NAME

6       Test2::Plugin::SRand - Control the random seed for more controlled test
7       environments.
8

DESCRIPTION

10       This module gives you control over the random seed used for your unit
11       tests. In some testing environments the random seed can play a major
12       role in results.
13
14       The default configuration for this module will seed srand with the
15       local date.  Using the date as the seed means that on any given day the
16       random seed will always be the same, this means behavior will not
17       change from run to run on a given day. However the seed is different on
18       different days allowing you to be sure the code still works with actual
19       randomness.
20
21       The seed is printed for you on failure, or when the harness is verbose.
22       You can use the "T2_RAND_SEED" environment variable to specify the
23       seed. You can also provide a specific seed as a load-time argument to
24       the plugin.

SYNOPSIS

27       Loading the plugin is easy, and the defaults are sane:
28
29           use Test2::Plugin::SRand;
30
31       Custom seed:
32
33           use Test2::Plugin::SRand 42;
34

NOTE ON LOAD ORDER

36       If you use this plugin you probably want to use it as the first, or
37       near-first plugin. "srand" is not called until the plugin is loaded, so
38       other plugins loaded first may already be making use of random numbers
39       before your seed takes effect.
