DESCRIPTION

This module also performs a numer of test on the distribution itself. It checks that your files match your SIGNATURE file if you have one. It checks that your distribution isn't missing certain 'core' description files. It checks to see you havent' missed out listing any pre-requisites in Makefile.PL.

It defines its own testing plan, so you usually don't use it in conjunction with other "Test::*" modules in the same file. It's recommended that you just create a one-line test script as shown in the SYNOPSIS above. However, there are options...

NOTE If you do not specify any options Test::Distribution will run all test types except signature testing which must always be explicitly switched on.

In the future I may change the default to run no tests at all as this sounds safer. Mail me if you disagree.

OPTIONS

"tests => NUMBER"

Specifies that in addition to the tests run by this module, your test script will run additional tests. In other words, this value influences the test plan. For example:

  use Test::Distribution tests => 1;
  use Test::More;
  is($foo, $bar, 'baz');
    

It is important that you don't specify a "tests" argument when using "Test::More" or other test modules as the plan is handled by "Test::Distribution".

DEPRECATED FEATURE. I plan to remove this in the future unless I'm contacted by someone that says they find this useful.

"only => STRING|LIST"

Specifies that only certain sets of tests are to be run. Possible values are those mentioned in TEST TYPES below. For example, if you only want to run the POD tests, you could say:

  use Test::Distribution only => 'pod';
    

To specify that you only want to run the POD tests and the "use" tests, and also that you are going to run two tests of your own, use:

  use Test::Distribution
    only  => [ qw/pod use/ ],
    tests => 2;
    

Note that when you specify the "versions" option, the "use" option is automatically added. This is because in order to get a module's $VERSION, it has to be loaded. In this case we might as well run a "use" test.

The value for "only" can be a string or a reference to a list of strings.

"not => STRING|LIST"

Specifies that certain types of tests should not be run. All tests not mentioned in this argument are run. For example, if you want to test everything except the POD, use:

  use Test::Distribution
    not => 'pod';
    

The value for "not" can be a string or a reference to a list of strings. Although it doesn't seem to make much sense, you can use both "only" and "not". In this case only the tests specified in "only", but not "not" are run (if this makes any sense).

"distversion"

If you test this to a true value, as well as testing that each module has a $VERSION defined, Test::Distribution will also ensure that the $VERSION matches that of the distribution.

"podcoveropts"

You can set this to be a hash reference of options to pass to Test::Pod::Coverage's pod_coverage_ok method (which in turn gets passed to Pod::Coverage.

TEST TYPES

"description"

Checks that the following files exist:

"prereq"

Checks whether all "use()"d modules that aren't in the perl core are also mentioned in Makefile.PL's "PREREQ_PM".

"pod"

Checks for POD errors in files

"podcover"

Checks for Pod Coverage

"sig"

If the distribution has a SIGNATURE file, checks the SIGNATURE matches the files.

"use"

This "use()"s the modules to make sure the load happens ok.

"versions"

Checks that all packages define $VERSION strings.

EXPOSED INTERNALS

"Test::Distribution::packages()"

This is a list of packages that have been found. That is, we assume that each file contains a package of the name indicated by the file's relative position. For example, a file in "blib/lib/Foo/Bar.pm" is expected to be available via "use Foo::Bar".

"Test::Distribution::files()"

This is a list of files that tests have been run on. The filenames are relative to the distribution's root directory, so they start with "blib/lib".

"Test::Distribution::num_tests()"

This is the number of tests that this module has run, based on your specifications.

INSTALLATION

  perl Build.PL
  ./Build
  ./Build test
  ./Build install

If you do not have Module::Build type:

  perl Makefile.PL

to fetch it. Or use CPAN or CPANPLUS and fetch it "manually".

DEPENDENCIES

 File::Basename
 File::Find::Rule
 File::Spec
 Test::More

This module has these optional dependencies:

 Module::CoreList
 Test::Pod
 Test::Pod::Coverage

If "Module::CoreList" is missing, the "prereq" tests are skipped.

If "Test::Pod" is missing, the "pod" tests are skipped.

TODO

•

Module::Build support [currently waiting for a fix on Test::Prereq ]

FEATURE IDEAS

"export" test type

This would mandate that there should be a test for each exported symbol of each module.

Let me know what you think of these ideas. Are they necessary? Unnecessary? Do you have feature requests of your own?
