NAME Test::Distribution - perform tests on all modules of a distribution SYNOPSIS $ cat t/01distribution.t use Test::Distribution; $ make test ... DESCRIPTION When using this module in a test script, it goes through all the modules in your distribution, checks their POD, checks that they compile ok and checks that they all define the same $VERSION. It defines its own testing plan, so you usually don't use it in conjunction with other "Test::*" modules in the same file. It's recommended that you just create a one-line test script as shown in the SYNOPSIS above. However, there are options... OPTIONS On the line in which you "use()" this module, you can specify named arguments that influence the testing behavior. "tests => NUMBER" Specifies that in addition to the tests run by this module, your test script will run additional tests. In other words, this value influences the test plan. For example: use Test::Distribution tests => 1; use Test::More; is($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". "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). TEST TYPES Here is a description of the types of tests available. "pod" Checks for POD errors in files "use" This "use()"s the modules to make sure the load happens ok. "versions" Checks that all packages define $VERSION strings. "description" Checks that the following files exist: Changes MANIFEST README Makefile.PL "prereq" Checks whether all "use()"d modules that aren't in the perl core are also mentioned in Makefile.PL's "PREREQ_PM". TEST::DISTRIBUTION'S OWN PREREQUISITES "Test::Distribution" uses "File::Find::Rule" and "Test::Pod", amongst other modules. Each of these modules have their own rather long list of prerequisites. If you use the CPAN shell or a package manager to install modules, this is probably of no concern, but if you install modules manually, you might not care to install a lot of modules just to get "Test::Distribution" to run. Because of this, "Test::Distribution" checks whether you have the required modules installed and skips tests (per "Test::More" definition) as necessary if these modules are not found. If you don't have "Test::Pod", you can't run the "pod" tests. If you don't have "Module::CoreList", you can't run the "prereq" tests. But if you don't have "File::Find::Rule", all tests are skipped. EXPOSED INTERNALS There are a few subroutines to help you see what this module is doing. Note that these subroutines are neither exported nor exportable, so you have to call them fully qualified. "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. FEATURE IDEAS "manifest" test type This would check the MANIFEST's integrity. "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? BUGS If you find any bugs or oddities, please do inform the maintainer.
