defmodule FerricStore.Sandbox.Case do

  @moduledoc """

  ExUnit case template that automatically checks out and checks in a

  FerricStore sandbox for each test.



  Using this module in a test module is equivalent to writing:



      setup do

        sandbox = FerricStore.Sandbox.checkout()

        on_exit(fn -> FerricStore.Sandbox.checkin(sandbox) end)

        %{sandbox: sandbox}

      end



  ## Usage



      defmodule MyApp.CacheTest do

        use ExUnit.Case, async: true

        use FerricStore.Sandbox.Case



        test "transparent isolation" do

          FerricStore.set("key", "value")

          assert {:ok, "value"} = FerricStore.get("key")

        end

      end



  ## Options



  Options passed to `use FerricStore.Sandbox.Case` are forwarded to

  `FerricStore.Sandbox.checkout/1`:



      use FerricStore.Sandbox.Case, freeze_ttl: true
