Overview of this book

Developing an interactive, efficient, and fast enterprise web application requires both the right approach and tooling. If you are a web developer looking for a way to tap the power of React’s reusable UI components and the simplicity of Flask for backend development to develop production-ready, scalable web apps in Python, then this book is for you. Starting with an introduction to React, a JavaScript library for building highly interactive and reusable user interfaces, you’ll progress to data modeling for the web using SQLAlchemy and PostgreSQL, and then get to grips with Restful API development. This book will aid you in identifying your app users and managing access to your web application. You’ll also explore modular architectural design for Flask-based web applications and master error-handling techniques. Before you deploy your web app on AWS, this book will show you how to integrate unit testing best practices to ensure code reliability and functionality, making your apps not only efficient and fast but also robust and dependable. By the end of this book, you’ll have acquired deep knowledge of the Flask and React technology stacks, which will help you undertake web application development with confidence.

Writing unit tests

Writing tests with pytest involves creating test functions that verify the functionality of your code. These test functions are executed by pytest and can be organized into test modules and test packages. In addition to test functions, pytest provides other testing features such as fixtures, parameterization, and mocking, which can help you write more robust and efficient tests.

In this section, we will cover the basics of writing tests with pytest, including creating test functions, using assertions to check for expected behavior, and organizing tests into test suites.

Now, let’s laser-focus on writing unit tests for a user registration component of an application.

Unit-testing user registration

Unit testing is a crucial part of the software development process. Unit testing unarguably allows developers to verify that their code works correctly and reliably, as stated earlier. One area where unit testing is particularly important is user registration...
