Recommend to load fixtures in `function _before()` and set `cleanup: false`?

I'm observing that with `cleanup: true`, running external commands with `$I->runShellCommand('php bin/console ...');` isn't working. I'm guessing this is due to the transaction, which prevents external processes to "see" the database contents created/modified by the test. Can you confirm this?

If so, I would suggest to change the recommendation at https://codeception.com/docs/modules/Doctrine to `cleanup: false`, and show people how to load their fixtures in `function _before()`:
```php
$I->runShellCommand('php bin/console doctrine:fixtures:load --no-interaction --env=test');
```

IMO the currently recommended way to cleanup after each test doesn't work out, since for *some tests* it's necessary to disable the transaction (see above) - which ultimately leads to a mess.
So I'm figuring the best approach would be to just reload the fixtures before each test.

What do you think? How do you handle that?

まず https://codeception.com/docs/modules/Doctrine にある Doctrine モジュールのドキュメントと、cleanup、_before()、runShellCommand()、doctrine:fixtures:load を使用している issue の例を読んでください。cleanup のトランザクションによってテストの変更が外部コマンドから隠されるかどうかを再現し、その後、ドキュメントで cleanup: false と各テスト前の fixture の読み込みを推奨すべきかどうかを判断してください。
