Documentation

This package adds a method to the library Faker to fake domain object and value object contents.

Because of the recursive nature this is the easiest setup:

<?php
use Apie\Faker\ApieObjectFaker;
use Faker\Factory;

$faker = Factory::create();
$faker->addProvider(ApieObjectFaker::createWithDefaultFakers($faker));

// returns a random Gender enum value.
$faker->fakeClass(Gender::class);

class User implements EntityInterface
{
    // ...
    public function __construct(private Gender $gender, private FirstName $firstName, private LastName $lastName)
    {
    }
}
// creates a User with random constructor arguments.
$faker->fakeClass(User::class);

String value objects with regular expressions.

String value objects that have the trait IsStringWithRegexValueObject and implement HasRegexValueObjectInterface will be faked easily by using the regular expression to make a valid value object.

Adding custom support

You can create a class implementing ApieClassFaker to make your own fake methods. You can reuse the methods available in Faker itself.

<?php
use Apie\Faker\Interfaces\ApieClassFaker;
use Faker\Generator;
use ReflectionClass;

class SpecificClassFaker implements ApieClassFaker
{
    public function supports(ReflectionClass $class): bool
    {
        return $class->name === SpecificValueObject::class;
    }
    public function fakeFor(Generator $generator, ReflectionClass $class): SpecificValueObject
    {
        return new SpecificValueObject($generator->randomElement([1, 2, 3]));
    }
}

Adding a createRandom method in the object itself.

Instead of making many ApieClassFaker methods you can make a method on the value object that will result in a random value object.

<?php
use Apie\Core\Attributes\FakeMethod;
use Apie\Core\ValueObjects\Interfaces\ValueObjectInterface;

#[FakeMethod("createRandom")]
class SpecificClass implements ValueObjectInterface
{
    public static function createRandom(): self
    {
        return new self(rand(1, 3));
    }
}

You can also provide arguments to this method or the Faker generator itself:

<?php
use Apie\Core\Attributes\FakeMethod;
use Apie\Core\ValueObjects\Interfaces\ValueObjectInterface;
use Faker\Generator;

#[FakeMethod("createRandom")]
class SpecificClass implements ValueObjectInterface
{
    public static function createRandom(Generator $generator, int $maximum): self
    {
        return new self($generator->numberBetween(1, $maximum));
    }
}

In this case calling $faker->fakeClass(SpecificClass::class); will run SpecificClass::createRandom() with the faker and a random integer.
