Test::HasVersion - Check Perl modules have version numbers
Test::HasVersion lets you check a Perl module has a version
number in a Test::Simple fashion.
use Test::HasVersion tests => 1;
pm_version_ok("M.pm", "Valid version");
Module authors can include the following in a t/has_version.t
file and let Test::HasVersion find and check all
installable PM files in a distribution.
eval "use Test::HasVersion";
plan skip_all =>
Test::HasVersion required for testing for version numbers if $@;
Do you wanna check that every one of your Perl modules in
a distribution has a version number? You wanna make sure
you dont forget the brand new modules you just added?
Well, thats the module you have been looking for.
Do you wanna check someone elses distribution
to make sure the author have not committed the sin of
leaving Perl modules without a version that can be used
to tell if you have this or that feature? Test::HasVersion
is also for you, nasty little fellow.
Theres a script test_version which is installed with
this distribution. You may invoke it from within the
root directory of a distribution you just unpacked,
and it will check every .pm file in the directory
and under lib/ (if any).
You may also provide directories and files as arguments.
$ test_version *.pm lib/ inc/
$ test_version .
(Be warned that many Perl modules in a t/ directory
do not receive versions because they are not used
outside the distribution.)
Ok. Thats not a very useful module by now.
But it will be. Wait for the upcoming releases.
$v = _pm_version($pm);
Parses a PM file and return what it thinks is $VERSION
in this file. (Actually implemented with
use ExtUtils::MakeMaker; MM->parse_version($file).)
$pm is the filename (eg., lib/Data/Dumper.pm).
pm_version_ok(M.pm, Has valid version);
Checks to see if the given file has a valid
version. Actually a valid version number is
defined and not equal to undef (the string)
which is return by _pm_version if a version
cannot be determined.
Checks every given file and .pm files found
under given directories to see if they provide
valid version numbers. If no argument is given,
it defaults to check every file *.pm in
the current directory and recurses under the
lib/ directory (if it exists).
If no test plan was setted, Test::HasVersion will set one
after computing the number of files to be tested. Otherwise,
the plan is left untouched.
@pm_files = _list_pm_files(@dirs);
Returns all PM files under the given directories.
@files = all_pm_files()
@files = all_pm_files(@files_and_dirs);
Implements finding the Perl modules according to the
semantics of the previous function all_pm_version_ok.
Other usage patterns besides the ones given in the synopsis.
use Test::More tests => $num_tests;
Obviously, you cant plan twice.
plan tests => $num_tests;
plan comes from Test::More.
no_plan is ok either.
