Mock Objects vs Test Database

Question

What\'s the advantage of using mock objects in comparison to a static test database that has known data and using transactions to make sure nothing changes when testing against

Answer 1

If you can ensure that the static test db doesn't change during testing then I think static test db is better than mock objects. But, then it depends on what you want to test and the complexity of the code being tested. I would go with mock objects as they are simpler to maintain compared with a db.
