Test::Harness is an utility script invoked by Test::Simple, Test::More and several based on Test::Builder. It is also part of the perl-modules installation. This module is packaged to satisfy the build-dependency of several other Perl modules over a newer version than the one perl-modules provides - Please refer to bug #383517 for the rationale on separately packaging it.
