Hi Monks ! I am on a learning curve with Perl. I am trying to compare Screenshot between two different browsers for a same image ,in some Test. All is ok. I'am using Selenium::Screenshot and Test::Class modules. But when i would like to compare my screenshots outside of a loop, i have some issues. Here code i did:

sub Login_test : Tests {
  my $self = shift;


  foreach my $browser (@{$self->{browsers}}) {
    
    diag ("#browser $browser");
    my $driver = Test::Selenium::Remote::Driver->new( browser_name => 
+$browser);

    $driver->get_ok("$url","Get url ok");
    $driver->pause(2000);
    $driver->set_window_size(600, 600); 
    $driver->pause(2000);
    my $white = Selenium::Screenshot->new(
                   png => $driver->screenshot,
                   exclude => [{
                     size     => { width => 100, height => 100 }, #  s
+ize      => $elem->get_size,
                     location => { x => 5, y => 5 }, #location  => $el
+em->get_element_location,
      }]
    );
    
    $driver->find_element('login','id')->send_keys("ok");
    $driver->find_element('password','id')->send_keys("okok");
    $elem = $driver->find_element('login','id');
    $driver->mouse_move_to_location(element => $elem);
    $driver->click_ok('Click on Button submit ok');
    $driver->pause(5000);


    $white->save( file => "snapScreenshot-$browser" );
    #$driver->execute_script('document.getElementsByTagName("body")[0]
+.style.backgroundColor = "red"');
    my $blue = Selenium::Screenshot->new(png => $driver->screenshot);
    $blue->save( file => "snapScreenshot1-$browser" );

    $elem = $driver->find_element('//a[@href="/logout"]');
    $driver->mouse_move_to_location(element => $elem);
    $driver->click_ok('Logout ok');
    $driver->pause(3000);

    $driver->quit();
  }


  unless ($white{browser_name => $browser[0]}->compare($blue{browser_n
+ame => $browser[1]})) {
    $diff_file = $white->difference($blue);
    print '#The images differ; see ' . $diff_file . ' for details'. "\
+n";
  

  my $open_cmd;
  if ($^O eq 'darwin') {
      $open_cmd = 'open'
  }
  elsif ($^O eq 'MSWin32') {
      $open_cmd = '';
  }
  else {
      $open_cmd = 'display';
  }
  `$open_cmd $diff_file`;
  }
}

And here my output in Shell :

Global symbol "%white" requires explicit package name at MyTest.pm lin
+e 33.
Global symbol "@browser" requires explicit package name at MyTest.pm l
+ine 33.
Global symbol "%blue" requires explicit package name at MyTest.pm line
+ 33.
Global symbol "@browser" requires explicit package name at MyTest.pm l
+ine 33.
Global symbol "$diff_file" requires explicit package name at MyTest.pm
+ line 34.
Global symbol "$blue" requires explicit package name at MyTest.pm line
+ 34.
Global symbol "$diff_file" requires explicit package name at MyTest.pm
+ line 35.
Global symbol "$diff_file" requires explicit package name at MyTest.pm
+ line 38.
