defmodule WeatherTrackerWeb.ChannelCase do @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 WeatherTrackerWeb.ChannelCase, async: true`, although this option is not recommended for other databases.
