  # SETUP FUNCTIONS
  #
  # Example:   setup [:fun_one, :fun_two]
  #
  # These functions help to prepare a test before execution. They
  # receive a map with the context, returns `{:ok, new_context}`, and are
  # chainable between them.
  #
  # ## Full example:
  #
  #     describe "block" do
  #       setup [:fun_one, :fun_two]
  #       test "one plus two", %{one: one, two: two} do
  #         assert one + two = 3
  #       end
  #     end
  #     defp fun_one(ctx), do: {:ok, Map.put(ctx, :one, 1)}
  #     defp fun_two(ctx), do: {:ok, Map.put(ctx, :two, ctx.one + 1)}
