In some testing environments the random seed can play a major role in results. .PP 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. .PP The seed is printed for you on failure, or when the harness is verbose. You can use the \f(CW\*(C`T2_RAND_SEED\*(C'\fR environment variable to specify the seed. You can also provide a specific seed as a load-time argument to the plugin. .SH "SYNOPSIS" .IX Header "SYNOPSIS" Loading the plugin is easy, and the defaults are sane: .PP .Vb 1 \& use Test2::Plugin::SRand; .Ve .PP Custom seed: .PP .Vb 1 \& use Test2::Plugin::SRand 42; .Ve .SH "NOTE ON LOAD ORDER" .IX Header "NOTE ON LOAD ORDER" If you use this plugin you probably want to use it as the first, or near-first plugin. \f(CW\*(C`srand\*(C'\fR 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. .SH "SOURCE" .IX Header "SOURCE" The source code repository for Test2\-Suite can be found at \&\fIhttps://github.com/Test\-More/Test2\-Suite/\fR. .SH "MAINTAINERS" .IX Header "MAINTAINERS" .IP "Chad Granum " 4 .IX Item "Chad Granum " .SH "AUTHORS" .IX Header "AUTHORS" .PD 0 .IP "Chad Granum " 4 .IX Item "Chad Granum " .PD .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018 Chad Granum . .PP This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself. .PP See \fIhttp://dev.perl.org/licenses/\fR
