Summary

In this chapter, we discussed two very important stages in the development of a Dialogue system: testing and deployment. Testing is very important for us to ensure the intelligence of a Dialogue system. We must find the current problems of the Dialogue system through testing and correct these problems. We also discussed how to deploy Rasa projects to production environments. A real large-scale Dialogue system needs to be accessed by tens of thousands or even millions of users at the same time. Such a Dialogue system must have very good horizontal scalability. Fortunately, Rasa considered these issues at the beginning of the design and provided corresponding solutions. By using a central storage system, tracker store, and lock store, we are able to extend our service smoothly.

In the next chapter, we will discuss a user-centered methodology and the tools required for developing Dialogue systems.
