Since you mention simplifying the code, do you actually
need IPC::Open3 ? In your sample code, you're only
reading process output.
If you don't need IPC::Open3 complexity, you could just
use magic open to read output :
sub shell_run
{
print "YYYY";
my $pid = open( my $fh, qq{ @_ | } ) or die "open: $!";
print for <$fh>;
close $fh or die "close: ", $? || $!;
print "ZZZZ";
}
trap { shell_run( 'perl', '-E', '"print \'TEXT IN\'"' ) };
is( $trap->stdout, "YYYYTEXT INZZZZ");
done_testing();
--> ok 1
