进入database下面的factory

$factory->define(User::class, function (Faker $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->unique()->safeEmail,
        'email_verified_at' => now(),
        'password' => '$2y$10$92IXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', // password
        'remember_token' => Str::random(10),
    ];
});


$factory->define(\App\Models\Post::class, function (Faker $faker) {
   return [
      'title' => $faker->sentence(6),
      'content' => $faker->paragraph(10),
   ];
});

然后进入目录使用tinker
php artisan tinker
执行 

    factory(App\Models\Post::class,50)->make()
