如何为laravel测试播种数据库迁移？

php artisan make:migration create_seeds_table --create=seeds

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateSeedsTable extends Migration
{
    public function up()
    {
        Schema::create('seeds', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->timestamps();
        });
    }

    // 省略了down方法，可根据需要自行编写
}

php artisan migrate

php artisan make:seeder SeedsTableSeeder

use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;

class SeedsTableSeeder extends Seeder
{
    public function run()
    {
        DB::table('seeds')->insert([
            'name' => 'Seed Data',
            'created_at' => now(),
            'updated_at' => now(),
        ]);
    }
}

php artisan db:seed --class=SeedsTableSeeder
