Seriously, try using code tags when you post code, it makes everyone's life easier.

Now to address your question...

Code:

if (my $string =~ /\/\*temperature value test\*\//)

Examine that line for a moment... what does the =~ operator do? and how could $string match anything at that point?

Take a look at the following

Code:

~/tmp$ cat code.c 
#include code.h

//first test
if (test_passes()){
...
//second test
if (this_test_passes()){
..
//third test
if (this_test_passes()){

~/tmp$ cat test.pl
#!/usr/bin/perl

use strict;

my %test_description = ('first test'=>": This is the first test we undertake\n",
                        'second test'=>": This is the second test we undertake\n",
                        'third test'=>": This is the third test we undertake\n",
                       );
open (my $code , "<", 'code.c');
my $test_finder="(" . join("|", keys %test_description).")" ;
while(<$code>){
    if (/$test_finder/){
        chomp;
        $_.=$test_description{$1};
    }
    print $_
}
    
~/tmp$ ./test.pl
#include code.h

//first test: This is the first test we undertake
if (test_passes()){
...
//second test: This is the second test we undertake
if (this_test_passes()){
..
//third test: This is the third test we undertake
if (this_test_passes()){

Is that close to what you wish to do?
