Basic usage

Let's create a factory and extend abstract Factory. All you need is to define definition and make methods.

use Ensi\LaravelTestFactories\Factory;

class CustomerFactory extends Factory
{
    public ?int $id = null;
    public ?FileFactory $avatarFactory = null;
    public ?array $addressFactories = null;

    protected function definition(): array
    {
        return [
            'id' => $this->whenNotNull($this->id, $this->id),
            'user_id' => $this->faker->randomNumber(),
            'is_active' => $this->faker->boolean(),
            'date_start' => $this->faker->dateTime(),
            'avatar' => $this->avatarFactory?->make(),
            'addresses' => $this->executeNested($this->addressFactories, new FactoryMissingValue()),
        ];
    }

    public function make(array $extra = []): CustomerDTO
    {
        static::$index += 1;

        return new CustomerDTO($this->mergeDefinitionWithExtra($extra));
    }

    public function withId(?int $id = null): self
    {
        return $this->immutableSet('id', $id ?? $this->faker->randomNumber());
    }

    public function withAvatar(FileFactory $factory = null): self
    {
        return $this->immutableSet('avatarFactory', $factory ?? FileFactory::new());
    }

    public function includesAddresses(?array $factories = null): self
    {
        return $this->immutableSet('addressFactories', $factories ?? [CustomerAddressFactory::new()]);
    }

    public function active(): self
    {
        return $this->state([
            'is_active' => true,
            'date_start' => $this->faker->dateTimeBetween('-30 years', 'now'),
        ]);
    }
}

// Now we can use Factory like that
$customerData1 = CustomerFactory::new()->make();
$customerData2 = CustomerFactory::new()->active()->make();
$customerData3 = CustomerFactory::new()->withId()->withAvatar(FileFactory::new()->someCustomMethod())->make();

As you can see the package uses fakerphp/faker to generate test data.

You can override any fields in make method:

$customerData1 = CustomerFactory::new()->make(['user_id' => 2]);

If you target is an array, then you can use a helper method makeArray:

    public function make(array $extra = []): array
    {
        return $this->makeArray($extra);
    }

It's recommended to use $this->immutableSet in state change methods to make sure previously created factories are not affected.

Making several objects

$customerDataObjects = CustomerFactory::new()->makeSeveral(3); // returns Illuminate\Support\Collection with 3 elements

Additional Faker methods

$this->faker->randomList(fn() => $this->faker->numerify(), 0, 10) // => ['123', ..., '456']
$this->faker->nullable() // equivalent for $this->faker->optional(), but work with boolean parameter or global static setting
$this->faker->exactly($value) // return $value. Example: $this->faker->nullable()->exactly(AnotherFactory::new()->make())
$this->faker->carbon() // return CarbonInterface
$this->faker->dateMore()
$this->faker->modelId() // return unsigned bit integer value

Additional traits

WithSetPkTrait

If your model has unique index consisting of multiple fields, WithSetPkTrait trait should be used to ensure generated values for these fields are unique.

In order for trait to work, you have to define methods getPkFields, setPk and generatePk and include getPk call in definition. Following is the example of a factory ('client_id' and 'location_id' are fields forming unique index):

    class ClientAmountFactory extends BaseModelFactory
{
    use WithSetPkTrait;

    protected $model = ClientAmount::class;

    public function definition(): array
    {
        return array_merge($this->getPk(), [
            'amount' => $this->faker->numberBetween(1, 1_000_000),
        ]);
    }

    public function getPkFields(): array
    {
        return ['client_id', 'location_id'];
    }

    public function setPk(?int $clientId = null, ?string $locationId = null): self // Use in tests to define values
    {
        return $this->state(function () use ($clientId, $locationId) {
            return $this->generatePk($clientId, $locationId);
        });
    }

    protected function generatePk(?int $clientId = null, ?string $locationId = null): array
    {
        $clientIdFormat = $clientId ?: '\d{10}';
        $locationIdFormat = $locationId ?: '[0-9]{1,10}';

        $unique = $this->faker->unique()->regexify("/^{$clientIdFormat}_{$locationIdFormat}");

        $uniqueArr = explode('_', $unique);

        return [
            'client_id' => (int)$uniqueArr[0],
            'location_id' => $uniqueArr[1],
        ];
    }
}

Important note - fields must be declared in the same order in getPkFields and setPk methods.

Parent classes

This class is the base for your factories of various Api responses/requests.

It also provides the generateResponseSearch method, which allows you to generate a response in the :search format of the endpoint described here

BaseModelFactory

This class is the base class for your Eloquent model factories

Factories

• PaginationFactory - factory for generating response pieces and pagination requests
• PromiseFactory - factory for generating GuzzleHttp\Promise\PromiseInterface
