By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Chapter 12: Testing Your Application

Ensuring that a program runs correctly is an important part of programming. In this chapter, we are going to learn about testing the Rust application. We are going to implement a simple unit test for a function, and a functional test for creating a user in our application.

We are going to learn a simple technique to debug and find where a problem occurs in our code.

After learning the information in this chapter, you will be able to create a unit test and functional test for Rust and Rocket applications to ensure the applications work as expected. You will also learn how to use a debugger such as gdb or lldb to debug Rust programs.

In this chapter, we are going to cover these main topics:

  • Testing the Rust program
  • Testing the Rocket application
  • Debugging the Rust application
