NAME
Test2::Require::Threads - Skip a test file unless the system supports threading
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.
SYNOPSIS
use Test2::Require::Threads;
... Code that uses threads ...
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.
SEE ALSO
Test2::Require::CanFork

Test2
Test2::Require::Threads uses Test2 under the hood.
