| * @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` |

| * callback. Invoked with (err, [results]); |
