Overview of this book

Do you want to develop reliable and secure applications that stand out from the crowd without spending hours on boilerplate code? You’ve made the right choice trusting the Django framework, and this book will tell you why. 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 will take you through all the essential concepts and help you explore its power to build real-world applications using Python. Throughout the book, you’ll get the grips with the major features of Django 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 presented as exercises and activities, allowing you to challenge yourself in an enjoyable and attainable way. As you advance, you'll acquire 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. You’ll cover everyday tasks that are part of the development cycle of a real-world web application. By the end of this Django book, you'll have the skills and confidence to creatively develop and deploy your own projects.

In the preceding chapters, we focused on building our web application in Django by writing different components such as database models, views, and templates. We did all that to provide our users with an interactive application where they can create a profile and write reviews for the books they have read.

Apart from building and running the application, there is another important aspect of making sure that the application code works the way we expect it to work. This is ensured by a technique called testing. In testing, we run the different parts of the web application and check whether the output of the executed component matches the output we expected. If the output matches, we say that the component was tested successfully, while if the output doesn’t match, we say that the component failed to work as intended.

In this chapter, as we go through the different sections, we will learn why testing is important, the different ways to test...
