This can become a challenge when you want to scale a dev team. You either have people conflicting in the DB, or each dev needs to set up a local DB and deal with DB migrations. Containerized DBs help with this to some extent, but it's still a maintenance headache. There's also a tradeoff around testing error states, but that can be a wash. Some errors are easier to create with a mock, some are easier to create with the actual driver.
