`SpecialMWOAuthManageMyGrants` handles the flow for listing the consumers to which a user has granted access. The user can also manage access to this consumer using this special page or revoke access entirely.
Integration tests would be written to cover the `/list`, `/update`, `/revoke`, and `/manage/<accesstoken>` endpoints and their interaction with the DB. Unit tests would be written for self-contained code paths within and related classes used by this special page. It's probably possible to use `SpecialPageTestBase`, since this will involve testing a special page and `ApiTestCase` for action API-related functionality.
