=head1 NAME

RT::Test - RT Testing

=head1 NOTES

=head2 COVERAGE

To run the rt test suite with coverage support, install L<Devel::Cover> and run:

    make test RT_DBA_USER=.. RT_DBA_PASSWORD=.. HARNESS_PERL_SWITCHES=-MDevel::Cover
    cover -ignore_re '^var/mason_data/' -ignore_re '^t/'

The coverage tests have DevelMode turned off, and have
C<named_component_subs> enabled for L<HTML::Mason> to avoid an optimizer
problem in Perl that hides the top-level optree from L<Devel::Cover>.

Takes a path relative to the location of the test file that is being
