Test::Needs(3pm)

Test::Needs3pm

Skip tests when modules not available

Usage

  # 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 };

Overview

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.
