In this article, I will show you How to generate fake data using factory tinker in laravel 11 application. As we know, testing is a very important part of any web development project. Sometimes we may require to add hundreds of records to our users table, or maybe thousands of records. Also, think about if you require to check pagination, then you have to add some records for testing. You Can Learn How to Install and Use Trix Editor in Laravel 11

So what will you do at that moment? Will you manually add thousands of records? What do you do? If you add manually thousands of records, then it can take more time.

How to generate fake data using factory tinker in laravel 11

However, Laravel has a tinker that provides the ability to create dummy records for your model table. So in the Laravel application, they provide a User model factory created by default. You can see how to create records using the factory below:

Generate Dummy Users:

php artisan tinker
    
User::factory()->count(5)->create()

This by default created a factory of Laravel. You can also see that at the following URL: `database/factories/UserFactory.php`.

Create Custom Factory:

But when you need to create dummy records for your products, items, or admin table, then you have to create a new factory using the tinker command. Here, I will give you a simple example of creating a product factory, and you will understand how it works. So let’s create a Product Model as shown below:

app\Models\Product.php

<?php
    
namespace App\Models;
    
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
    
class Product extends Model
{
    use HasFactory;
    
    protected $fillable = [
        'name', 'slug', 'detail'
    ];
}

Now let’s create our custom factory using the below command:

php artisan make:factory ProductFactory --model=Product

Now they created a new Factory class for products, and you can add the code below:

database\factories\ProductFactory.php

<?php
  
namespace Database\Factories;
  
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
use App\Models\Product;
  
/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory
 */
class ProductFactory extends Factory
{
  
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Product::class;
      
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition(): array
    {
        return [
            'name' => $this->faker->name,
            'slug' => Str::slug($this->faker->name),
            'detail' => $this->faker->text,
        ];
    }
}

Using Faker, you can generate the following data types:

• Numbers
• Lorem text
• Person i.e. titles, names, gender etc.
• Addresses
• Phone numbers
• Companies
• Text
• DateTime
• Internet i.e. domains, URLs, emails etc.
• User Agents
• Payments i.e. MasterCard
• Colour
• Files
• Images
• uuid
• Barcodes

As you see above, you can simply use data types. Now we are going to create 500 records of the products table by following command:

Generate Dummy Product:

php artisan tinker

Product::factory()->count(500)->create()

So I hope you’ve created your 500 dummy records in the products table. You Can Learn How to Image Upload with CKeditor in Laravel 11 Tutorial
