+/**
+ * Like [`doWhilst`](#doWhilst), except the `test` is inverted. Note the
+ * argument ordering differs from `until`.
+ *
+ * @name doUntil
+ * @static
+ * @memberOf async
+ * @see `async.doWhilst`
+ * @category Control Flow
+ * @param {Function} fn - A function which is called each time `test` fails.
+ * The function is passed a `callback(err)`, which must be called once it has
+ * completed with an optional `err` argument. Invoked with (callback).
+ * @param {Function} test - synchronous truth test to perform before each
+ * execution of `fn`. Invoked with ().
+ * @param {Function} [callback] - A callback which is called after the test
+ * function has passed and repeated execution of `fn` has stopped. `callback`
+ * will be passed an error and any arguments passed to the final `fn`'s
+ * callback. Invoked with (err, [results]);
