How do you test code that uses bless and basic OO?

In Perl, object-oriented programming (OO) is achieved using the `bless` function to associate a reference with a class. Testing such code requires understanding how to create objects, manipulate them, and ensure that methods function as expected.

Below is an example that illustrates the use of `bless` in a simple object-oriented Perl class and how to test it.

package Animal; sub new { my ($class, $name) = @_; my $self = { name => $name }; bless $self, $class; return $self; } sub speak { my ($self) = @_; return "Roar! My name is " . $self->{name}; } 1; # End of package

To test this code, you might create a simple script that uses the `Animal` class:

use Animal; my $lion = Animal->new("Leo"); print $lion->speak(); # Output: Roar! My name is Leo
