Hi Monks of Monastery ! I did this following code to compare some screenshots between differents browsers. I use Selenium::Screenshot. But i find that it's too heavy. I use the condition "unless" which is not very handy i think, and it's the first time i use it. My code here : 
  unless ($screen{'firefox'}->compare($screen{'chrome'})) {
    my $diff_file = $screen{'firefox'}->difference($screen{'chrome'});
    print '#The images are not the same; see ' . $diff_file . ' for de
+tails'. "\n";
 
  `$diff_file`;


  unless ($screen{'internet explorer'}->compare($screen{'firefox'})) {
    my $diff_file = $screen{'internet explorer'}->difference($screen{'
+firefox'});
    print '#The images are not the same; see ' . $diff_file . ' for de
+tails'. "\n";
 
  `$diff_file`;

  unless ($screen{'chrome'}->compare($screen{'internet explorer'})) {
    my $diff_file = $screen{'chrome'}->difference($screen{'internet ex
+plorer'});
    print '#The images are not the same; see ' . $diff_file . ' for de
+tails'. "\n";
 
  `$diff_file`;

I have a newbie question also. I just would like to know how is it possible to simplify my code with "unless"?

Regards !
