NAME

Test::RandomCheck::Generator - Tools to build a generator of random values

SYNOPSIS

use Test::RandomCheck::Generator;

my $data_generator = array_ref(
    hash_ref(
        string() => array_ref(elements qw(True False))
    ), 5, 10
);
# This generator yields values like following:
# {
#     'YLkOEF' => ['True'],
#     'TwpMygm' => ['False', 'False', 'False', 'True', 'False'],
# }

DESCRIPTION

Test::RandomCheck::Generator is a combinator to build random value generators used by Test::RandomCheck.

COMBINATORS

<const 1, 2, 3;>

A generator which always returns specified values.

<range 1, 6;>

A generator which returns integer from min to max randomly.

<elements qw(true false);>

A generator which returns an element randomly.

<list $gen, 3, 10;>

A generator which returns a list of values by using specified $gen. The generated list will have length from min(e.g. 3) to max(e.g. 10).

<integer;>

<char;>

<string 8, 12;>

A generator which generates values of primitive types.

<concat $gen1, $gen2, $gen3;>

A generator which generates a list of values. The generated list has fixed length which is the # of generators.

<hash_ref $key_gen, $val_gen, 3, 5;>

A generator which returns an hash-ref. Keys are produced by $key_gen and values are produced by $val_gen; $key_gen should return one string value. On the other hand, $value_gen should return just one value, but the value doesn't have to be string. Any types of values are O.K.

<array_ref $gen, 3, 5;>

A generator which returns an array-ref of values by using specified $gen. The generated array-ref will have length from min(e.g. 3) to max(e.g. 5).
