Term::ReadLine reads from the console, not from STDIN. That said, I'm surprised I can't find an option to use STDIO for circumstances such as this one.

I *think* you can do the following: 

my $term;
if ($ENV{TESTING}) {
   $term = Term::ReadLine->new('My Application', \*STDIN, \*STDOUT);
} else {
   $term = Term::ReadLine->new('My Application');
}

or even 

my $term;
if (-t STDIN) {
   $term = Term::ReadLine->new('My Application');
} else {
   $term = Term::ReadLine->new('My Application', \*STDIN, \*STDOUT);
}

The previous might simplify to: 

my $term = Term::ReadLine->new('My Application', \*STDIN, \*STDOUT);

If that doesn't work, the following should (if you only use readline): 

use IO::Handle;

{
   package IO::Handle;
   no warnings 'redefine';
   sub readline {
      my ($self) = @_;
      my $line = $self->getline();
      return unless defined $line;
      chomp($line);
      return $line;
   }
}

my $term;
if (-t STDIN) {
   $term = Term::ReadLine->new('My Application');
} else {
   $term = *STDIN;
}
