Testing the Information System

We’ll start with perhaps our most significant testing challenge. We have quite a bit of behavior to cover, such as timeouts and forced backend termination. You’ll be surprised at how quickly we can cover all this functionality with a few short and sweet test cases. Let’s get started.

A natural first step for testing our InfoSys is to simply look for successful results. Replace your rumbrella/apps/info_sys/test/info_sys_test.exs with the following code:

testing_otp/listings/rumbrella/apps/info_sys/test/info_sys_test.change1.exs

defmodule InfoSysTest do
  use ExUnit.Case
  alias InfoSys.Result

  defmodule TestBackend do 
    def start_link(query, ref, owner, limit) do
 Task.start_link(__MODULE__, ...
