 * @assertion abstract Future addStream(Stream<T> source,
 *                                      {bool cancelOnError: true})
 * Receives events from source and puts them into this controller's stream.
 * Returns a future which completes when the source stream is done.
 * Data and error events are forwarded to this controller's stream. A done
 * event on the source will end the addStream operation and complete the
 * returned future.
 * @description Checks that data events from source are added correctly and that
 * returned future completes when the source ends.
