README
This package provides factories for typical data structures
Installation
You can install the package via composer:
composer require ensi/laravel-test-factories --dev
Version Compatibility
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
BaseApiFactory
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
