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 8. Writing Testable Code

With this chapter, we have entered part two of our book, which covers the development of enterprise-grade applications using Python. While part one of this book focused on how to build an enterprise-grade application with scalability and performance in mind, part two of this book focuses on the internal development aspects of the application, such as how we can make sure our application is secure, how well it is performing, and how to ship an application with the higher quality checks in place so as to minimize the occurrence of unexpected behaviors during the production phase.

In this chapter, we would like to bring your focus to a very important aspect of the enterprise application development or, for that sake, an important aspect for the development of any kind of application. This important aspect is the testability of the code.

Writing code that can be easily tested can prove to be really useful. This involves the ability to identify bugs early in the...
