Overview of this book

Are safety and high performance a big concern for you while developing web applications? While most programming languages have a safety or speed trade-off, Rust provides memory safety without using a garbage collector. This means that with its low memory footprint, you can build high-performance and secure web apps with relative ease. This book will take you through each stage of the web development process, showing you how to combine Rust and modern web development principles to build supercharged web apps. You'll start with an introduction to Rust and understand how to avoid common pitfalls when migrating from traditional dynamic programming languages. The book will show you how to structure Rust code for a project that spans multiple pages and modules. Next, you'll explore the Actix Web framework and get a basic web server up and running. As you advance, you'll learn how to process JSON requests and display data from the web app via HTML, CSS, and JavaScript. You'll also be able to persist data and create RESTful services in Rust. Later, you'll build an automated deployment process for the app on an AWS EC2 instance and Docker Hub. Finally, you'll play around with some popular web frameworks in Rust and compare them. By the end of this Rust book, you'll be able to confidently create scalable and fast web applications with Rust.

Chapter 9: Testing Our Application Endpoints and Components

Our to-do Rust application now fully works. We are happy with our first version as it manages authentication, different users and their to-do lists, and logs our processes for inspection. However, a web developer's job is never done.

While we have now come to the end of adding features to our application, we know that the journey does not stop here. In future iterations beyond this book, we may want to add teams, new statuses, multiple lists per user, and so on. However, as we add these features, we have to ensure that our old application behavior stays the same unless we actively change it. This is done by building tests.

In this chapter, we'll build tests that check our existing behavior, laying down traps that will throw errors that report to us if the behavior changes without us actively changing it. This prevents us from breaking the application and pushing it to a server after adding a new feature or...
