Botium Crawler simulates user clicks on all of the options in parallel, following all paths down until it reaches the end of the conversation or a certain criteria. It will help you to identify missing paths and dead ends in the conversation flow and will help you to provide great user experience no matter what path the user takes. The additional benefit of the crawler is that all detected conversation flows along all paths can be saved as Botium test cases and utterance lists and can be used as a base for a regression test set.
