How to suppress "warning" using Selenium::Remote::Driver?

no warnings;
use Selenium::Remote::Driver;
 
my $driver = Selenium::Remote::Driver->new;
$driver->get('https://www.crawler-test.com/');
$driver->find_element_by_xpath('//a[.="text not found"]');

How can I get the above code not to print this warning:

Error while executing command: no such element: Unable to locate element: //a[.="text not found"]

According to the docs, the function issues a "warning" if there is no element found, but having no warnings; in the script does not suppress it.

How can I suppress this "warning"?

Use find_element instead of find_element_by_xpath. The former throws an exception instead of issuing a warning. You can catch these exceptions using the following wrappers:

sub nf_find_element {
   my $node;
   if (!eval {
      $node = $web_driver->find_element(@_);
      return 1;  # No exception.
   }) {
      return undef if $@ =~ /Unable to locate element|An element could not be located on the page using the given search parameters/;
      die($@);
   }

   return $node;
}


sub nf_find_elements {
   my $nodes;
   if (!eval {
      $nodes = $web_driver->find_elements(@_);
      return 1;  # No exception.
   }) {
      return undef if $@ =~ /Unable to locate element|An element could not be located on the page using the given search parameters/;
      die($@);
   }

   return wantarray ? @$nodes : $nodes;
}


sub nf_find_child_element {
   my $node;
   if (!eval {
      $node = $web_driver->find_child_element(@_);
      return 1;  # No exception.
   }) {
      return undef if $@ =~ /Unable to locate element|An element could not be located on the page using the given search parameters/;
      die($@);
   }

   return $node;
}


sub nf_find_child_elements {
   my $nodes;
   if (!eval {
      $nodes = $web_driver->find_child_elements(@_);
      return 1;  # No exception.
   }) {
      return undef if $@ =~ /Unable to locate element|An element could not be located on the page using the given search parameters/;
      die($@);
   }

   return wantarray ? @$nodes : $nodes;
}

nf stands for "non-fatal".

Written for Selenium::Chrome, but should work with Selenium::Remote::Driver as well.
