				defmodule Pack.ConnCase do
				@moduledoc """
				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 and query models.

				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.
