Hands-On Enterprise Application Development with Python

By: Saurabh Badhwar

Overview of this book

Dynamically typed languages like Python are continuously improving. With the addition of exciting new features and a wide selection of modern libraries and frameworks, Python has emerged as an ideal language for developing enterprise applications. Hands-On Enterprise Application Development with Python will show you how to build effective applications that are stable, secure, and easily scalable. The book is a detailed guide to building an end-to-end enterprise-grade application in Python. You will learn how to effectively implement Python features and design patterns that will positively impact your application lifecycle. The book also covers advanced concurrency techniques that will help you build a RESTful application with an optimized frontend. Given that security and stability are the foundation for an enterprise application, you’ll be trained on effective testing, performance analysis, and security practices, and understand how to embed them in your codebase during the initial phase. You’ll also be guided in how to move on from a monolithic architecture to one that is service oriented, leveraging microservices and serverless deployment techniques. By the end of the book, you will have become proficient at building efficient enterprise applications in Python.

Chapter 12. Testing and Tracing in Microservices

Up until now, we have got to see how microservices can help us change the way that we build and deliver our application to production. Be it faster rollouts for new features, or keeping the teams small, microservices enable that for us. But with this architecture, where every single component is a small service in its own, we have got some challenges to solve. These challenges involve how we can aim to ship a stable and bug free application into production while following the microservices approach.

Inside the Monolithic architecture, we had only a small number of moving components that required testing. We could write unit tests to test the individual methods of the Monolithic application, and then move on to integration testing to verify if these components operate correctly with each other. But now, with the advent of microservices, we have got more and more moving components in the picture. Inside the microservices, we have different features...
