This module defines the setup for tests requiring

You may define functions here to be used as helpers in

your tests.

we enable the SQL sandbox, so changes done to the database

are reverted at the end of every test. If you are using

PostgreSQL, you can even run database tests asynchronously

by setting `use Mv.DataCase, async: true`, although

this option is not recommended for other databases.
