19 * Repeatedly call `iteratee` until `test` returns `true`. Calls `callback` when
20 * stopped, or an error occurs. `callback` will be passed an error and any
21 * arguments passed to the final `iteratee`'s callback.

23 * The inverse of [whilst]{@link module:ControlFlow.whilst}.

30 * @category Control Flow
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
40 *
41 * @example
42 * const results = []
43 * let finished = false
44 * async.until(function test(cb) {
