defmodule ExMoney.Web.ChannelCase do
  @moduledoc """
  This module defines the test case to be used by
  channel tests.

  Such tests rely on `Phoenix.ChannelTest` and also
  imports 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.
