=head1 NAME

Perl::Critic::Policy::InputOutput::ProhibitInteractiveTest - Use prompt() instead of -t.

=head1 AFFILIATION

This Policy is part of the core L<Perl::Critic|Perl::Critic>
distribution.


=head1 DESCRIPTION

The C<-t> operator is fragile and complicated.  When you are testing
whether C<STDIN> is interactive, It's much more robust to use
well-tested CPAN modules like L<IO::Interactive|IO::Interactive>.


=head1 CONFIGURATION

This Policy is not configurable except for the standard options.
