=head1 NAME
Test2::Require::Threads - Skip a test file unless the system supports threading
=head1 DESCRIPTION
It is fairly common to write tests that need to use threads. Not all systems
support threads. This library does the hard work of checking if threading is
supported on the current system. If threading is not supported then this will
skip all tests and exit true.
=head1 SYNOPSIS
use Test2::Require::Threads;
... Code that uses threads ...
=head1 EXPLANATION
Checking if the current system supports threading is not simple, here is an
example of how to do it:
use Config;
sub CAN_THREAD {
# Threads are not reliable before 5.008001
return 0 unless $] >= 5.008001;
return 0 unless $Config{'useithreads'};
# Devel::Cover currently breaks with threads
return 0 if $INC{'Devel/Cover.pm'};
return 1;
}
Duplicating this non-trivial code in all tests that need to use threads is
error-prone. It is easy to forget bits, or get it wrong. On top of these checks you
also need to tell the harness that no tests should run and why.
