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.

Setting up Pytest

Testing your Python code is an essential part of the development process, and Pytest is a powerful tool for actualizing a robust testing environment. In this section, we’ll walk you through the steps of setting up Pytest and transforming your Python code testing experience from amateur into pro, providing advanced features and capabilities that make testing faster, easier, and more effective.

To set up Pytest, you can follow these steps:

  1. Installing pip: You can install Pytest using pip, the package installer for Python. Open your Terminal or command prompt in the bizza/backend/ project directory and run the following command:
    pip install pytest

    The preceding line installs Pytest and all its dependencies.

  2. Creating a test file: Create a new file named test_addition.py in your project directory – that is, bizza/backend/tests/test_addition.py. This is a simple example test file to warm up with.
  3. Writing a test function: Inside test_addition...
