NAME

Test::Stochastic - checking probabilities of randomized methods

SYNOPSIS

            

              
              
use Test::Stochastic qw(stochastic_ok);
stochastic_ok sub { ...random sub...}, {a => 0.4, b => 0.6};
stochastic_ok  {a => 0.4, b => 0.6}, sub { ...random sub...};
Test::Stochastic::setup(times => 100, tolerence => 0.1);
            
          

DESCRIPTION

This module can be used to check the probability distribution of answers given by a method. The code fragments in the synopsis above check that the subroutine passed to stochastic_ok returns a with probability 0.4, and b with probability 0.6.

This module will work only if the return values are numbers or strings. Future versions will handle references as well.

EXPORT

None by default, stochastic_ok on request.
