Python Microservices Development – 2nd edition - Second Edition

By: Simon Fraser, Tarek Ziadé

Overview of this book

The small scope and self-contained nature of microservices make them faster, cleaner, and more scalable than code-heavy monolithic applications. However, building microservices architecture that is efficient as well as lightweight into your applications can be challenging due to the complexity of all the interacting pieces. Python Microservices Development, Second Edition will teach you how to overcome these issues and craft applications that are built as small standard units using proven best practices and avoiding common pitfalls. Through hands-on examples, this book will help you to build efficient microservices using Quart, SQLAlchemy, and other modern Python tools In this updated edition, you will learn how to secure connections between services and how to script Nginx using Lua to build web application firewall features such as rate limiting. Python Microservices Development, Second Edition describes how to use containers and AWS to deploy your services. By the end of the book, you’ll have created a complete Python application based on microservices.

Different kinds of tests

There are many kinds of tests, and it can be confusing sometimes to know what is being spoken about. For instance, when people refer to functional tests, they may be referring to different kinds of tests depending on the project's nature. In microservice land, we can classify tests into these five distinct goals:

  • Unit tests: These make sure a class or a function works as expected in isolation.
  • Functional tests: Verify that the microservice does what it says from the consumer's point of view, and behaves correctly, even upon receiving bad requests.
  • Integration tests: Verify how a microservice integrates with all its network dependencies.
  • Load tests: Measure the microservice performances.
  • End-to-end tests: Verify that the whole system works—from initial request to final action—through all its components.

We will dive deeper into the details in the following sections.
