Laravel 9 Generate Test or Dummy Data using Factory Tinker

If you need to see the example of laravel 9 factory tinker example. it's a simple example of laravel 9 factory seeder. it's a simple example of laravel 9 factories. This article will give you a simple example of a laravel 9 factory tutorial. Let's see below the example laravel 9 test record generate.

As we know testing is a very important part of any web development project. Sometimes we may require to add hundreds of records in your 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. So what you will do at that moment, You will add manually thousands of records? What do you do ?. If you add manually thousands of records then it can take more time.

However, Laravel has a tinker that provides to create dummy records to your model table. so in the laravel application, they provide a User model factory created by default. so 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 on 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 like 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 bellow command:

php artisan make:factory ProductFactory --model=Product

Now they created new factory class for product and you can add as bellow code:

database\factories\ProductFactory.php

<?php
  
namespace Database\Factories;
  
use App\Models\Product;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
  
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()
    {
        return [
            'name' => $this->faker->name,
            'slug' => Str::slug($this->faker->name),
            'detail' => $this->faker->text,
        ];
    }
}

Using Faker you can be used to 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 products table by following command:

Generate Dummy Product:

php artisan tinker
Product::factory()->count(500)->create()

So i hope you created your 500 dummy records on products table.

Output:

I hope it can help you...
