Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Building JWT unit tests

All our models do is read and write to the database. This has been shown to work. The only module left that we’ll unit test is the auth module. Here, we have some logic that has multiple outcomes based on the inputs. We also must do some mocking as some of the functions accept actix_web structs, which have certain fields and functions. Luckily for us, actix_web has a test module that enables us to mock requests.

Building a configuration for tests

Before we start building our unit tests for the JWT, we must remember that there is a dependency on the config file to get the secret key. Unit tests must be isolated. They should not need to have the correct parameters passed into them to work. They should work every time in isolation. Because of this, we are going to have to build a new function for our Config struct in our src/config.rs file. The outline for the coding tests will look like the following code:

impl Config {
