NAME

Test::UsedModules - Detects needless modules which are being used in your module

VERSION

This document describes Test::UsedModules version 0.03

SYNOPSIS

# check all of modules that are listed in MANIFEST
use Test::More;
use Test::UsedModules;
all_used_modules_ok();
done_testing;

# you can also specify individual file
use Test::More;
use Test::UsedModules;
used_modules_ok('/path/to/your/module_or_script');
done_testing;

DESCRIPTION

Test::UsedModules finds needless modules which are being used in your module to clean up the source code. Used modules (it means modules are used by 'use', 'require' or 'load (from Module::Load)' in target) will be checked by this module.

METHODS

  • all_used_modules_ok

    This is a test function which finds needless used modules from modules that are listed in MANIFEST file.

  • used_modules_ok

    This is a test function which finds needless used modules from specified source code. This function requires an argument which is the path to source file.

DEPENDENCIES

  • PPI (version 1.215 or later)

  • Test::Builder::Module (version 0.98 or later)

KNOWN PROBLEMS

  • Cannot detects rightly when target module applies monkey patch.

    e.g. HTTP::Message::PSGI

    It applies monkey patch to HTTP::Request and HTTP::Response.

  • Cannot detects when target module is used by `Module::Load::load` and module name is substituted in variable.

    e.g.

    use Module::Load;
my $module = 'Foo::Bar';
load $module;

    in this case, Test::UsedModules will not notify even if Foo::Bar has never been used.
