How do you test code that uses translation tr///?

Testing Perl Code with tr///

In Perl, the `tr///` function is used for translating characters in a string. To effectively test code that utilizes `tr///`, you can write test cases that ensure the expected translations occur correctly. Below is an example demonstrating the usage of `tr///` in a Perl script.


        #!/usr/bin/perl
        use strict;
        use warnings;

        my $string = "hello world";
        $string =~ tr/a-z/A-Z/;  # Translating lowercase to uppercase
        print $string;            # Outputs: HELLO WORLD
