How do you test code that uses method modifiers (before/after/around)?

Testing code that uses method modifiers such as before, after, and around in Perl can be done using modules like Test::More and Moose or MooseX::Method::Modifiers. We can write tests to ensure that our method modifiers are behaving as expected. Below is an example demonstrating how to test methods with modifiers in Perl.

# Sample Perl Code with Method Modifiers use Moose; use MooseX::Method::Modifiers; # A simple class with a method package MyClass { use Moose; sub foo { return "original foo"; } } # Adding modifiers with MooseX::Method::Modifiers around 'foo' => sub { my ($orig, $self) = @_; return "around: " . $self->$orig(); }; before 'foo' => sub { my $self = shift; return "before: " . $self->foo(); }; after 'foo' => sub { my $self = shift; return "after: " . $self->foo(); }; # Testing the method modifiers use Test::More; my $obj = MyClass->new(); is($obj->foo(), "after: before: around: original foo", 'foo returns expected value'); done_testing();
