defmodule MemexWeb.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 common data structures and query the data layer.
Finally, if the test case interacts with the database,
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 MemexWeb.ConnCase, async: true`, although
this option is not recommended for other databases.
