Flutterが自動テストを推奨していることをどう思うのか？

Testing Flutter apps
https://flutter.dev/docs/testing

Automated testing falls into a few categories:

- A unit test tests a single function, method, or class.
- A widget test (in other UI frameworks referred to as component test) tests a single widget.
- An integration test tests a complete app or a large part of an app.
