Everything you are describing is about actually testing the database. A database is a complex server and things like db triggers and store procedures should be tested isolation too. And then you have integration tests too.

My team just found a bug that wasn’t covered in a unit test. We found it in a long running API test. And so we added a unit test for the specific low level miss, and a quick integration test too.
