-  @moduledoc """
-  This module defines the test case to be used by
-  channel tests.
-
-  Such tests rely on `Phoenix.ChannelTest` 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 BirdyChatWeb.ChannelCase, async: true`, although
-  this option is not recommended for other databases.
