 /// This library is used for testing asynchronous tests.
 /// If a test is asynchronous, it needs to notify the testing driver
 /// about this (otherwise tests may get reported as passing [after main()
 /// finished] even if the asynchronous operations fail).
 /// Tests which can't use the unittest framework should use the helper functions
 /// in this library.
 /// This library provides four methods
 ///  - asyncStart(): Needs to be called before an asynchronous operation is
 ///                  scheduled.
 ///  - asyncEnd(): Needs to be called as soon as the asynchronous operation
 ///                ended.
 ///  - asyncSuccess(_): Variant of asyncEnd useful together with Future.then.
 ///  - asyncTest(f()): Helper method that wraps a computation that returns a
 ///                    Future with matching calls to asyncStart() and
 ///                    asyncSuccess(_).
 /// After the last asyncStart() called was matched with a corresponding
 /// asyncEnd() or asyncSuccess(_) call, the testing driver will be notified that
 /// the tests is done.

 // It would be nice if we could use a different mechanism for different
 // runtimes.
