+ * Repeatedly call `iteratee` until `test` returns `true`. Calls `callback` when
+ * stopped, or an error occurs. `callback` will be passed an error and any

+ * @param {AsyncFunction} test - asynchronous truth test to perform before each
+ * execution of `iteratee`. Invoked with (callback).
+ * @param {AsyncFunction} iteratee - An async function which is called each time
+ * `test` fails. Invoked with (callback).
+ * @param {Function} [callback] - A callback which is called after the test
+ * function has passed and repeated execution of `iteratee` has stopped. `callback`
+ * will be passed an error and any arguments passed to the final `iteratee`'s
+ * callback. Invoked with (err, [results]);
+ * @returns {Promise} a promise, if a callback is not passed
+ *
+ * @example
+ * const results = []
+ * let finished = false
+ * async.until(function test(cb) {
+ *     cb(null, finished)
