Laravel Factory Generator

Automatically generate factories from your existing models.

It will allow you to write tests containing your models much faster.

Installation

You can install the package via composer:

composer require thedoctor0/laravel-factory-generator --dev

Usage

To generate all factories at once, simply run this artisan command:

php artisan generate:factory

It will find all models and generate test factories based on the database structure and model relations.

Example

Migration and Model

Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('username');
    $table->string('email')->unique();
    $table->string('password', 60);
    $table->integer('company_id');
    $table->rememberToken();
    $table->timestamps();
});

class User extends Model {
    public function company()
    {
        return $this->belongsTo(Company::class);
    }
}

Generated Factory

For Laravel 6.x and 7.x:

<?php

declare(strict_types=1);

use Faker\Generator as Faker;

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'username' => $faker->userName,
        'email' => $faker->safeEmail,
        'password' => bcrypt($faker->password),
        'company_id' => factory(App\Company::class),
        'remember_token' => Str::random(10),
    ];
});

For Laravel 8.x and up:

<?php

declare(strict_types=1);

namespace Database\Factories;

use App\Models\Contact;
use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends Factory<\App\Models\User>
 */
final class UserFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = User::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition(): array
    {
        return [
            'name' => $this->faker->name,
            'username' => $this->faker->userName,
            'email' => $this->faker->safeEmail,
            'password' => bcrypt($this->faker->password),
            'company_id' => \App\Company::factory(),
            'remember_token' => Str::random(10),
        ];
    }
}

Advanced usage

To generate a factory for only specific model or models, run the artisan command:

php artisan generate:factory User Company

---

By default, generation will not overwrite any existing model factories.

You can force overwriting existing model factories by using the --force option:

php artisan generate:factory --force

---

By default, it will search recursively for models under the app/Models (Laravel 8.x and up) or app for (Laravel 6.x and 7.x).

If your models are within a different folder, you can specify this using --dir option.

In this case, run the artisan command:

php artisan generate:factory --dir app/Models

---

If your models are within a different namespace, you can specify it using --namespace option.

You just need to execute this artisan command:

php artisan generate:factory --dir vendor/package/src/Models --namespace CustomNamespace\\Models

---

By default, your model directory structure is not taken into account, even though it has subdirectories.

You can reflect it to database/factories directory by using the --recursive option:

php artisan generate:factory --recursive
