DESCRIPTION

16       This module gives you control over the random seed used for your unit
17       tests. In some testing environments the random seed can play a major
18       role in results.
19
20       The default configuration for this module will seed srand with the
21       local date.  Using the date as the seed means that on any given day the
22       random seed will always be the same, this means behavior will not
23       change from run to run on a given day. However the seed is different on
24       different days allowing you to be sure the code still works with actual
25       randomness.
26
27       The seed is printed for you on failure, or when the harness is verbose.
28       You can use the "TS_RAND_SEED" environment variable to specify the
29       seed. You can also provide a specific seed as a load-time argument to
30       the plugin.
31

SYNOPSIS

33       Loading the plugin is easy, and the defaults are sane:
34
35           use Test::Stream 'SRand';
36
37       Custom seed:
38
39           use Test::Stream SRand => ['42'];
40

NOTE ON LOAD ORDER

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