DESCRIPTION

16       It is fairly common to write tests that need to use threads. Not all
17       systems support threads. This library does the hard work of checking if
18       threading is supported on the current system. If threading is not
19       supported then this will skip all tests and exit true.

SYNOPSIS

22           use Test::Stream::Plugin::CanThread;
23
24           ... Code that uses threads ...
25

EXPLANATION

27       Checking if the current system supports threading is not simple, here
28       is an example of how to do it:
29
30           use Config;
31
32           sub CAN_THREAD {
33               # Threads are not reliable before 5.008001
34               return 0 unless $] >= 5.008001;
35               return 0 unless $Config{'useithreads'};
36
37               # Devel::Cover currently breaks with threads
38               return 0 if $INC{'Devel/Cover.pm'};
39               return 1;
40           }
41
42       Duplicating this non-trivial code in all tests that need to use threads
43       is dumb. It is easy to forget bits, or get it wrong. On top of these
44       checks you also need to tell the harness that no tests should run and
45       why.
