Splitting Side Effects in Model Tests

It’s time to test the M of the MVC: the model. We’ll split model tests by their reliance on side effects. Phoenix, like Rumbl.ConnCase, generates a module in test/support/model_case.ex to serve as a foundation for your model tests. Crack it open so you can import our TestHelpers, like this:

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

defmodule Rumbl.ModelCase do
  use ExUnit.CaseTemplate

  using do
    quote do
      alias Rumbl.Repo

      import Ecto
      import Ecto.Changeset
      import Ecto.Query, only: [from: 1, from: 2]
      import Rumbl.TestHelpers 
      import Rumbl.ModelCase
    end
  end
