【Symfony】Fixtureを使ってテストデータを作ってみる！

composer require orm-fixtures --dev

taka@Taka my_project % php bin/console make:fixtures

 Next: Open your new fixtures class and start customizing it.
 Load your fixtures by running: php bin/console doctrine:fixtures:load

            $user->setName('user'.$i);
            $user->setAge(rand(20, 60));

            $manager->persist($user);
            $manager->flush();

            // UserごとComment 100件分
