Hi @jkarel, do you mean e2e test conversations? If so, do you want to generate them based on the NLU data you have - a random selection of it for each intent? Or just intent: /intent?
I did something like this (generating e2e test conversations) once but don’t have access to the code anymore; I can say there were considerably more pitfalls than I anticipated at first e.g. required entities in NLU, mixture of NLU and button input expected, etc.
While I definitely see the attraction of automating this, I’d recommend not to go to that effort at first; if you’re still in the early stages of your bot, adding tests as you go is generally better. In Rasa X, you can add tests from user conversations - see Test Your Assistant. This is often better because your tests aren’t just an amalgamation of training data, but instances of conversations that users really had.
