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.
