Web Development with Django

Overview of this book

Do you want to develop reliable and secure applications which stand out from the crowd, rather than spending hours on boilerplate code? Then the Django framework is where you should begin. Often referred to as a 'batteries included' web development framework, Django comes with all the core features needed to build a standalone application. Web Development with Django takes this philosophy and equips you with the knowledge and confidence to build real-world applications using Python. Starting with the essential concepts of Django, you'll cover its major features by building a website called Bookr – a repository for book reviews. This end-to-end case study is split into a series of bitesize projects that are presented as exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. As you progress, you'll learn various practical skills, including how to serve static files to add CSS, JavaScript, and images to your application, how to implement forms to accept user input, and how to manage sessions to ensure a reliable user experience. Throughout this book, you'll cover key daily tasks that are part of the development cycle of a real-world web application. By the end of this book, you'll have the skills and confidence to creatively tackle your own ambitious projects with Django.

Preface

Testing in Django

Django is a feature-packed framework that aims to make web application development rapid. It provides a full-featured way of testing an application. It also provides a well-integrated module that allows application developers to write unit tests for their applications. This module is based on the Python unittest library that ships with most Python distributions.

Let us get started with understanding how we can write basic test cases in Django and how to leverage the framework-provided modules to test our application code.

Implementing Test Cases

When working on implementing mechanisms for testing your code, the first thing that needs to be understood is how this implementation can be logically grouped, such that modules that are closely related to each other are tested in one logical unit.

This is simplified by implementing a test case. A test case is nothing more than a logical unit that groups together tests that are related to logically similar units...
