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.
