What is database seeding in Laravel?

Laravel includes a simple method of seeding your database with test data using seed classes. All seed classes are stored in database/seeds. Seed classes may have any name you wish, but probably should follow some sensible convention, such as UsersTableSeeder, etc. By default, a DatabaseSeeder class is defined for you. From this class, you may use the call method to run other seed classes, allowing you to control the seeding order.

Writing Seeders

php artisan make:seeder UsersTableSeeder
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class DatabaseSeeder extends Seeder
     * Run the database seeds.
     * @return void
    public function run()
            'name' => str_random(10),
            'email' => str_random(10).'@gmail.com',
            'password' => bcrypt('secret'),

Running Seeders

Once you have written your seeder classes, you may use the db:seed Artisan command to seed your database. By default, the db:seed command runs the DatabaseSeeder class, which may be used to call other seed classes. However, you may use the --class option to specify a specific seeder class to run individually:

php artisan db:seed 
php artisan db:seed --class=UserTableSeeder 

You may also seed your database using the migrate:refresh command, which will also rollback and re-run all of your migrations. This command is useful for completely re-building your database:
