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. =head1 SEE ALSO =over 4 =item L Skip the test file if the system does not support forking. =item L Test2::Require::Threads uses L under the hood. =back =head1 SOURCE The source code repository for Test2-Suite can be found at F. =head1 MAINTAINERS =over 4 =item Chad Granum Eexodist@cpan.orgE =back =head1 AUTHORS =over 4 =item Chad Granum Eexodist@cpan.orgE =back =head1 COPYRIGHT Copyright 2018 Chad Granum Eexodist@cpan.orgE.
