Hello kuldeek, and welcome to the Monastery!

I’m not sure exactly what you want, but perhaps the select function is what you’re looking for:

#! perl
use strict;
use warnings;
use autodie;

my %test_hash = ( Foo => 1, Bar => 1, Baz => 1, Nix => 0 );

foreach my $test_run (keys %test_hash)
{
    if ($test_hash{$test_run} == 1)
    {
        my $test_execute  = $test_run;
        my $test_execute1 = $test_run     . '.pm';
        my $logfile       = $test_execute . '_log.txt';

        print "the logfile is $logfile\n";
        open(my $out, '>', $logfile);
        select  $out;
        require $test_execute1;
        $test_execute->$test_execute();
        close($out);
        select STDOUT;
    }
}

With suitable modules Foo.pm, Bar.pm, and Baz.pm, this code creates a log file for each module and redirects STDOUT to it from that module’s test sub. Output from print "the logfile is $logfile\n" is not redirected.

See how do i redirect STDOUT, STDIN, or STDERR to a FILE?.

Hope that helps,
