laravel 5.5 测试数据seed

1：/database/factories中UserFactory中修改
$factory->define(App\User::class, function (Faker $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->unique()->safeEmail,
        'password' =>bcrypt(str_random(10)), // secret
        'remember_token' => str_random(10),
    ];
});
2:先创建users表的seeder;
php artisan make:seeder UsersTableSeeder

3：在/database/seeds/UsersTableSeeder.php；在run()添加调用user类；生成user表中的10个实例

    public function run()
    {
     factory(\App\User::class,10)->create();
    }
4:在DataTableSeeder中call()调用UsersTableSeeder
///database/seeds/DataTableSeeder.php
//是对数据填充限制的操作。所以unguard在前，reguard在后，unguard负责解除自动填充操作限制，reguard负责恢复限制。
   
   public function run()
    {
	 Model::unguard();
	 App\User::truncate();
         $this->call(UsersTableSeeder::class);
	 Model::reguard();
    }
5:生成测试数据
php artisan db:seed //执行所有的seeder
php artisan db:seed --class=你要执行的类名称  //执行某个seeder
