Test::Kwalitee::Extra - Run Kwalitee tests including optional indicators, especially, prereq_matches_use


version v0.2.0


  # Simply use, with excluding indicators
  use Test::Kwalitee::Extra qw(!has_example !metayml_declares_perl_version);

  # Use with eval guard, with excluding class
  use Test::More;
  eval { require Test::Kwalitee::Extra; Test::Kwalitee::Extra->import(qw(!:optional)); };
  plan( skip_all => "Test::Kwalitee::Extra not installed: $@; skipping") if $@;

  # Typically, this test is limited to author test or release test
  BEGIN { # limited to release test
    unless ($ENV{RELEASE_TESTING}) { # or $ENV{AUTHOR_TESTING} for author test
      require Test::More;
      Test::More::plan(skip_all => 'these tests are for release candidate testing');
  use Test::More;
  eval { require Test::Kwalitee::Extra; Test::Kwalitee::Extra->import(qw(!:optional)); };
  plan( skip_all => "Test::Kwalitee::Extra not installed: $@; skipping") if $@;


CPANTS checks Kwalitee indicators, which is not quality but automatically-measurable indicators how good your distribution is. Module::CPANTS::Analyse calcluates Kwalitee but it is not directly applicable to your module test. CPAN has already had Test::Kwalitee for the test module of Kwalitee. It is, however, impossible to calculate prereq_matches_use indicator, because dependent module Module::CPANTS::Analyse itself cannot calculate prereq_matches_use indicator. It is marked as needs_db, but only limited information is needed to calculate the indicator. This module calculate prereq_matches_use to query needed information to MetaCPAN.

For available indicators, see "INDICATORS" section.


You can specify including or excluding an indicator or a tag like Exporter. Valid tags are core, optional and experimental. For indicators, see Module::CPANTS::Analyse.

Please NOTE that to specify tags are handled a bit differently from Exporter. First, specifying an indicator is always superior to specifying tags, even though specifying an indicator is prior to specifying tags.

For example,

  use Test::Kwalitee::Extra qw(!has_example :optional);

!has_example is in effect, that is has_example is excluded, even though has_example is an optional indicator.

Second, default excluded indicators mentioned in "INDICATORS" section are not included by specifying tags. For example, in the above example, :optional does not enable is_prereq. You can override it by explicitly specifying the indicator:

  use Test::Kwalitee::Extra qw(manifest_matches_dist);


Some tags have special meanings.


If specified, do not call Test::Builder::plan. You may need to specify it, if this test is embedded into other tests.

:minperlver <version>

prereq_matches_use indicator ignores core modules. What modules are in core, however, is different among perl versions. If minimum perl version is specified in META.yml or such a meta information, it is used as minimum perl version. Otherewise, $], the version of the current perl interpreter, is used.

If specified, this option overrides them.

:retry <count>

The number of retry to query to MetaCPAN. This is related with prereq_matches_use and build_prereq_matches_use indicators only.

Defaults to 5.


In Module::CPANTS::Analyse, prereq_matches_use requires CPANTS DB setup by Module::CPANTS::ProcessCPAN. is_prereq really requires information of prereq of other modules but prereq_matches_use only needs mappings between modules and dists. So, this module query the mappings to MetaCPAN by using MetaCPAN::API::Tiny.

Recently, Module::CPANTS::Analyse has been changed much. For actual available indicators, please consult Module::CPANTS::Kwalitee::* documentation. For default configuration, indicators are treated as follows:


No longer available for Module::CPANTS::Analyse 0.88 or 0.90+.


No longer available for Module::CPANTS::Analyse 0.90+.


No longer available for Module::CPANTS::Analyse 0.88 or 0.90+, moved to Module::CPANTS::SiteKwalitee.


No longer available for Module::CPANTS::Analyse 0.88 or 0.90+, moved to Module::CPANTS::SiteKwalitee but supported by this module.
