6.12. My own test functions

After writing lots of tests, you'll start to re-factor your code and create functions for specific parts of the test:

You will have some code like this:

use Test::More tests => 2;
is(my_test(2, '+', 3), 5);
is(my_test(4, '+', 4), 10);


sub my_test {
   my ($x, $op, $z) = @_;

   # do stuff

   return $result;
}
