our @EXPORT_OK = qw(
    is_undef
);

our @EXPORT = @EXPORT_OK;

use Test2::API qw( context );

=head1 SYNOPSIS

    use Test2::Tools::Expressive;

    my $user = get_user_object( $bogus_id );
    is_undef( $user, 'Should not be able to find a user with a bogus ID' );

=head1 WHY TEST::EXPRESSIVE?

Test2::Tools::Expressive is designed to make your code more readable,
based on the idea that reading English is easier and less prone to
misinterpretation than reading Perl, and less prone to error by reducing
common cut & paste tasks.


=head1 EXPORTS

All functions in this module are exported by default.

=head1 SUBROUTINES

=head2 is_undef( $got [, $name ] )

Verifies that C<$got> is undefined.

You must pass at least one argument.  Otherwise, calling C
with no parameters would pass.

=cut

sub is_undef {
    my $nargs = scalar @_;

    my $got = shift;
    my $name = shift;

    my $ok;
    my $ctx = context();

    if ( $nargs == 0 ) {
        $ok = $ctx->ok( 0, $name );
        $ctx->diag( 'Must pass a value to is_undef' );
    }
    else {
        $ok = $ctx->ok( !defined $got, $name );
    }

    $ctx->release;

    return $ok;
}
