If possible I would like to use variable that is accessible bye ref_test2 without passing in as argument.
So you mean you want to share a variable between functions? The solution here is to use a lexical within a closure: 

{ # closure starts here
  my $shared_variable;
  sub ref_test1 { ... }
  sub ref_test2 { ... }
}
