NAME Devel::Cover - Code coverage metrics for Perl DESCRIPTION This module provides code coverage metrics for Perl. If you can't guess by the version number this is an alpha release. Code coverage data are collected using a plugable runops function which counts how many times each op is executed. These data are then mapped back to reality using the B compiler modules. There is also a statement profiling facility which needs a better backend to be really useful. The cover program can be used to generate coverage reports. Statement, branch, condition, pod and time coverage information is reported. Statement coverage data should be reasonable, although there may be some statements which are not reported. Branch coverage data should be mostly accurate too. Condition coverage data are only available for && and || ops. These data should be mostly accurate, although not always what one might initially expect. Pod coverage comes from Pod::Coverage. Coverage data for path coverage are not yet collected. The gcov2perl program can be used to convert gcov files to Devel::Cover databases. You may find that the results don't match your expectations. I would imagine that at least one of them is wrong. THe most appropriate mailing list on which to discuss this module would be perl-qa. Discussion has migrated there from perl-qa-metrics which is now defunct. http://lists.perl.org/showlist.cgi?name=perl-qa Requirements: Perl 5.6.1 or 5.7.1. The ability to compile XS extensions. Pod::Coverage if you want pod coverage. Template Toolkit 2 if you want HTML output.
