Programming Phoenix 1.4

Testing Contexts

It’s time to test the M of the MVC, models. Phoenix generates a module in test/support/data_case.ex to serve as a foundation for your tests that interact with the database. In our case, Accounts and Multimedia contexts both work with the database. The data_case handles setup and teardown of the database and integrates with Ecto.Sandbox to allow concurrent transactional tests. Crack it open and import the fixtures we just defined:

testing_mvc/listings/rumbl/test/support/data_case.change1.ex

defmodule Rumbl.DataCase do
  use ExUnit.CaseTemplate

  using do
    quote do
      alias Rumbl.Repo

      import Ecto
      import Ecto.Changeset
      import Ecto.Query
      import Rumbl.DataCase
      import Rumbl.TestHelpers ...
