Hands-On RESTful Python Web Services - Second Edition

Summary

In this chapter, we understood the difference between synchronous and asynchronous execution. We created a new version of the RESTful API that takes advantage of the non-blocking features in Tornado, combined with an asynchronous execution. We improved the scalability of our existing API and made it possible to start executing other requests while waiting for slow I/O operations with sensors and actuators. We avoided splitting our methods into multiple methods with callbacks by using the tornado.gen generator-based interface that Tornado provides, to make it easier to work in an asynchronous environment.

Then, we set up a testing environment. We installed pytest, along with many plugins, to make it easy to discover and execute unit ...
