/// @assertion 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.
