This module defines the test case to be used by
tests that require setting up a connection.
Such tests rely on `Phoenix.ConnTest` and also
import other functionality to make it easier
to build common data structures and query the data layer.
Finally, if the test case interacts with the database,
it cannot be async. For this reason, every test runs
inside a transaction which is reset at the beginning
of the test unless the test case is marked as async.
