NAME

       Test::Needs - Skip tests when modules not available

SYNOPSIS

         # need one module
         use Test::Needs 'Some::Module';

         # need multiple modules
         use Test::Needs 'Some::Module', 'Some::Other::Module';

         # need a given version of a module
         use Test::Needs {
           'Some::Module' => '1.005',
         };

         # check later
         use Test::Needs;
         test_needs 'Some::Module';

         # skips remainder of subtest
         use Test::More;
         use Test::Needs;
         subtest 'my subtest' => sub {
           test_needs 'Some::Module';
           ...
         };

         # check perl version
         use Test::Needs { perl => 5.020 };

DESCRIPTION

       Skip test scripts if modules are not available.  The requested modules will be loaded, and
       optionally have their versions checked.  If the module is missing, the test script will be
       skipped.  Modules that are found but fail to compile will exit with an error rather than
       skip.

       If used in a subtest, the remainder of the subtest will be skipped.

       Skipping will work even if some tests have already been run, or if a plan has been
       declared.

       Versions are checked via a "$module->VERSION($wanted_version)" call.  Versions must be
       provided in a format that will be accepted.  No extra processing is done on them.

       If "perl" is used as a module, the version is checked against the running perl version
       ($]).  The version can be specified as a number, dotted-decimal string, v-string, or
       version object.

       If the "RELEASE_TESTING" environment variable is set, the tests will fail rather than
       skip.  Subtests will be aborted, but the test script will continue running after that
       point.

EXPORTS

   test_needs
       Has the same interface as when using Test::Needs in a "use".

SEE ALSO

       Test::Requires
           A similar module, with some important differences.  Test::Requires will act as a "use"
           statement (despite its name), calling the import sub.  Under "RELEASE_TESTING", it
           will BAIL_OUT if a module fails to load rather than using a normal test fail.  It also
           doesn't distinguish between missing modules and broken modules.

       Test2::Require::Module
           Part of the Test2 ecosystem.  Only supports running as a "use" command to skip an
           entire plan.
