NAME

Test::Needs - Skip tests when modules not available

SYNOPSIS

  use Test::Needs 'Some::Module';

  # check module version
  use Test::Needs {
    'Some::Module' => '1.005',
  };

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

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

  # 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 rest of the subtest will be skipped.

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.
