In this chapter, we discussed how developers can go about thoroughly testing RESTful web services. Beyond traditional unit testing, we covered security testing, integration testing, and briefly touched upon other types of testing such as UAT and load testing.

So far in this book, we have looked at web services from the server's side. However, for any such service, and indeed any piece of software, to be useful, it needs to be used. In our context, a RESTful web service is useful only if it is consumed by clients.

In the next chapter, we will look at how to build a client using Spring.
