Time to Choo Choo! Click on Test your bot at the bottom right to test your conversational flow. To get a feel of your bot's performance, ask the same question a couple times, including different ways of asking the question that are different to the expression you used to train. If a question is not correctly recognized, you'll have to go back to the NLP tab, add the questions as an expression, and retrain the NLP model. You can do this as many times as needed, the model will just keep on improving.
