README

Automatically generate class-based 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

Version support

Package	Laravel	PHP
2.x	10.x - 13.x	8.1+
v1.3.2	8.x - 9.x	7.3+
v1.2.5	6.x - 7.x	7.2+

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

<?php

declare(strict_types=1);

namespace Database\Factories;

use App\Models\User;
use Illuminate\Support\Str;
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' => fake()->name,
            'username' => fake()->userName,
            'email' => fake()->safeEmail,
            'password' => bcrypt(fake()->password),
            'company_id' => \App\Models\Company::factory(),
            'remember_token' => Str::random(10),
        ];
    }
}

Nullable columns use fake()->optional(), related models resolve to their own ::factory() calls, and the customizable template controls the final shape.

Advanced usage

Selecting models

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

php artisan generate:factory User Company

Overwriting existing factories

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

Customizing the output directory

By default, it will search recursively for models under the app/Models directory.

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

Customizing the namespace

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

Using recursive mode

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

Customizing the factory template

If you want you can customize the factory template to suit your needs.

To publish a factory template to resources/views/vendor/factory-generator/factory.blade.php, run the artisan command:

php artisan vendor:publish --tag="factory-generator"
