=head1 METHODS

version of modules a specific set of features requires for this version of
-DBIx::Class. See the L</SYNOPSIS> for a real-world example.

+See the L</SYNOPSIS> for a real-world example.
+
+When handling C<test_*> groups this method behaves B<differently> from
+L</modreq_list_for> below (and is the only such inconsistency among the
+C<req_*> methods). If a particular group declares as requirements some
+C<environment variables> and these requirements are not satisfied (the envvars
+are unset) - then the C<module requirements> of this group are not included in
+the returned list.

+C<environment variable requirements> - returns just the list of required

=head2 req_missing_for
