NAME
Test2::Plugin::SRand - Control the random seed for more controlled test environments.
DESCRIPTION
This module gives you control over the random seed used for your unit tests. In some
testing environments the random seed can play a major role in results.
The default configuration for this module will seed srand with the local date. Using the
date as the seed means that on any given day the random seed will always be the same, this
means behavior will not change from run to run on a given day. However the seed is
different on different days allowing you to be sure the code still works with actual
randomness.
The seed is printed for you on failure, or when the harness is verbose. You can use the
"T2_RAND_SEED" environment variable to specify the seed. You can also provide a specific
seed as a load-time argument to the plugin.
SYNOPSIS
Loading the plugin is easy, and the defaults are sane:
use Test2::Plugin::SRand;
Custom seed:
use Test2::Plugin::SRand seed => 42;
NOTE ON LOAD ORDER
If you use this plugin you probably want to use it as the first, or near-first plugin.
"srand" is not called until the plugin is loaded, so other plugins loaded first may
already be making use of random numbers before your seed takes effect.
