Cloud Native Python

By: Manish Sethi

Overview of this book

Businesses today are evolving so rapidly that having their own infrastructure to support their expansion is not feasible. As a result, they have been resorting to the elasticity of the cloud to provide a platform to build and deploy their highly scalable applications. This book will be the one stop for you to learn all about building cloud-native architectures in Python. It will begin by introducing you to cloud-native architecture and will help break it down for you. Then you’ll learn how to build microservices in Python using REST APIs in an event driven approach and you will build the web layer. Next, you’ll learn about Interacting data services and building Web views with React, after which we will take a detailed look at application security and performance. Then, you’ll also learn how to Dockerize your services. And finally, you’ll learn how to deploy the application on the AWS and Azure platforms. We will end the book by discussing some concepts and techniques around troubleshooting problems that might occur with your applications after you’ve deployed them. This book will teach you how to craft applications that are built as small standard units, using all the proven best practices and avoiding the usual traps. It's a practical book: we're going to build everything using Python 3 and its amazing tooling ecosystem. The book will take you on a journey, the destination of which, is the creation of a complete Python application based on microservices over the cloud platform

Testing the RESTful API

So far, we have been building the RESTful API and hitting the URL for the root URL to see the response and to understand whether the different methods are working properly in the backend or not. Since it's new code, everything should be tested 100% to make sure it works fine in the production environment. In this section, we will write the test cases, which should work individually, and also as a system, to make sure that the complete backend service is good to go for production.

There are different types of testing, which are defined as follows:

  • Functional testing: This is basically used to test the functionality of a component or a system. We do this test against the functional specification of a component.
  • Non-function testing: This kind of testing is done against the quality characteristics of a component, which includes efficiency testing, reliability...
