+ *
+ * In tests you can use `$browser.defer.flush()` to flush the queue of deferred functions.
+ *
+ * @param {function()} fn A function, who's execution should be deferred.
+ * @param {number=} [delay=0] of milliseconds to defer the function execution.
+ * @returns {*} DeferId that can be used to cancel the task via `$defer.cancel()`.
