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 pluggable 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 and condition
    coverage data should be mostly accurate too. 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 greater.  (Perl 5.7.0 is also unsupported.)
      The ability to compile XS extensions.
      Pod::Coverage if you want pod coverage.
      Template Toolkit 2 if you want HTML output.
