What are some code coverage tools for Perl?

Question

Are there any good (and preferably free) code coverage tools out there for Perl?

Answer 1

Yes, Devel::Cover is the way to go.

If you develop a module, and use Module::Build to manage the installation, you even have a testcover target:

 perl Build.PL
 ./Build testcover

That runs the whole test suite, and makes a combined coverage report in nice HTML, where you can browse through your modules and watch their coverage.
