=head1 NAME
Test::SharedFork - fork test
=head1 SYNOPSIS
use Test::More tests => 200;
use Test::SharedFork;
my $pid = fork();
if ($pid == 0) {
# child
ok 1, "child $_" for 1..100;
} elsif ($pid) {
# parent
ok 1, "parent $_" for 1..100;
waitpid($pid, 0);
} else {
die $!;
}
=head1 DESCRIPTION
Test::SharedFork is utility module for Test::Builder.
This module makes L<fork(2)> safety in your test case.
This module merges test count with parent process & child process.
=head1 LIMITATIONS
This version of the Test::SharedFork does not support ithreads, because L<threads::shared> conflicts with L<Storable>.
