In this chapter, we took advantage of the features included in Django REST Framework to define throttling policies. We used filtering, searching, and ordering classes to make it easy to configure filters, search queries, and desired order for the results in HTTP requests. We used the browsable API feature to test these new features included in our API.

We wrote the first round of unit tests, measured test coverage, and then we wrote additional unit tests to improve test coverage. Finally, we understood many considerations for deployment and scalability.

Now that we built a complex API with Django REST Framework and tested it, we will move to another popular Python web framework, Flask, which is what we are going to discuss in the next chapter.
