Congrats to: - DateTime::Format::Bork and - DateTime::Format::HTTP Both have 100% coverage! Now I'm going through my modules and expanding on the tests - at least for the important modules like DT::F::Strptime and DT::F::Duration (and DT::E::Easter). I don't think I'll do too much extra testing on DT::F::Baby unless I have some absolutely-nothing-to-do time! Cheers!

These are coverage reports for CPAN modules' test suites. The columns
tell you what percent of certain things in a distro are being covered by
the tets. Pod coverage refers to documentation of public
methods/functions.
And yes, it's worth worrying about. Low coverage means your code is more
likely to have bugs.
If you use the latest Module::Build, you can generate coverage reports
very easily by running './Build testcover'.
Keep in mind that 100% coverage is often impossible. For example,
DateTime.pm includes this bit of code:
if ( $] >= 5.006 )
{
require XSLoader;
XSLoader::load( 'DateTime', $DateTime::VERSION );
}
else
{
require DynaLoader;
@DateTime::ISA = 'DynaLoader';
DateTime->bootstrap( $DateTime::VERSION );
}
To get this covered in a single testing run would be really difficult.
OTOH, looking through the coverage results, there are plenty of things
being missed by the DateTime.pm tests that could be covered.

It measures how much of your code is executed by the test suite. If a line of code (or subroutine) doesn't get executed when the test suite runs, then it can't have been tested, right? > What is it? and more importantly, what do the > columns mean? Is this something the we (the developers) > need to worry about? Depends on what you mean by "worry". There is a project called Phalanx that exists to improve the test suites of key Perl modules. See http://qa.perl.org/phalanx/ for details. Some of the Date::* modules are in our sights to be improved. xoa -- Andy Lester => [EMAIL PROTECTED] => www.petdance.com => AIM:petdance
