Modifying my module to use diag instead of print did the trick:

ackage Test::Utils::Dump;
use Term::ANSIColor qw(colored);
use Test::More;
use strict;

use Data::Dumper qw(Dumper);


# export the dump function
use Exporter qw(import);
our @EXPORT_OK = qw(d);
$Data::Dumper::Indent = 2;
$Data::Dumper::Terse = 1;

# dump the data passed in
sub d {
    my $data = shift;
    my $out = '';
    # print the data and the caller
    $caller_line = "Dump from: " . (caller(0))[1]
      . ' line: ' . (caller(0))[2];

    diag colored(['yellow'], $caller_line);
    diag colored(['blue'], Dumper($data));
    diag colored(['yellow'], $caller_line);
}
