Fake entities generator

This package will help you generate fake entities and persist them to your ORM.

$factory = new \Butschster\EntityFaker\Factory(

Create and persist an entity

$user = $factory->of(User::class)->create();

//class User {
//  private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//  private string $username = "zetta86";
//  private string $email = "tsteuber@hotmail.com";
//}

Create and persist multiply entities

$users = $factory->of(User::class)->times(10)->create();

//[
//    class User {
//      private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//      private string $username = "zetta86";
//      private string $email = "tsteuber@hotmail.com";
//    },
//    ...
//]

Create and persist an entity with predefined attributes

$user = $factory->of(User::class)->create([
    'email' => 'admin@site.com'
]);

//class User {
//  private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//  private string $username = "zetta86";
//  private string $email = "admin@site.com";
//}

Create an entity

$user = $factory->of(User::class)->make();

//class User {
//  private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//  private string $username = "zetta86";
//  private string $email = "tsteuber@hotmail.com";
//}

Create multiply entities

$users = $factory->of(User::class)->times(10)->make();

//[
//    class User {
//      private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//      private string $username = "zetta86";
//      private string $email = "tsteuber@hotmail.com";
//    },
//    ...
//]

Create an entity with predefined attributes

$user = $factory->of(User::class)->make([
    'email' => 'admin@site.com'
]);

//class User {
//  private string $id = "0b13e52d-b058-32fb-8507-10dec634a07c";
//  private string $username = "zetta86";
//  private string $email = "admin@site.com";
//}

Get raw attributes for entity

$attributes = $factory->of(SuperUser::class)->raw();

//[
//    'id' => "0b13e52d-b058-32fb-8507-10dec634a07c",
//    'username' => 'zetta86',
//    'email' => 'tsteuber@hotmail.com',
//]

Get raw attributes for entity with predefined values

$attributes = $factory->of(SuperUser::class)->raw([
    'email' => 'test@site.com'
]);

//[
//    'id' => "0b13e52d-b058-32fb-8507-10dec634a07c",
//    'username' => 'zetta86',
//    'email' => 'test@site.com',
//]

Generate array of all defined entities

$repository = $factory->make(1000);

$seeds = $repository->get(User::class)->random(100);

$seeds = $repository->get(SuperUser::class)->take(50);

Generate array of raw data for all defined entities

$repository = $factory->raw(1000);

$seeds = $repository->get(User::class)->random(100);

$seeds = $repository->get(SuperUser::class)->take(50);

Export array of raw data to a file for given entity to php file

$path = $factory->of(SuperUser::class)->times(1000)->export('path/to/store');
// path/to/store/SuperUser.php

Export array of raw data to a files for all defined entities

$repository = $factory->export('path/to/store', 1000);
$seeds = $repository->get(User::class)->random(100);

Custom entity builder

You can define your own EntityBuilder class with custom persist logic.

        });

        });
    }

    public function store(object $entity): void
    {
        $this->transaction->persist($entity);
    }
