Laravel - P31: Faker Library (Dino Cajic)

Laravel — P31- Faker

Enhancing Laravel Data with Faker: Realistic Testing Made Easy

What’s a faker? It’s exactly as it sounds. You’re trying to fake something. Instead of coming up with the data yourself, you simply state, “Faker, give me a unique random email address,” and faker spits it out for you.

In Laravel, Faker is a library that generates fake data for testing purposes. It can be used to generate random names, addresses, phone numbers, email addresses, and other types of fake data that can be used to populate databases and test applications.

Laravel — P30: Factories

You can start using the faker library automatically. The Faker PHP library is pretty powerful and makes generating random names, emails, etc, incredibly easy. You can read the Faker documentation to find out more.

In our case, we just want a random name and a unique email. We can return the code in the UserFactory to its original state.

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\User>
 */
class UserFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            'name' => fake()->name(),
            'email' => fake()->unique()->safeEmail(),
            'email_verified_at' => now(),
            'password' => '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', // password
            'remember_token' => Str::random(10),
        ];
    }

    /**
     * Indicate that the model's email address should be unverified.
     *
     * @return static
     */
    public function unverified()
    {
        return $this->state(fn (array $attributes) => [
            'email_verified_at' => null,
        ]);
    }
}

We can test to make sure that it’s working by running the same factory()->make() command in tinker. You can run this code as many times as you’d like and faker will generate new users each time.

# php artisan tinker

= App\Models\User {#3828
    name: "Dr. Rosario Schinner MD",
    email: "elouise.howell@example.com",
    email_verified_at: "2023-01-15 23:08:56",
    #password: "$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi",

    created_at: "2023-01-15 23:08:56",
    id: 5,
  }

If you’re not getting the results that you were expecting, and currently have tinker open, you’ll need to close it (CTRL + C) and re-open it. You can now use your factory with faker to generate random users whenever you need them just like before.

What if you wanted to generate 50 users? Laravel makes this painless as well. Let’s look at it in tinker again.

> User::factory()->count(50)->create();
= Illuminate\Database\Eloquent\Collection {#3798

And just like that, you have 50 new users with the help of the count() method that’s been chained on. If you don’t want to persist the data, you can use the make() method.

Check the users table in your database to verify that you have 50 new users.
