NAME

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

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

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.

Test2::Require::Perl

Part of the Test2 ecosystem. Only supports running as a "use" command to skip an entire plan. Checks perl versions.

Test::If

Acts as a "use" statement. Only supports running as a "use" command to skip an entire plan. Can skip based on subref results.
