How do you test code that uses carton for dependency management?

# Example of testing Perl code with Carton
# Step 1: Create a Carton environment
carton init

# Step 2: Add your Perl dependencies to the cpanfile
echo 'requires "Moo";' >> cpanfile

# Step 3: Install dependencies
carton install

# Step 4: Write your Perl script (example.pl)
cat <> example.pl
use Moo;

# Example module
package MyApp;
use Moo;

sub greet {
    return "Hello, World!";
}

1; # End of module
EOT

# Step 5: Write tests for your script (example.t)
cat <> example.t
use Test::More;
use lib '.';
use MyApp;

my $app = MyApp->new();
is($app->greet(), 'Hello, World!', 'Greet method returns expected value.');

done_testing();

# Step 6: Run your tests using Carton
carton exec perl example.t
