* `integration_test/` for integration tests. They should be volatile to follow UI layout changes.
Some rule of thumb:
* `<object>Provider` only placed at `/lib/data/repositories/` or `/lib/data/services/` to provide data source.
* global provider
* `<object>RepositoryProvider` only placed in `/lib/data/repositories/`, provide data to `/lib/ui`.
* `lib/data/services/*` should be stateless, and should only accessible by `Repository`.
