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

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

* @name until

* @method
* @see [async.whilst]{@link module:ControlFlow.whilst}
* @category Control Flow
* @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)
* }, function iter(next) {
* fetchPage(url, (err, body) => {
* if (err) return next(err)
* results = results.concat(body.objects)
* finished = !!body.next
* next(err)
* })
* }, function done (err) {
* // all pages have been fetched
* })
