Test::Kwalitee - Test the Kwalitee of a distribution before you release it
In a separate test file:
plan skip_all => 'these tests are for release candidate testing'
use Test::Kwalitee 'kwalitee_ok';
Kwalitee is an automatically-measurable gauge of how good your software is. That's very different from quality, which a computer really can't measure in a general sense. (If you can, you've solved a hard problem in computer science.)
In the world of the CPAN, the CPANTS project (CPAN Testing Service; also a funny acronym on its own) measures Kwalitee with several metrics. If you plan to release a distribution to the CPAN -- or even within your own organization -- testing its Kwalitee before creating a release can help you improve your quality as well.
Test::Kwalitee and a short test file will do this for you automatically.
Create a test file as shown in the synopsis. Run it. It will run all of the potential Kwalitee tests on the current distribution, if possible. If any fail, it will report those as regular diagnostics.
If you ship this test, it will not run for anyone else, because of the RELEASE_TESTING guard. (You can omit this guard if you move the test to xt/release/, which is not run automatically by other users.)
With no arguments, runs all standard metrics.
To run only a handful of tests, pass their name(s) to the kwalitee_ok function:
kwalitee_ok(qw( use_strict has_tests ));
To disable a test, pass its name with a leading minus (-):
kwalitee_ok(qw( -use_strict has_readme ));
Previous versions of this module ran tests directly via the import sub, like so:
# and that's it!
...but this is problematic if you need to perform some setup first, as you would need to do that in a BEGIN block, or manually call import. This is messy!
However, this calling path is still available, e.g.:
use Test::Kwalitee tests => [ qw( use_strict has_tests ) ];
The list of each available metric currently available on your system can be obtained with the kwalitee-metrics command (with descriptions, if you pass --verbose or -v, but as of Module::CPANTS::Analyse 0.97_03, the tests include:
Does the main module have a =head1 NAME section with a short description of the distribution?
Does the distribution have a build tool file?
Does the distribution have a changelog?
Is there a LICENSE section in documentation, and/or a LICENSE file present?
Is there license information in any of the source files?
Does the distribution have a MANIFEST?
Does the distribution have a META.yml file?
Does the distribution have a README file?
Does the distribution have tests?
Do the MANIFEST and distribution contents match?
Does META.json conform to the recognised META.json specification? (For specs see CPAN::Meta::Spec)
Can the META.json be parsed?
Does META.yml conform to any recognised META.yml specification? (For specs see http://module-build.sourceforge.net/META-spec-current.html)
Can the META.yml be parsed?
Is the distribution using an old version of Module::Install? Versions of Module::Install prior to 0.89 do not detect correctly that CPAN/CPANPLUS shell is used.
Does the distribution use an obsolete version of Module::Install? Versions of Module::Install prior to 0.61 might not work on some systems at all. Additionally if the Makefile.PL uses the auto_install() feature, you need at least version 0.64. Also, 1.04 is known to be broken.
Does the distribution have no symlinks?
Does the distribution files all use strict?
