API

wait.until(callback, intervalMs, maxWaitTimeMs)

callback -- Is called on an interval until the result is truthy. If it returns a promise, then the value the promise is resolved with will be checked instead.

intervalMs -- How often to call the callback.

maxWaitTimeMs -- If the callback does not return or resolve to a truthy value within this time limit in milliseconds, then the Promise returned by wait.until will reject.
