NAME

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

AFFILIATION

Top

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

Top

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

CONFIGURATION

Top

This Policy is not configurable except for the standard options.
