31   * @param {AsyncFunction} test - asynchronous truth test to perform before each
32   * execution of `iteratee`. Invoked with (callback).
33   * @param {AsyncFunction} iteratee - An async function which is called each time
34   * `test` fails. Invoked with (callback).
35   * @param {Function} [callback] - A callback which is called after the test
36   * function has passed and repeated execution of `iteratee` has stopped. `callback`
37   * will be passed an error and any arguments passed to the final `iteratee`'s
38   * callback. Invoked with (err, [results]);
39   * @returns {Promise} a promise, if a callback is not passed
